[section:buckets The Data Structure]
|
||||
|
||||
The containers are made up of a number of 'buckets', each of which can contain
|
||||
any number of elements. For example, the following diagram shows an [classref
|
||||
boost::unordered_set unordered_set] with 7 buckets containing 5 elements, `A`,
|
||||
`B`, `C`, `D` and `E` (this is just for illustration, containers will typically
|
||||
have more buckets).
|
||||
|
||||
[diagram buckets]
|
||||
|
||||
In order to decide which bucket to place an element in, the container applies
|
||||
the hash function, `Hash`, to the element's key (for `unordered_set` and
|
||||
`unordered_multiset` the key is the whole element, but is referred to as the key
|
||||
so that the same terminology can be used for sets and maps). This returns a
|
||||
value of type `std::size_t`. `std::size_t` has a much greater range of values
|
||||
then the number of buckets, so that container applies another transformation to
|
||||
that value to choose a bucket to place the element in.
|
||||
|
||||
Retrieving the elements for a given key is simple. The same process is applied
|
||||
to the key to find the correct bucket. Then the key is compared with the
|
||||
elements in the bucket to find any elements that match (using the equality
|
||||
predicate `Pred`). If the hash function has worked well the elements will be
|
||||
evenly distributed amongst the buckets so only a small number of elements will
|
||||
need to be examined.
|
||||
|
||||
There is [link unordered.hash_equality more information on hash functions and
|
||||
equality predicates in the next section].
|
||||
|
||||
You can see in the diagram that `A` & `D` have been placed in the same bucket.
|
||||
When looking for elements in this bucket up to 2 comparisons are made, making
|
||||
the search slower. This is known as a collision. To keep things fast we try to
|
||||
keep collisions to a minimum.

[h2 Controlling the number of buckets]
|
||||
|
||||
As more elements are added to an unordered associative container, the number
|
||||
of elements in the buckets will increase causing performance to degrade.
|
||||
To combat this the containers increase the bucket count as elements are inserted.
|
||||
You can also tell the container to change the bucket count (if required) by
|
||||
calling `rehash`.
|
||||
|
||||
The standard leaves a lot of freedom to the implementer to decide how the
|
||||
number of buckets are chosen, but it does make some requirements based on the
|
||||
container's 'load factor', the average number of elements per bucket.
|
||||
Containers also have a 'maximum load factor' which they should try to keep the
|
||||
load factor below.
|
||||
|
||||
You can't control the bucket count directly but there are two ways to
|
||||
influence it:
|
||||
|
||||
* Specify the minimum number of buckets when constructing a container or
|
||||
when calling `rehash`.
|
||||
* Suggest a maximum load factor by calling `max_load_factor`.
|
||||
|
||||
`max_load_factor` doesn't let you set the maximum load factor yourself, it just
|
||||
lets you give a /hint/. And even then, the draft standard doesn't actually
|
||||
require the container to pay much attention to this value. The only time the
|
||||
load factor is /required/ to be less than the maximum is following a call to
|
||||
`rehash`. But most implementations will try to keep the number of elements
|
||||
below the max load factor, and set the maximum load factor to be the same as
|
||||
or close to the hint - unless your hint is unreasonably small or large.
|
||||
|
||||

|

[[Method] [Description]]
|
||||

|
||||

|

|
||||
[
|
||||
[`float max_load_factor(float z)`]
|
||||
[Changes the container's maximum load factor, using `z` as a hint.]
|
||||
]
|
||||
[
|
||||
[`void rehash(size_type n)`]
|
||||
[Changes the number of buckets so that there at least n buckets, and
|
||||
so that the load factor is less than the maximum load factor.]
|
||||
]
|
||||
|
||||
]
|
||||
|
||||
[h2 Iterator Invalidation]
|
||||
|
||||
It is not specified how member functions other than `rehash` affect
|
||||
the bucket count, although `insert` is only allowed to invalidate iterators
|
||||
when the insertion causes the load factor to be greater than or equal to the
|
||||
maximum load factor. For most implementations this means that insert will only
|
||||
change the number of buckets when this happens. While iterators can be
|
||||
invalidated by calls to `insert` and `rehash`, pointers and references to the
|
||||
container's elements are never invalidated.
|
||||
|
||||
In a similar manner to using `reserve` for `vector`s, it can be a good idea
|
||||
to call `rehash` before inserting a large number of elements. This will get
|
||||
the expensive rehashing out of the way and let you store iterators, safe in
|
||||
the knowledge that they won't be invalidated. If you are inserting `n`
|
||||
elements into container `x`, you could first call:
|
||||
|
||||
x.rehash((x.size() + n) / x.max_load_factor() + 1);
|
||||
|
||||
[blurb Note: `rehash`'s argument is the minimum number of buckets, not the
|
||||
number of elements, which is why the new size is divided by the maximum load factor. The
|
||||
`+ 1` guarantees there is no invalidation; without it, reallocation could occur
|
||||
if the number of bucket exactly divides the target size, since the container is
|
||||
allowed to rehash when the load factor is equal to the maximum load factor.]

