2011-01-14 23:06:14 +00:00
Bryce Adelstein-Lelbach 0c0a866f07 Replacing the use of <iomanip> with <boost/detail/iomanip.hpp> across Boost.
On Linux, GNU's libstdc++, which is the default stdlib for icc and clang,
cannot parse the <iomanip> header in version 4.5+ (which thankfully neither
compiler advises the use of yet), as it's original C++98-friendly
implementation has been replaced with a gnu++0x implementation.
<boost/detail/iomanip.hpp> is a portable implementation of <iomanip>, providing
boost::detail::setfill, boost::detail::setbase, boost::detail::setw,
boost::detail::setprecision, boost::detail::setiosflags and
boost::detail::resetiosflags.

[section Description and Rationale]
Boost.Algorithm is a collection of general purpose algorithms. While Boost contains many libraries of data structures, there is no single library for general purpose algorithms. Even though the algorithms are generally useful, many tend to be thought of as "too small" for Boost.
An implementation of Boyer-Moore searching, for example, might take a developer a week or so to implement, including test cases and documentation. However, scheduling a review to include that code into Boost might take several months, and run into resistance because "it is too small". Nevertheless, a library of tested, reviewed, documented algorithms can make the developer's life much easier, and that is the purpose of this library.
[heading Future plans]
I will be soliciting submissions from other developers, as well as looking through the literature for existing algorithms to include. The Adobe Source Library, for example, contains many useful algorithms that already have documentation and test cases. Knuth's _The Art of Computer Programming_ is chock-full of algorithm descriptions, too.
My goal is to run regular algorithm reviews, similar to the Boost library review process, but with smaller chunks of code.
[heading Dependencies]
Boost.Algorithm uses Boost.Range, Boost.Assert, Boost.Array, Boost.TypeTraits, and Boost.StaticAssert.
[heading Acknowledgements]
Thanks to all the people who have reviewed this library and made suggestions for improvements. Steven Watanabe and Sean Parent, in particular, have provided a great deal of help.

The header file 'boost/algorithm/cxx11/all_of.hpp' contains four variants of a single algorithm, `all_of`. The algorithm tests all the elements of a sequence and returns true if they all share a property.
The routine `all_of` takes a sequence and a predicate. It will return true if the predicate returns true when applied to every element in the sequence.
The routine `all_of_equal` takes a sequence and a value. It will return true if every element in the sequence compares equal to the passed in value.
Both routines come in two forms; the first one takes two iterators to define the range. The second form takes a single range parameter, and uses Boost.Range to traverse it.
[heading interface]
The function `all_of` returns true if the predicate returns true for every item in the sequence. There are two versions; one takes two iterators, and the other takes a range.
``
namespace boost { namespace algorithm {
template<typename InputIterator, typename Predicate>
bool all_of ( InputIterator first, InputIterator last, Predicate p );
template<typename Range, typename Predicate>
bool all_of ( const Range &r, Predicate p );
}}
``
The function `all_of_equal` is similar to `all_of`, but instead of taking a predicate to test the elements of the sequence, it takes a value to compare against.
``
namespace boost { namespace algorithm {
template<typename InputIterator, typename V>
bool all_of_equal ( InputIterator first, InputIterator last, V const &val );
template<typename Range, typename V>
bool all_of_equal ( const Range &r, V const &val );
}}
``
[heading Examples]
Given the container `c` containing `{ 0, 1, 2, 3, 14, 15 }`, then
``
bool isOdd ( int i ) { return i % 2 == 1; }
bool lessThan10 ( int i ) { return i < 10; }
using boost::algorithm;
all_of ( c, isOdd ) --> false
all_of ( c.begin (), c.end (), lessThan10 ) --> false
all_of ( c.begin (), c.begin () + 3, lessThan10 ) --> true
all_of ( c.end (), c.end (), isOdd ) --> true // empty range
all_of_equal ( c, 3 ) --> false
all_of_equal ( c.begin () + 3, c.begin () + 4, 3 ) --> true
all_of_equal ( c.begin (), c.begin (), 99 ) --> true // empty range
``
[heading Iterator Requirements]
`all_of` and `all_of_equal` work on all iterators except output iterators.
[heading Complexity]
All of the variants of `all_of` and `all_of_equal` run in ['O(N)] (linear) time; that is, they compare against each element in the list once. If any of the comparisons fail, the algorithm will terminate immediately, without examining the remaining members of the sequence.
[heading Exception Safety]
All of the variants of `all_of` and `all_of_equal` take their parameters by value or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
[heading Notes]
* The routine `all_of` is part of the C++11 standard. When compiled using a C++11 implementation, the implementation from the standard library will be used.
* `all_of` and `all_of_equal` both return true for empty ranges, no matter what is passed to test against. When there are no items in the sequence to test, they all satisfy the condition to be tested against.
* The second parameter to `all_of_value` is a template parameter, rather than deduced from the first parameter (`std::iterator_traits<InputIterator>::value_type`) because that allows more flexibility for callers, and takes advantage of built-in comparisons for the type that is pointed to by the iterator. The function is defined to return true if, for all elements in the sequence, the expression `*iter == val` evaluates to true (where `iter` is an iterator to each element in the sequence)