[section:changes Change Log]
|
||||
|
||||
[h2 Review Version]
|
||||
|
||||
Initial review version, for the review conducted from 7th December 2007 to
|
||||
16th December 2007.
|
||||
|
||||
[h2 1.35.0 Add-on - 31st March 2008]
|
||||
|
||||
Unofficial release uploaded to vault, to be used with Boost 1.35.0. Incorporated
|
||||
many of the suggestions from the review.
|
||||
|
||||
* Improved portability thanks to Boost regression testing.
|
||||
* Fix lots of typos, and clearer text in the documentation.
|
||||
* Fix floating point to `std::size_t` conversion when calculating sizes from
|
||||
the max load factor, and use `double` in the calculation for greater accuracy.
|
||||
* Fix some errors in the examples.
|
||||
|
||||
[h2 Boost 1.36.0]
|
||||
|
||||
First official release.
|
||||
|
||||
* Rearrange the internals.
|
||||
* Move semantics - full support when rvalue references are available, emulated
|
||||
using a cut down version of the Adobe move library when they are not.
|
||||
* Emplace support when rvalue references and variadic template are available.
|
||||
* More efficient node allocation when rvalue references and variadic template
|
||||
are available.
|
||||
* Added equality operators.
|
||||
|
||||
[h2 Boost 1.37.0]
|
||||
|
||||
* Rename overload of `emplace` with hint, to `emplace_hint` as specified in
|
||||
[@http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2008/n2691.pdf n2691].
|
||||
* Provide forwarding headers at `<boost/unordered/unordered_map_fwd.hpp>` and
|
||||
`<boost/unordered/unordered_set_fwd.hpp>`.
|
||||
* Move all the implementation inside `boost/unordered`, to assist
|
||||
modularization and hopefully make it easier to track changes in subversion.
|
||||
|
||||
[h2 Boost 1.38.0]
|
||||
|
||||
* Use [@boost:/libs/utility/swap.html `boost::swap`].
|
||||
* [@https://svn.boost.org/trac/boost/ticket/2237 Ticket 2237]:
|
||||
Document that the equality and inequality operators are undefined for two
|
||||
objects if their equality predicates aren't equivalent. Thanks to Daniel
|
||||
Krügler.
|
||||
* [@https://svn.boost.org/trac/boost/ticket/1710 Ticket 1710]:
|
||||
Use a larger prime number list. Thanks to Thorsten Ottosen and Hervé
|
||||
Brönnimann.
|
||||
* Use
|
||||
[@boost:/libs/type_traits/doc/html/boost_typetraits/category/alignment.html
|
||||
aligned storage] to store the types. This changes the way the allocator is
|
||||
used to construct nodes. It used to construct the node with two calls to
|
||||
the allocator's `construct` method - once for the pointers and once for the
|
||||
value. It now constructs the node with a single call to construct and
|
||||
then constructs the value using in place construction.
|
||||
* Add support for C++0x initializer lists where they're available (currently
|
||||
only g++ 4.4 in C++0x mode).
|
||||
|
||||
[h2 Boost 1.39.0]
|
||||
|
||||
* [@https://svn.boost.org/trac/boost/ticket/2756 Ticket 2756]: Avoid a warning
|
||||
on Visual C++ 2009.
|
||||
* Some other minor internal changes to the implementation, tests and
|
||||
documentation.
|
||||
* Avoid an unnecessary copy in `operator[]`.
|
||||
* [@https://svn.boost.org/trac/boost/ticket/2975 Ticket 2975]: Fix length of
|
||||
prime number list.
|
||||
|
||||
[h2 Boost 1.40.0]
|
||||
|
||||
* [@https://svn.boost.org/trac/boost/ticket/2975 Ticket 2975]:
|
||||
Store the prime list as a preprocessor sequence - so that it will always get
|
||||
the length right if it changes again in the future.
|
||||
* [@https://svn.boost.org/trac/boost/ticket/1978 Ticket 1978]:
|
||||
Implement `emplace` for all compilers.
|
||||
* [@https://svn.boost.org/trac/boost/ticket/2908 Ticket 2908],
|
||||
[@https://svn.boost.org/trac/boost/ticket/3096 Ticket 3096]:
|
||||
Some workarounds for old versions of borland, including adding explicit
|
||||
destructors to all containers.
|
||||
* [@https://svn.boost.org/trac/boost/ticket/3082 Ticket 3082]:
|
||||
Disable incorrect Visual C++ warnings.
|
||||
* Better configuration for C++0x features when the headers aren't available.
|
||||
* Create less buckets by default.
|
||||
|
||||
[h2 Boost 1.41.0 - Major update]
|
||||
|
||||
* The original version made heavy use of macros to sidestep some of the older
|
||||
compilers' poor template support. But since I no longer support those
|
||||
compilers and the macro use was starting to become a maintenance burden it
|
||||
has been rewritten to use templates instead of macros for the implementation
|
||||
classes.
|
||||
|
||||
* The container objcet is now smaller thanks to using `boost::compressed_pair`
|
||||
for EBO and a slightly different function buffer - now using a bool instead
|
||||
of a member pointer.
|
||||
|
||||
* Buckets are allocated lazily which means that constructing an empty container
|
||||
will not allocate any memory.
|
||||
|
||||
[h2 Boost 1.42.0]
|
||||
|
||||
* Support instantiating the containers with incomplete value types.
|
||||
* Reduced the number of warnings (mostly in tests).
|
||||
* Improved codegear compatibility.
|
||||
* [@http://svn.boost.org/trac/boost/ticket/3693 Ticket 3693]:
|
||||
Add `erase_return_void` as a temporary workaround for the current
|
||||
`erase` which can be inefficient because it has to find the next
|
||||
element to return an iterator.
|
||||
* Add templated find overload for compatible keys.
|
||||
* [@http://svn.boost.org/trac/boost/ticket/3773 Ticket 3773]:
|
||||
Add missing `std` qualifier to `ptrdiff_t`.
|
||||
* Some code formatting changes to fit almost all lines into 80 characters.
|
||||
|
||||
[h2 Boost 1.43.0]
|
||||
|
||||
* [@http://svn.boost.org/trac/boost/ticket/3966 Ticket 3966]:
|
||||
`erase_return_void` is now `quick_erase`, which is the
|
||||
[@http://home.roadrunner.com/~hinnant/issue_review/lwg-active.html#579
|
||||
current forerunner for resolving the slow erase by iterator], although
|
||||
there's a strong possibility that this may change in the future. The old
|
||||
method name remains for backwards compatibility but is considered deprecated
|
||||
and will be removed in a future release.
|
||||
* Use Boost.Exception.
|
||||
* Stop using deprecated `BOOST_HAS_*` macros.

[section:hash_equality Equality Predicates and Hash Functions]
|
||||
|
||||
While the associative containers use an ordering relation to specify how the
|
||||
elements are stored, the unordered associative containers use an equality
|
||||
predicate and a hash function. For example, [classref boost::unordered_map]
|
||||
is declared as:
|
||||
|
||||
template <
|
||||
class Key, class Mapped,
|
||||
class Hash = ``[classref boost::hash]``<Key>,
|
||||
class Pred = std::equal_to<Key>,
|
||||
class Alloc = std::allocator<std::pair<Key const, Mapped> > >
|
||||
class ``[classref boost::unordered_map unordered_map]``;
|
||||
|
||||
The hash function comes first as you might want to change the hash function
|
||||
but not the equality predicate. For example, if you wanted to use the
|
||||
[@http://www.isthe.com/chongo/tech/comp/fnv/ FNV-1 hash] you could write:
|
||||
|
||||
[import src_code/dictionary.cpp]
|
||||
[case_sensitive_dictionary_fnv]
|
||||
|
||||
There is an [@boost:/libs/unordered/examples/fnv1.hpp implementation
|
||||
of FNV-1] in the examples directory.
|
||||
|
||||
If you wish to use a different equality function,
|
||||
you will also need to use a matching hash function. For
|
||||
example, to implement a case insensitive dictionary you need to define a
|
||||
case insensitive equality predicate and hash function:
|
||||
|
||||
[case_insensitive_functions]
|
||||
|
||||
Which you can then use in a case insensitive dictionary:
|
||||
|
||||
[case_insensitive_dictionary]
|
||||
|
||||
This is a simplified version of the example at
|
||||
[@boost:/libs/unordered/examples/case_insensitive.hpp /libs/unordered/examples/case_insensitive.hpp]
|
||||
which supports other locales and string types.
|
||||
|
||||
[caution
|
||||
Be careful when using the equality (`==`) operator with custom equality
|
||||
predicates, especially if you're using a function pointer. If you compare two
|
||||
containers with different equality predicates then the result is undefined.
|
||||
For most stateless function objects this is impossible - since you can only
|
||||
compare objects with the same equality predicate you know the equality
|
||||
predicates must be equal. But if you're using function pointers or a stateful
|
||||
equality predicate (e.g. boost::function) then you can get into trouble.
|
||||
]
|
||||
|
||||
[h2 Custom Types]
|
||||
|
||||
Similarly, a custom hash function can be used for custom types:
|
||||
|
||||
[import src_code/point1.cpp]
|
||||
[point_example1]
|
||||
|
||||
Since the default hash function is [link hash Boost.Hash],
|
||||
we can [link hash.custom extend it to support the type]
|
||||
so that the hash function doesn't need to be explicitly given:
|
||||
|
||||
[import src_code/point2.cpp]
|
||||
[point_example2]
|
||||
|
||||
See the [link hash.custom Boost.Hash documentation] for more detail on how to
|
||||
do this. Remember that it relies on extensions to the draft standard - so it
|
||||
won't work on other implementations of the unordered associative containers.

[section:intro Introduction]
|
||||
|
||||
For accessing data based on key lookup, the C++ standard library offers `std::set`,
|
||||
`std::map`, `std::multiset` and `std::multimap`. These are generally
|
||||
implemented using balanced binary trees so that lookup time has
|
||||
logarithmic complexity. That is generally okay, but in many cases a
|
||||
__hash-table__ can perform better, as accessing data has constant complexity,
|
||||
on average. The worst case complexity is linear, but that occurs rarely and
|
||||
with some care, can be avoided.
|
||||
|
||||
Also, the existing containers require a 'less than' comparison object
|
||||
to order their elements. For some data types this is impossible to implement
|
||||
or isn't practical. In contrast, a hash table only needs an equality function
|
||||
and a hash function for the key.
|
||||
|
||||
With this in mind, the __tr1__ introduced the unordered associative containers,
|
||||
which are implemented using hash tables, and they have now been added to the
|
||||
__draft__.
|
||||
|
||||
This library supplies an almost complete implementation of the specification in
|
||||
the __draft__.
|
||||
|
||||
`unordered_set` and `unordered_multiset` are defined in the header
|
||||
<[headerref boost/unordered_set.hpp]>
|
||||
|
||||
namespace boost {
|
||||
template <
|
||||
class Key,
|
||||
class Hash = ``[classref boost::hash]``<Key>,
|
||||
class Pred = std::equal_to<Key>,
|
||||
class Alloc = std::allocator<Key> >
|
||||
class ``[classref boost::unordered_set unordered_set]``;
|
||||
|
||||
template<
|
||||
class Key,
|
||||
class Hash = ``[classref boost::hash]``<Key>,
|
||||
class Pred = std::equal_to<Key>,
|
||||
class Alloc = std::allocator<Key> >
|
||||
class ``[classref boost::unordered_multiset unordered_multiset]``;
|
||||
}
|
||||
|
||||
`unordered_map` and `unordered_multimap` are defined in the header
|
||||
<[headerref boost/unordered_map.hpp]>
|
||||
|
||||
namespace boost {
|
||||
template <
|
||||
class Key, class Mapped,
|
||||
class Hash = ``[classref boost::hash]``<Key>,
|
||||
class Pred = std::equal_to<Key>,
|
||||
class Alloc = std::allocator<Key> >
|
||||
class ``[classref boost::unordered_map unordered_map]``;
|
||||
|
||||
template<
|
||||
class Key, class Mapped,
|
||||
class Hash = ``[classref boost::hash]``<Key>,
|
||||
class Pred = std::equal_to<Key>,
|
||||
class Alloc = std::allocator<Key> >
|
||||
class ``[classref boost::unordered_multimap unordered_multimap]``;
|
||||
}
|
||||
|
||||
When using Boost.TR1, these classes are included from `<unordered_set>` and
|
||||
`<unordered_map>`, with the classes added to the `std::tr1` namespace.
|
||||
|
||||
The containers are used in a similar manner to the normal associative
|
||||
containers:
|
||||
|
||||
[import src_code/intro.cpp]
|
||||
[intro_example1_2]
|
||||
|
||||
But since the elements aren't ordered, the output of:
|
||||
|
||||
[intro_example1_3]
|
||||
|
||||
can be in any order. For example, it might be:
|
||||
|
||||
two,2
|
||||
one,1
|
||||
three,3
|
||||
|
||||
To store an object in an unordered associative container requires both an
|
||||
key equality function and a hash function. The default function objects in
|
||||
the standard containers support a few basic types including integer types,
|
||||
floating point types, pointer types, and the standard strings. Since
|
||||
Boost.Unordered uses [classref boost::hash] it also supports some other types,
|
||||
including standard containers. To use any types not supported by these methods
|
||||
you have to [link hash.custom extend Boost.Hash to support the type] or use
|
||||
your own custom equality predicates and hash functions. See the
|
||||
[link unordered.hash_equality Equality Predicates and Hash Functions] section
|
||||
for more details.
|
||||
|
||||
There are other differences, which are listed in the
|
||||
[link unordered.comparison Comparison with Associative Containers] section.

|
||||
|
||||
[section:rationale Implementation Rationale]
|
||||
|
||||
The intent of this library is to implement the unordered
|
||||
containers in the draft standard, so the interface was fixed. But there are
|
||||
still some implementation decisions to make. The priorities are
|
||||
conformance to the standard and portability.
|
||||
|
||||
The [@http://en.wikipedia.org/wiki/Hash_table wikipedia article on hash tables]
|
||||
has a good summary of the implementation issues for hash tables in general.
|
||||
|
||||
[h2 Data Structure]
|
||||
|
||||
By specifying an interface for accessing the buckets of the container the
|
||||
standard pretty much requires that the hash table uses chained addressing.
|
||||
|
||||
It would be conceivable to write a hash table that uses another method. For
|
||||
example, it could use open addressing, and use the lookup chain to act as a
|
||||
bucket but there are a some serious problems with this:
|
||||
|
||||
* The draft standard requires that pointers to elements aren't invalidated, so
|
||||
the elements can't be stored in one array, but will need a layer of
|
||||
indirection instead - losing the efficiency and most of the memory gain,
|
||||
the main advantages of open addressing.
|
||||
|
||||
* Local iterators would be very inefficient and may not be able to
|
||||
meet the complexity requirements.
|
||||
|
||||
* There are also the restrictions on when iterators can be invalidated. Since
|
||||
open addressing degrades badly when there are a high number of collisions the
|
||||
restrictions could prevent a rehash when it's really needed. The maximum load
|
||||
factor could be set to a fairly low value to work around this - but the
|
||||
standard requires that it is initially set to 1.0.
|
||||
|
||||
* And since the standard is written with a eye towards chained
|
||||
addressing, users will be surprised if the performance doesn't reflect that.
|
||||
|
||||
So chained addressing is used.
|
||||
|
||||
For containers with unique keys I store the buckets in a single-linked list.
|
||||
There are other possible data structures (such as a double-linked list)
|
||||
that allow for some operations to be faster (such as erasing and iteration)
|
||||
but the possible gain seems small compared to the extra memory needed.
|
||||
The most commonly used operations (insertion and lookup) would not be improved
|
||||
at all.
|
||||
|
||||
But for containers with equivalent keys a single-linked list can degrade badly
|
||||
when a large number of elements with equivalent keys are inserted. I think it's
|
||||
reasonable to assume that users who choose to use `unordered_multiset` or
|
||||
`unordered_multimap` do so because they are likely to insert elements with
|
||||
equivalent keys. So I have used an alternative data structure that doesn't
|
||||
degrade, at the expense of an extra pointer per node.
|
||||
|
||||
This works by adding storing a circular linked list for each group of equivalent
|
||||
nodes in reverse order. This allows quick navigation to the end of a group (since
|
||||
the first element points to the last) and can be quickly updated when elements
|
||||
are inserted or erased. The main disadvantage of this approach is some hairy code
|
||||
for erasing elements.
|
||||
|
||||
[h2 Number of Buckets]
|
||||
|
||||
There are two popular methods for choosing the number of buckets in a hash
|
||||
table. One is to have a prime number of buckets, another is to use a power
|
||||
of 2.
|
||||
|
||||
Using a prime number of buckets, and choosing a bucket by using the modulus
|
||||
of the hash function's result will usually give a good result. The downside
|
||||
is that the required modulus operation is fairly expensive.
|
||||
|
||||
Using a power of 2 allows for much quicker selection of the bucket
|
||||
to use, but at the expense of loosing the upper bits of the hash value.
|
||||
For some specially designed hash functions it is possible to do this and
|
||||
still get a good result but as the containers can take arbitrary hash
|
||||
functions this can't be relied on.
|
||||
|
||||
To avoid this a transformation could be applied to the hash function, for an
|
||||
example see __wang__. Unfortunately, a transformation like Wang's requires
|
||||
knowledge of the number of bits in the hash value, so it isn't portable enough.
|
||||
This leaves more expensive methods, such as Knuth's Multiplicative Method
|
||||
(mentioned in Wang's article). These don't tend to work as well as taking the
|
||||
modulus of a prime, and the extra computation required might negate
|
||||
efficiency advantage of power of 2 hash tables.
|
||||
|
||||
So, this implementation uses a prime number for the hash table size.
|
||||
|
||||
[h2 Equality operators]
|
||||
|
||||
`operator==` and `operator!=` are not included in the standard, but I've
|
||||
added them as I think they could be useful and can be implemented
|
||||
fairly efficiently. They are specified differently to the other standard
|
||||
containers, comparing keys using the equality predicate rather than
|
||||
`operator==`.
|
||||
|
||||
It's also different to the proposal
|
||||
[@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2944.pdf n2944].
|
||||
which uses the equality operators for the whole of `value_type`. This
|
||||
implementation just uses the key equality function for the key,
|
||||
and `mapped_type`'s equality operator in `unordered_map` and
|
||||
`unordered_multimap` for the mapped part of the element.
|
||||
|
||||
Also, in `unordered_multimap`, the mapped values for a group of elements with
|
||||
equivalent keys are only considered equal if they are in the same order,
|
||||
in n2944 they just need to be a permutation of each other. Since the
|
||||
order of elements with equal keys is now defined to be stable, it seems to me
|
||||
that their order can be considered part of the container's value.
|
||||
|
||||
[h2 Active Issues and Proposals]
|
||||
|
||||
[h3 C++0x allocators]
|
||||
|
||||
Recent drafts have included an overhaul of the allocators, but this was
|
||||
dependent on concepts which are no longer in the standard.
|
||||
[@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2946.pdf n2946]
|
||||
attempts to respecify them without concepts. I'll try to implement this (or
|
||||
an appropriate later version) in a future version of boost, possibly changed
|
||||
a little to accomodate non-C++0x compilers.
|
||||
|
||||
[h3 Swapping containers with unequal allocators]
|
||||
|
||||
It isn't clear how to swap containers when their allocators aren't equal.
|
||||
This is
|
||||
[@http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#431
|
||||
Issue 431: Swapping containers with unequal allocators]. This has been resolved
|
||||
with the new allocator specification, so this should be fixed when
|
||||
support is added.
|
||||
|
||||
[h3 Are insert and erase stable for unordered_multiset and unordered_multimap?]
|
||||
|
||||
It wan't specified if `unordered_multiset` and `unordered_multimap` preserve the order
|
||||
of elements with equivalent keys (i.e. if they're stable under `insert` and `erase`).
|
||||
Since [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2691.pdf
|
||||
n2691] it's been specified that they do and this implementation follows that.

= The Data Structure
|
||||
|
||||
The containers are made up of a number of 'buckets', each of which can contain
|
||||
any number of elements. For example, the following diagram shows an <<unordered_set,unordered_set>> with 7 buckets containing 5 elements, `A`,
|
||||
`B`, `C`, `D` and `E` (this is just for illustration, containers will typically
|
||||
have more buckets).
|
||||
|
||||
image::../diagrams/buckets.png[]
|
||||
|
||||
In order to decide which bucket to place an element in, the container applies
|
||||
the hash function, `Hash`, to the element's key (for `unordered_set` and
|
||||
`unordered_multiset` the key is the whole element, but is referred to as the key
|
||||
so that the same terminology can be used for sets and maps). This returns a
|
||||
value of type `std::size_t`. `std::size_t` has a much greater range of values
|
||||
then the number of buckets, so the container applies another transformation to
|
||||
that value to choose a bucket to place the element in.
|
||||
|
||||
Retrieving the elements for a given key is simple. The same process is applied
|
||||
to the key to find the correct bucket. Then the key is compared with the
|
||||
elements in the bucket to find any elements that match (using the equality
|
||||
predicate `Pred`). If the hash function has worked well the elements will be
|
||||
evenly distributed amongst the buckets so only a small number of elements will
|
||||
need to be examined.
|
||||
|
||||
There is <<hash_equality, more information on hash functions and
|
||||
equality predicates in the next section>>.
|
||||
|
||||
You can see in the diagram that `A` & `D` have been placed in the same bucket.
|
||||
When looking for elements in this bucket up to 2 comparisons are made, making
|
||||
the search slower. This is known as a collision. To keep things fast we try to
|
||||
keep collisions to a minimum.

||||
|
||||
== Controlling the number of buckets
|
||||
|
||||
As more elements are added to an unordered associative container, the number
|
||||
of elements in the buckets will increase causing performance to degrade.
|
||||
To combat this the containers increase the bucket count as elements are inserted.
|
||||
You can also tell the container to change the bucket count (if required) by
|
||||
calling `rehash`.
|
||||
|
||||
The standard leaves a lot of freedom to the implementer to decide how the
|
||||
number of buckets is chosen, but it does make some requirements based on the
|
||||
container's 'load factor', the average number of elements per bucket.
|
||||
Containers also have a 'maximum load factor' which they should try to keep the
|
||||
load factor below.
|
||||
|
||||
You can't control the bucket count directly but there are two ways to
|
||||
influence it:
|
||||
|
||||
* Specify the minimum number of buckets when constructing a container or when calling `rehash`.
|
||||
* Suggest a maximum load factor by calling `max_load_factor`.
|
||||
|
||||
`max_load_factor` doesn't let you set the maximum load factor yourself, it just
|
||||
lets you give a _hint_. And even then, the standard doesn't actually
|
||||
require the container to pay much attention to this value. The only time the
|
||||
load factor is _required_ to be less than the maximum is following a call to
|
||||
`rehash`. But most implementations will try to keep the number of elements
|
||||
below the max load factor, and set the maximum load factor to be the same as
|
||||
or close to the hint - unless your hint is unreasonably small or large.

|Method |Description
|
||||
|
||||
|`X(size_type n)`
|
||||
|Construct an empty container with at least `n` buckets (`X` is the container type).
|
||||
|
||||
|`X(InputIterator i, InputIterator j, size_type n)`
|
||||
|Construct an empty container with at least `n` buckets and insert elements from the range `[i, j)` (`X` is the container type).
|
||||
|
||||
|`float load_factor() const`
|
||||
|The average number of elements per bucket.
|
||||
|
||||
|`float max_load_factor() const`
|
||||
|Returns the current maximum load factor.
|
||||
|
||||
|`float max_load_factor(float z)`
|
||||
|Changes the container's maximum load factor, using `z` as a hint.
|
||||
|
||||
|`void rehash(size_type n)`
|
||||
|Changes the number of buckets so that there at least `n` buckets, and so that the load factor is less than the maximum load factor.
|
||||
|
||||
|===
|
||||
|
||||
== Iterator Invalidation
|
||||
|
||||
It is not specified how member functions other than `rehash` and `reserve` affect
|
||||
the bucket count, although `insert` is only allowed to invalidate iterators
|
||||
when the insertion causes the load factor to be greater than or equal to the
|
||||
maximum load factor. For most implementations this means that `insert` will only
|
||||
change the number of buckets when this happens. While iterators can be
|
||||
invalidated by calls to `insert`, `rehash` and `reserve`, pointers and references to the
|
||||
container's elements are never invalidated.
|
||||
|
||||
In a similar manner to using `reserve` for ``vector``s, it can be a good idea
|
||||
to call `reserve` before inserting a large number of elements. This will get
|
||||
the expensive rehashing out of the way and let you store iterators, safe in
|
||||
the knowledge that they won't be invalidated. If you are inserting `n`
|
||||
elements into container `x`, you could first call:
|
||||
|
||||
```
|
||||
x.reserve(n);
|
||||
```
|
||||
|
||||
Note:: `reserve(n)` reserves space for at least `n` elements, allocating enough buckets
|
||||
so as to not exceed the maximum load factor.
|
||||
+
|
||||
Because the maximum load factor is defined as the number of elements divided by the total
|
||||
number of available buckets, this function is logically equivalent to:
|
||||
+
|
||||
```
|
||||
x.rehash(std::ceil(n / x.max_load_factor()))
|
||||
```
|
||||
+
|
||||
See the <<unordered_map_rehash,reference for more details>> on the `rehash` function.

** Use a simple implementation of `optional` in node handles, so
|
||||
that they're closer to the standard.
|
||||
** Add missing `noexcept` specifications to `swap`, `operator=`
|
||||
and node handles, and change the implementation to match.
|
||||
Using `std::allocator_traits::is_always_equal`, or our own
|
||||
implementation when not available, and
|
||||
`boost::is_nothrow_swappable` in the implementation.
|
||||
* Improved {cpp}20 support:
|
||||
** Use `boost::to_address`, which has the proposed {cpp}20 semantics,
|
||||
rather than the old custom implementation.
|
||||
* Add `element_type` to iterators, so that `std::pointer_traits`
|
||||
will work.
|
||||
* Use `std::piecewise_construct` on recent versions of Visual {cpp},
|
||||
and other uses of the Dinkumware standard library,
|
||||
now using Boost.Predef to check compiler and library versions.
|
||||
* Use `std::iterator_traits` rather than the boost iterator traits
|
||||
in order to remove dependency on Boost.Iterator.
|
||||
* Remove iterators' inheritance from `std::iterator`, which is
|
||||
deprecated in {cpp}17, thanks to Daniela Engert
|
||||
({github-pr-url}/7[PR#7^]).
|
||||
* Stop using `BOOST_DEDUCED_TYPENAME`.
|
||||
* Update some Boost include paths.
|
||||
* Rename some internal methods, and variables.
|
||||
* Various testing improvements.
|
||||
* Miscellaneous internal changes.
|
||||
|
||||
== Release 1.66.0
|
||||
|
||||
* Simpler move construction implementation.
|
||||
* Documentation fixes ({github-pr-url}/6[GitHub #6^]).
|
||||
|
||||
== Release 1.65.0
|
||||
|
||||
* Add deprecated attributes to `quick_erase` and `erase_return_void`.
|
||||
I really will remove them in a future version this time.
|
||||
* Small standards compliance fixes:
|
||||
** `noexpect` specs for `swap` free functions.
|
||||
** Add missing `insert(P&&)` methods.
|
||||
|
||||
== Release 1.64.0
|
||||
|
||||
* Initial support for new {cpp}17 member functions:
|
||||
`insert_or_assign` and `try_emplace` in `unordered_map`,
|
||||
* Initial support for `merge` and `extract`.
|
||||
Does not include transferring nodes between
|
||||
`unordered_map` and `unordered_multimap` or between `unordered_set` and
|
||||
`unordered_multiset` yet. That will hopefully be in the next version of
|
||||
Boost.
|
||||
|
||||
== Release 1.63.0
|
||||
|
||||
* Check hint iterator in `insert`/`emplace_hint`.
|
||||
* Fix some warnings, mostly in the tests.
|
||||
* Manually write out `emplace_args` for small numbers of arguments -
|
||||
should make template error messages a little more bearable.
|
||||
* Remove superfluous use of `boost::forward` in emplace arguments,
|
||||
which fixes emplacing string literals in old versions of Visual {cpp}.
|
||||
* Fix an exception safety issue in assignment. If bucket allocation
|
||||
throws an exception, it can overwrite the hash and equality functions while
|
||||
leaving the existing elements in place. This would mean that the function
|
||||
objects wouldn't match the container elements, so elements might be in the
|
||||
wrong bucket and equivalent elements would be incorrectly handled.
|
||||
* Various reference documentation improvements.
|
||||
* Better allocator support ({svn-ticket-url}/12459[#12459^]).
|
||||
* Make the no argument constructors implicit.
|
||||
* Implement missing allocator aware constructors.
|
||||
* Fix assigning the hash/key equality functions for empty containers.
|
||||
* Remove unary/binary_function from the examples in the documentation.
|
||||
They are removed in {cpp}17.
|
||||
* Support 10 constructor arguments in emplace. It was meant to support up to 10
|
||||
arguments, but an off by one error in the preprocessor code meant it only
|
||||
supported up to 9.
|
||||
|
||||
== Release 1.62.0
|
||||
|
||||
* Remove use of deprecated `boost::iterator`.
|
||||
* Remove `BOOST_NO_STD_DISTANCE` workaround.
|
||||
* Remove `BOOST_UNORDERED_DEPRECATED_EQUALITY` warning.
|
||||
* Simpler implementation of assignment, fixes an exception safety issue
|
||||
for `unordered_multiset` and `unordered_multimap`. Might be a little slower.
|
||||
* Stop using return value SFINAE which some older compilers have issues
|
||||
with.
|
||||
|
||||
== Release 1.58.0
|
||||
|
||||
* Remove unnecessary template parameter from const iterators.
|
||||
* Rename private `iterator` typedef in some iterator classes, as it
|
||||
confuses some traits classes.
|
||||
* Fix move assignment with stateful, propagate_on_container_move_assign
|
||||
allocators ({svn-ticket-url}/10777[#10777^]).
|
||||
* Fix rare exception safety issue in move assignment.
|
||||
* Fix potential overflow when calculating number of buckets to allocate
|
||||
({github-pr-url}/4[GitHub #4^]).
|
||||
|
||||
== Release 1.57.0
|
||||
|
||||
* Fix the `pointer` typedef in iterators ({svn-ticket-url}/10672[#10672^]).
|
||||
* Fix Coverity warning
|
||||
({github-pr-url}/2[GitHub #2^]).
|
||||
|
||||
== Release 1.56.0
|
||||
|
||||
* Fix some shadowed variable warnings ({svn-ticket-url}/9377[#9377^]).
|
||||
* Fix allocator use in documentation ({svn-ticket-url}/9719[#9719^]).
|
||||
* Always use prime number of buckets for integers. Fixes performance
|
||||
regression when inserting consecutive integers, although makes other
|
||||
uses slower ({svn-ticket-url}/9282[#9282^]).
|
||||
* Only construct elements using allocators, as specified in {cpp}11 standard.
|
||||
|
||||
== Release 1.55.0
|
||||
|
||||
* Avoid some warnings ({svn-ticket-url}/8851[#8851^], {svn-ticket-url}/8874[#8874^]).
|
||||
* Avoid exposing some detail functions via. ADL on the iterators.
|
||||
* Follow the standard by only using the allocators' construct and destroy
|
||||
methods to construct and destroy stored elements. Don't use them for internal
|
||||
data like pointers.
|
||||
|
||||
== Release 1.54.0
|
||||
|
||||
* Mark methods specified in standard as `noexpect`. More to come in the next
|
||||
release.
|
||||
* If the hash function and equality predicate are known to both have nothrow
|
||||
move assignment or construction then use them.
|
||||
|
||||
== Release 1.53.0
|
||||
|
||||
* Remove support for the old pre-standard variadic pair constructors, and
|
||||
equality implementation. Both have been deprecated since Boost 1.48.
|
||||
* Remove use of deprecated config macros.
|
||||
* More internal implementation changes, including a much simpler
|
||||
implementation of `erase`.
|
||||
|
||||
== Release 1.52.0
|
||||
|
||||
* Faster assign, which assigns to existing nodes where possible, rather than
|
||||
creating entirely new nodes and copy constructing.
|
||||
* Fixed bug in `erase_range` ({svn-ticket-url}/7471[#7471^]).
|
||||
* Reverted some of the internal changes to how nodes are created, especially
|
||||
for {cpp}11 compilers. 'construct' and 'destroy' should work a little better
|
||||
for {cpp}11 allocators.
|
||||
* Simplified the implementation a bit. Hopefully more robust.
|
||||
|
||||
== Release 1.51.0
|
||||
|
||||
* Fix construction/destruction issue when using a {cpp}11 compiler with a
|
||||
{cpp}03 allocator ({svn-ticket-url}/7100[#7100^]).
|
||||
* Remove a `try..catch` to support compiling without exceptions.
|
||||
* Adjust SFINAE use to try to support g++ 3.4 ({svn-ticket-url}/7175[#7175^]).
|
||||
* Updated to use the new config macros.
|
||||
|
||||
== Release 1.50.0
|
||||
|
||||
* Fix equality for `unordered_multiset` and `unordered_multimap`.
|
||||
* {svn-ticket-url}/6857[Ticket 6857^]:
|
||||
Implement `reserve`.
|
||||
* {svn-ticket-url}/6771[Ticket 6771^]:
|
||||
Avoid gcc's `-Wfloat-equal` warning.
|
||||
* {svn-ticket-url}/6784[Ticket 6784^]:
|
||||
Fix some Sun specific code.
|
||||
* {svn-ticket-url}/6190[Ticket 6190^]:
|
||||
Avoid gcc's `-Wshadow` warning.
|
||||
* {svn-ticket-url}/6905[Ticket 6905^]:
|
||||
Make namespaces in macros compatible with `bcp` custom namespaces.
|
||||
Fixed by Luke Elliott.
|
||||
* Remove some of the smaller prime number of buckets, as they may make
|
||||
collisions quite probable (e.g. multiples of 5 are very common because
|
||||
we used base 10).
|
||||
* On old versions of Visual {cpp}, use the container library's implementation
|
||||
of `allocator_traits`, as it's more likely to work.
|
||||
* On machines with 64 bit std::size_t, use power of 2 buckets, with Thomas
|
||||
Wang's hash function to pick which one to use. As modulus is very slow
|
||||
for 64 bit values.
|
||||
* Some internal changes.
|
||||
|
||||
== Release 1.49.0
|
||||
|
||||
* Fix warning due to accidental odd assignment.
|
||||
* Slightly better error messages.
|
||||
|
||||
== Release 1.48.0 - Major update
|
||||
|
||||
This is major change which has been converted to use Boost.Move's move
|
||||
emulation, and be more compliant with the {cpp}11 standard. See the
|
||||
xref:unordered.adoc#compliance[compliance section] for details.
|
||||
|
||||
The container now meets {cpp}11's complexity requirements, but to do so
|
||||
uses a little more memory. This means that `quick_erase` and
|
||||
`erase_return_void` are no longer required, they'll be removed in a
|
||||
future version.
|
||||
|
||||
{cpp}11 support has resulted in some breaking changes:
|
||||
|
||||
* Equality comparison has been changed to the {cpp}11 specification.
|
||||
In a container with equivalent keys, elements in a group with equal
|
||||
keys used to have to be in the same order to be considered equal,
|
||||
now they can be a permutation of each other. To use the old
|
||||
behavior define the macro `BOOST_UNORDERED_DEPRECATED_EQUALITY`.
|
||||
|
||||
* The behaviour of swap is different when the two containers to be
|
||||
swapped has unequal allocators. It used to allocate new nodes using
|
||||
the appropriate allocators, it now swaps the allocators if
|
||||
the allocator has a member structure `propagate_on_container_swap`,
|
||||
such that `propagate_on_container_swap::value` is true.
|
||||
|
||||
* Allocator's `construct` and `destroy` functions are called with raw
|
||||
pointers, rather than the allocator's `pointer` type.
|
||||
|
||||
* `emplace` used to emulate the variadic pair constructors that
|
||||
appeared in early {cpp}0x drafts. Since they were removed it no
|
||||
longer does so. It does emulate the new `piecewise_construct`
|
||||
pair constructors - only you need to use
|
||||
`boost::piecewise_construct`. To use the old emulation of
|
||||
the variadic constructors define
|
||||
`BOOST_UNORDERED_DEPRECATED_PAIR_CONSTRUCT`.
|
||||
|
||||
== Release 1.45.0
|
||||
|
||||
* Fix a bug when inserting into an `unordered_map` or `unordered_set` using
|
||||
iterators which returns `value_type` by copy.
|
||||
|
||||
== Release 1.43.0
|
||||
|
||||
* {svn-ticket-url}/3966[Ticket 3966^]:
|
||||
`erase_return_void` is now `quick_erase`, which is the
|
||||
http://home.roadrunner.com/~hinnant/issue_review/lwg-active.html#579[
|
||||
current forerunner for resolving the slow erase by iterator^], although
|
||||
there's a strong possibility that this may change in the future. The old
|
||||
method name remains for backwards compatibility but is considered deprecated
|
||||
and will be removed in a future release.
|
||||
* Use Boost.Exception.
|
||||
* Stop using deprecated `BOOST_HAS_*` macros.
|
||||
|
||||
== Release 1.42.0
|
||||
|
||||
* Support instantiating the containers with incomplete value types.
|
||||
* Reduced the number of warnings (mostly in tests).
|
||||
* Improved codegear compatibility.
|
||||
* {svn-ticket-url}/3693[Ticket 3693^]:
|
||||
Add `erase_return_void` as a temporary workaround for the current
|
||||
`erase` which can be inefficient because it has to find the next
|
||||
element to return an iterator.
|
||||
* Add templated find overload for compatible keys.
|
||||
* {svn-ticket-url}/3773[Ticket 3773^]:
|
||||
Add missing `std` qualifier to `ptrdiff_t`.
|
||||
* Some code formatting changes to fit almost all lines into 80 characters.
|
||||
|
||||
== Release 1.41.0 - Major update
|
||||
|
||||
* The original version made heavy use of macros to sidestep some of the older
|
||||
compilers' poor template support. But since I no longer support those
|
||||
compilers and the macro use was starting to become a maintenance burden it
|
||||
has been rewritten to use templates instead of macros for the implementation
|
||||
classes.
|
||||
|
||||
* The container object is now smaller thanks to using `boost::compressed_pair`
|
||||
for EBO and a slightly different function buffer - now using a bool instead
|
||||
of a member pointer.
|
||||
|
||||
* Buckets are allocated lazily which means that constructing an empty container
|
||||
will not allocate any memory.
|
||||
|
||||
== Release 1.40.0
|
||||
|
||||
* {svn-ticket-url}/2975[Ticket 2975^]:
|
||||
Store the prime list as a preprocessor sequence - so that it will always get
|
||||
the length right if it changes again in the future.
|
||||
* {svn-ticket-url}/1978[Ticket 1978^]:
|
||||
Implement `emplace` for all compilers.
|
||||
* {svn-ticket-url}/2908[Ticket 2908^],
|
||||
{svn-ticket-url}/3096[Ticket 3096^]:
|
||||
Some workarounds for old versions of borland, including adding explicit
|
||||
destructors to all containers.
|
||||
* {svn-ticket-url}/3082[Ticket 3082^]:
|
||||
Disable incorrect Visual {cpp} warnings.
|
||||
* Better configuration for {cpp}0x features when the headers aren't available.
|
||||
* Create less buckets by default.
|
||||
|
||||
== Release 1.39.0
|
||||
|
||||
* {svn-ticket-url}/2756[Ticket 2756^]: Avoid a warning
|
||||
on Visual {cpp} 2009.
|
||||
* Some other minor internal changes to the implementation, tests and
|
||||
documentation.
|
||||
* Avoid an unnecessary copy in `operator[]`.
|
||||
* {svn-ticket-url}/2975[Ticket 2975^]: Fix length of
|
||||
prime number list.
|
||||
|
||||
== Release 1.38.0
|
||||
|
||||
* Use link:../../../core/swap.html[`boost::swap`^].
|
||||
* {svn-ticket-url}/2237[Ticket 2237^]:
|
||||
Document that the equality and inequality operators are undefined for two
|
||||
objects if their equality predicates aren't equivalent. Thanks to Daniel
|
||||
Krügler.
|
||||
* {svn-ticket-url}/1710[Ticket 1710^]:
|
||||
Use a larger prime number list. Thanks to Thorsten Ottosen and Hervé
|
||||
Brönnimann.
|
||||
* Use
|
||||
link:../../../type_traits/index.html[aligned storage^] to store the types.
|
||||
This changes the way the allocator is used to construct nodes. It used to
|
||||
construct the node with two calls to the allocator's `construct`
|
||||
method - once for the pointers and once for the value. It now constructs
|
||||
the node with a single call to construct and then constructs the value using
|
||||
in place construction.
|
||||
* Add support for {cpp}0x initializer lists where they're available (currently
|
||||
only g++ 4.4 in {cpp}0x mode).
|
||||
|
||||
== Release 1.37.0
|
||||
|
||||
* Rename overload of `emplace` with hint, to `emplace_hint` as specified in
|
||||
http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2008/n2691.pdf[n2691^].
|
||||
* Provide forwarding headers at `<boost/unordered/unordered_map_fwd.hpp>` and
|
||||
`<boost/unordered/unordered_set_fwd.hpp>`.
|
||||
* Move all the implementation inside `boost/unordered`, to assist
|
||||
modularization and hopefully make it easier to track Release subversion.
|
||||
|
||||
== Release 1.36.0
|
||||
|
||||
First official release.
|
||||
|
||||
* Rearrange the internals.
|
||||
* Move semantics - full support when rvalue references are available, emulated
|
||||
using a cut down version of the Adobe move library when they are not.
|
||||
* Emplace support when rvalue references and variadic template are available.
|
||||
* More efficient node allocation when rvalue references and variadic template
|
||||
are available.
|
||||
* Added equality operators.
|
||||
|
||||
== Boost 1.35.0 Add-on - 31st March 2008
|
||||
|
||||
Unofficial release uploaded to vault, to be used with Boost 1.35.0. Incorporated
|
||||
many of the suggestions from the review.
|
||||
|
||||
* Improved portability thanks to Boost regression testing.
|
||||
* Fix lots of typos, and clearer text in the documentation.
|
||||
* Fix floating point to `std::size_t` conversion when calculating sizes from
|
||||
the max load factor, and use `double` in the calculation for greater accuracy.
|
||||
* Fix some errors in the examples.

|

|
||||
|Keys can be compared using `key_compare` which is accessed by member function `key_comp()`, values can be compared using `value_compare` which is accessed by member function `value_comp()`.
|
||||
|Keys can be hashed using `hasher` which is accessed by member function `hash_function()`, and checked for equality using `key_equal` which is accessed by member function `key_eq()`. There is no function object for compared or hashing values.
|

|

|Constructors have optional extra parameters for the comparison object.
|

|Constructors have optional extra parameters for the initial minimum number of buckets, a hash function and an equality object.
|

|Keys `k1`, `k2` are considered equivalent if `!Compare(k1, k2) && !Compare(k2, k1)`.
|
||||
|Keys `k1`, `k2` are considered equivalent if `Pred(k1, k2)`
|
||||
|
||||
|Member function `lower_bound(k)` and `upper_bound(k)`
|
||||
|No equivalent. Since the elements aren't ordered `lower_bound` and `upper_bound` would be meaningless.
|
||||
|
||||
|`equal_range(k)` returns an empty range at the position that `k` would be inserted if `k` isn't present in the container.
|
||||
|`equal_range(k)` returns a range at the end of the container if `k` isn't present in the container. It can't return a positioned range as `k` could be inserted into multiple place. To find out the bucket that `k` would be inserted into use `bucket(k)`. But remember that an insert can cause the container to rehash - meaning that the element can be inserted into a different bucket.
|
||||
|
||||
|`iterator`, `const_iterator` are of the bidirectional category.
|
||||
|`iterator`, `const_iterator` are of at least the forward category.

|Iterators, pointers and references to the container's elements are never invalidated.

|Iterators iterate through the container in the order defined by the comparison object.
|
||||
|Iterators iterate through the container in an arbitrary order, that can change as elements are inserted, although equivalent elements are always adjacent.
|
||||
|
||||
|No equivalent
|
||||
|Local iterators can be used to iterate through individual buckets. (The order of local iterators and iterators aren't required to have any correspondence.)

|

|
||||
:idprefix: compliance_
|
||||
|
||||
:cpp: C++
|
||||
|
||||
The intent of Boost.Unordered is to implement a close (but imperfect)
|
||||
implementation of the {cpp}17 standard, that will work with {cpp}98 upwards.
|
||||
The wide compatibility does mean some comprimises have to be made.
|
||||
With a compiler and library that fully support {cpp}11, the differences should
|
||||
be minor.
|
||||
|
||||
== Move emulation
|
||||
|
||||
Support for move semantics is implemented using Boost.Move. If rvalue
|
||||
references are available it will use them, but if not it uses a close,
|
||||
but imperfect emulation. On such compilers:
|
||||
|
||||
* Non-copyable objects can be stored in the containers.
|
||||
They can be constructed in place using `emplace`, or if they support
|
||||
Boost.Move, moved into place.
|
||||
* The containers themselves are not movable.
|
||||
* Argument forwarding is not perfect.
|
||||
|
||||
== Use of allocators
|
||||
|
||||
{cpp}11 introduced a new allocator system. It's backwards compatible due to
|
||||
the lax requirements for allocators in the old standard, but might need
|
||||
some changes for allocators which worked with the old versions of the
|
||||
unordered containers.
|
||||
It uses a traits class, `allocator_traits` to handle the allocator
|
||||
adding extra functionality, and making some methods and types optional.
|
||||
During development a stable release of
|
||||
`allocator_traits` wasn't available so an internal partial implementation
|
||||
is always used in this version. Hopefully a future version will use the
|
||||
standard implementation where available.
|
||||
|
||||
The member functions `construct`, `destroy` and `max_size` are now
|
||||
optional, if they're not available a fallback is used.
|
||||
A full implementation of `allocator_traits` requires sophisticated
|
||||
member function detection so that the fallback is used whenever the
|
||||
member function call is not well formed.
|
||||
This requires support for SFINAE expressions, which are available on
|
||||
GCC from version 4.4 and Clang.
|
||||
|
||||
On other compilers, there's just a test to see if the allocator has
|
||||
a member, but no check that it can be called. So rather than using a
|
||||
fallback there will just be a compile error.
|
||||
|
||||
`propagate_on_container_copy_assignment`,
|
||||
`propagate_on_container_move_assignment`,
|
||||
`propagate_on_container_swap` and
|
||||
`select_on_container_copy_construction` are also supported.
|
||||
Due to imperfect move emulation, some assignments might check
|
||||
`propagate_on_container_copy_assignment` on some compilers and
|
||||
`propagate_on_container_move_assignment` on others.
|
||||
|
||||
== Construction/Destruction using allocators
|
||||
|
||||
The following support is required for full use of {cpp}11 style
|
||||
construction/destruction:
|
||||
|
||||
* Variadic templates.
|
||||
* Piecewise construction of `std::pair`.
|
||||
* Either `std::allocator_traits` or expression SFINAE.
|
||||
|
||||
This is detected using Boost.Config. The macro
|
||||
`BOOST_UNORDERED_CXX11_CONSTRUCTION` will be set to 1 if it is found, or 0
|
||||
otherwise.
|
||||
|
||||
When this is the case `allocator_traits::construct` and
|
||||
`allocator_traits::destroy` will always be used, apart from when piecewise
|
||||
constructing a `std::pair` using `boost::tuple` (see <<compliance_pairs,below>>), but that should be easily avoided.
|
||||
|
||||
When support is not available `allocator_traits::construct` and
|
||||
`allocator_traits::destroy` are never called.
|
||||
|
||||
== Pointer Traits
|
||||
|
||||
`pointer_traits` aren't used. Instead, pointer types are obtained from
|
||||
rebound allocators, this can cause problems if the allocator can't be
|
||||
used with incomplete types. If `const_pointer` is not defined in the
|
||||
allocator, `boost::pointer_to_other<pointer, const value_type>::type`
|
||||
is used to obtain a const pointer.
|
||||
|
||||
== Pairs
|
||||
|
||||
Since the containers use `std::pair` they're limited to the version
|
||||
from the current standard library. But since {cpp}11 ``std::pair``'s
|
||||
`piecewise_construct` based constructor is very useful, `emplace`
|
||||
emulates it with a `piecewise_construct` in the `boost::unordered`
|
||||
namespace. So for example, the following will work:
|
||||
|
||||
[source,c++]
|
||||
----
|
||||
boost::unordered_multimap<std::string, std::complex> x;
|
||||
|
||||
x.emplace(
|
||||
boost::unordered::piecewise_construct,
|
||||
boost::make_tuple("key"), boost::make_tuple(1, 2));
|
||||
----
|
||||
|
||||
Older drafts of the standard also supported variadic constructors
|
||||
for `std::pair`, where the first argument would be used for the
|
||||
first part of the pair, and the remaining for the second part.
|
||||
|
||||
== Miscellaneous
|
||||
|
||||
When swapping, `Pred` and `Hash` are not currently swapped by calling
|
||||
`swap`, their copy constructors are used. As a consequence when swapping
|
||||
an exception may be thrown from their copy constructor.
|
||||
|
||||
Variadic constructor arguments for `emplace` are only used when both
|
||||
rvalue references and variadic template parameters are available.
|
||||
Otherwise `emplace` can only take up to 10 constructors arguments.

:idprefix: hash_equality_
|

|
||||
= Equality Predicates and Hash Functions
|
||||
|
||||
While the associative containers use an ordering relation to specify how the
|
||||
elements are stored, the unordered associative containers use an equality
|
||||
predicate and a hash function. For example, <<unordered_map,boost::unordered_map>>
|
||||
is declared as:
|
||||
|
||||
```
|
||||
template <
|
||||
class Key, class Mapped,
|
||||
class Hash = boost::hash<Key>,
|
||||
class Pred = std::equal_to<Key>,
|
||||
class Alloc = std::allocator<std::pair<Key const, Mapped> > >
|
||||
class unordered_map;
|
||||
```
|
||||
|
||||
The hash function comes first as you might want to change the hash function
|
||||
but not the equality predicate. For example, if you wanted to use the
|
||||
http://www.isthe.com/chongo/tech/comp/fnv/[FNV-1 hash^] you could write:
|
||||
|
||||
```
|
||||
boost::unordered_map<std::string, int, hash::fnv_1>
|
||||
dictionary;
|
||||
```
|
||||
|
||||
There is an link:../../examples/fnv1.hpp[implementation of FNV-1^] in the examples directory.
|
||||
|
||||
If you wish to use a different equality function, you will also need to use a matching hash function. For example, to implement a case insensitive dictionary you need to define a case insensitive equality predicate and hash function:
|
||||
|
||||
```
|
||||
struct iequal_to
|
||||
{
|
||||
bool operator()(std::string const& x,
|
||||
std::string const& y) const
|
||||
{
|
||||
return boost::algorithm::iequals(x, y, std::locale());
|
||||
}
|
||||
};
|
||||
|
||||
struct ihash
|
||||
{
|
||||
std::size_t operator()(std::string const& x) const
|
||||
{
|
||||
std::size_t seed = 0;
|
||||
std::locale locale;
|
||||
|
||||
for(std::string::const_iterator it = x.begin();
|
||||
it != x.end(); ++it)
|
||||
{
|
||||
boost::hash_combine(seed, std::toupper(*it, locale));
|
||||
}
|
||||
|
||||
return seed;
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
Which you can then use in a case insensitive dictionary:
|
||||
```
|
||||
boost::unordered_map<std::string, int, ihash, iequal_to>
|
||||
idictionary;
|
||||
```
|
||||
|
||||
This is a simplified version of the example at
|
||||
link:../../examples/case_insensitive.hpp[/libs/unordered/examples/case_insensitive.hpp^] which supports other locales and string types.
|
||||
|
||||
CAUTION: Be careful when using the equality (`==`) operator with custom equality
|
||||
predicates, especially if you're using a function pointer. If you compare two
|
||||
containers with different equality predicates then the result is undefined.
|
||||
For most stateless function objects this is impossible - since you can only
|
||||
compare objects with the same equality predicate you know the equality
|
||||
predicates must be equal. But if you're using function pointers or a stateful
|
||||
equality predicate (e.g. `boost::function`) then you can get into trouble.
|
||||
|
||||
== Custom Types
|
||||
|
||||
Similarly, a custom hash function can be used for custom types:
|
||||
|
||||
```
|
||||
struct point {
|
||||
int x;
|
||||
int y;
|
||||
};
|
||||
|
||||
bool operator==(point const& p1, point const& p2)
|
||||
{
|
||||
return p1.x == p2.x && p1.y == p2.y;
|
||||
}
|
||||
|
||||
struct point_hash
|
||||
{
|
||||
std::size_t operator()(point const& p) const
|
||||
{
|
||||
std::size_t seed = 0;
|
||||
boost::hash_combine(seed, p.x);
|
||||
boost::hash_combine(seed, p.y);
|
||||
return seed;
|
||||
}
|
||||
};
|
||||
|
||||
boost::unordered_multiset<point, point_hash> points;
|
||||
```
|
||||
|
||||
Since the default hash function is link:../../../container_hash/index.html[Boost.Hash^],
|
||||
we can extend it to support the type so that the hash function doesn't need to be explicitly given:
|
||||
|
||||
```
|
||||
struct point {
|
||||
int x;
|
||||
int y;
|
||||
};
|
||||
|
||||
bool operator==(point const& p1, point const& p2)
|
||||
{
|
||||
return p1.x == p2.x && p1.y == p2.y;
|
||||
}
|
||||
|
||||
std::size_t hash_value(point const& p) {
|
||||
std::size_t seed = 0;
|
||||
boost::hash_combine(seed, p.x);
|
||||
boost::hash_combine(seed, p.y);
|
||||
return seed;
|
||||
}
|
||||
|
||||
// Now the default function objects work.
|
||||
boost::unordered_multiset<point> points;
|
||||
```
|
||||
|
||||
See the link:../../../container_hash/index.html[Boost.Hash documentation^] for more detail on how to
|
||||
do this. Remember that it relies on extensions to the standard - so it
|
||||
won't work for other implementations of the unordered associative containers,
|
||||
you'll need to explicitly use Boost.Hash.

:cpp: C++
|
||||
|
||||
For accessing data based on key lookup, the {cpp} standard library offers `std::set`,
|
||||
`std::map`, `std::multiset` and `std::multimap`. These are generally
|
||||
implemented using balanced binary trees so that lookup time has
|
||||
logarithmic complexity. That is generally okay, but in many cases a
|
||||
link:https://en.wikipedia.org/wiki/Hash_table[hash table^] can perform better, as accessing data has constant complexity,
|
||||
on average. The worst case complexity is linear, but that occurs rarely and
|
||||
with some care, can be avoided.
|
||||
|
||||
Also, the existing containers require a 'less than' comparison object
|
||||
to order their elements. For some data types this is impossible to implement
|
||||
or isn't practical. In contrast, a hash table only needs an equality function
|
||||
and a hash function for the key.
|
||||
|
||||
With this in mind, unordered associative containers were added to the {cpp}
|
||||
standard. This is an implementation of the containers described in {cpp}11,
|
||||
with some <<compliance,deviations from the standard>> in
|
||||
order to work with non-{cpp}11 compilers and libraries.

To store an object in an unordered associative container requires both a
|
||||
key equality function and a hash function. The default function objects in
|
||||
the standard containers support a few basic types including integer types,
|
||||
floating point types, pointer types, and the standard strings. Since
|
||||
Boost.Unordered uses link:../../../container_hash/index.html[boost::hash^] it also supports some other types,
|
||||
including standard containers. To use any types not supported by these methods
|
||||
you have to extend Boost.Hash to support the type or use
|
||||
your own custom equality predicates and hash functions. See the
|
||||
<<hash_equality,Equality Predicates and Hash Functions>> section
|
||||
for more details.
|

There are other differences, which are listed in the

:idprefix: rationale_
|

|
||||
= Implementation Rationale
|
||||
|
||||
The intent of this library is to implement the unordered
|
||||
containers in the standard, so the interface was fixed. But there are
|
||||
still some implementation decisions to make. The priorities are
|
||||
conformance to the standard and portability.
|
||||
|
||||
The http://en.wikipedia.org/wiki/Hash_table[Wikipedia article on hash tables^]
|
||||
has a good summary of the implementation issues for hash tables in general.
|
||||
|
||||
== Data Structure
|
||||
|
||||
By specifying an interface for accessing the buckets of the container the
|
||||
standard pretty much requires that the hash table uses chained addressing.
|
||||
|
||||
It would be conceivable to write a hash table that uses another method. For
|
||||
example, it could use open addressing, and use the lookup chain to act as a
|
||||
bucket but there are some serious problems with this:
|
||||
|
||||
* The standard requires that pointers to elements aren't invalidated, so
|
||||
the elements can't be stored in one array, but will need a layer of
|
||||
indirection instead - losing the efficiency and most of the memory gain,
|
||||
the main advantages of open addressing.
|
||||
* Local iterators would be very inefficient and may not be able to
|
||||
meet the complexity requirements.
|
||||
* There are also the restrictions on when iterators can be invalidated. Since
|
||||
open addressing degrades badly when there are a high number of collisions the
|
||||
restrictions could prevent a rehash when it's really needed. The maximum load
|
||||
factor could be set to a fairly low value to work around this - but the
|
||||
standard requires that it is initially set to 1.0.
|
||||
* And since the standard is written with a eye towards chained
|
||||
addressing, users will be surprised if the performance doesn't reflect that.
|
||||
|
||||
So chained addressing is used.
|
||||
|
||||
== Number of Buckets
|
||||
|
||||
There are two popular methods for choosing the number of buckets in a hash
|
||||
table. One is to have a prime number of buckets, another is to use a power
|
||||
of 2.
|
||||
|
||||
Using a prime number of buckets, and choosing a bucket by using the modulus
|
||||
of the hash function's result will usually give a good result. The downside
|
||||
is that the required modulus operation is fairly expensive. This is what the
|
||||
containers used to do in most cases.
|
||||
|
||||
Using a power of 2 allows for much quicker selection of the bucket to use,
|
||||
but at the expense of losing the upper bits of the hash value. For some
|
||||
specially designed hash functions it is possible to do this and still get a
|
||||
good result but as the containers can take arbitrary hash functions this can't
|
||||
be relied on.
|
||||
|
||||
To avoid this a transformation could be applied to the hash function, for an
|
||||
example see
|
||||
http://web.archive.org/web/20121102023700/http://www.concentric.net/~Ttwang/tech/inthash.htm[Thomas Wang's article on integer hash functions^].
|
||||
Unfortunately, a transformation like Wang's requires knowledge of the number

of bits in the hash value, so it was only used when `size_t` was 64 bit.
|
||||
|
||||
Since release 1.79.0, https://en.wikipedia.org/wiki/Hash_function#Fibonacci_hashing[Fibonacci hashing]
|
||||
is used instead. With this implementation, the bucket number is determined
|
||||
by using `(h * m) >> (w - k)`, where `h` is the hash value, `m` is the golden
|
||||
ratio multiplied by `2^w`, `w` is the word size (32 or 64), and `2^k` is the
|
||||
number of buckets. This provides a good compromise between speed and
|
||||
distribution.

This test fail because it's using unordered's internal

It normally uses the one from Boost.Container by default.