[heading Overview]
The header file 'boyer_moore.hpp' contains an an implementation of the Boyer-Moore algorithm for searching sequences of values.
The BoyerMoore string search algorithm is a particularly efficient string searching algorithm, and it has been the standard benchmark for the practical string search literature. The Boyer-Moore algorithm was invented by Bob Boyer and J. Strother Moore, and published in the October 1977 issue of the Communications of the ACM , and a copy of that article is available at [@http://www.cs.utexas.edu/~moore/publications/fstrpos.pdf].
The Boyer-Moore algorithm uses two precomputed tables to give better performance than a naive search. These tables depend on the pattern being searched for, and give the Boyer-Moore algorithm larger a memory footprint and startup costs than a simpler algorithm, but these costs are recovered quickly during the searching process, especially if the pattern is longer than a few elements.
However, the Boyer-Moore algorithm cannot be used with comparison predicates like `std::search`.
Nomenclature: I refer to the sequence being searched for as the "pattern", and the sequence being searched in as the "corpus".
For flexibility, the Boyer-Moore algorithm has has two interfaces; an object-based interface and a procedural one. The object-based interface builds the tables in the constructor, and uses operator () to perform the search. The procedural interface builds the table and does the search all in one step. If you are going to be searching for the same pattern in multiple corpora, then you should use the object interface, and only build the tables once.
Here is the object interface:
``
template <typename patIter>
class boyer_moore {
public:
boyer_moore ( patIter first, patIter last );
~boyer_moore ();
template <typename corpusIter>
corpusIter operator () ( corpusIter corpus_first, corpusIter corpus_last );
};
``
and here is the corresponding procedural interface:
``
template <typename patIter, typename corpusIter>
corpusIter boyer_moore_search (
corpusIter corpus_first, corpusIter corpus_last,
patIter pat_first, patIter pat_last );
``
Each of the functions is passed two pairs of iterators. The first two define the corpus and the second two define the pattern. Note that the two pairs need not be of the same type, but they do need to "point" at the same type. In other words, `patIter::value_type` and `curpusIter::value_type` need to be the same type.
The return value of the function is an iterator pointing to the start of the pattern in the corpus. If the pattern is not found, it returns the end of the corpus (`corpus_last`).
[heading Performance]
The execution time of the Boyer-Moore algorithm, while still linear in the size of the string being searched, can have a significantly lower constant factor than many other search algorithms: it doesn't need to check every character of the string to be searched, but rather skips over some of them. Generally the algorithm gets faster as the pattern being searched for becomes longer. Its efficiency derives from the fact that with each unsuccessful attempt to find a match between the search string and the text it is searching, it uses the information gained from that attempt to rule out as many positions of the text as possible where the string cannot match.
[heading Memory Use]
The algorithm allocates two internal tables. The first one is proportional to the length of the pattern; the second one has one entry for each member of the "alphabet" in the pattern. For (8-bit) character types, this table contains 256 entries.
[heading Complexity]
The worst-case performance to find a pattern in the corpus is ['O(N)] (linear) time; that is, proportional to the length of the corpus being searched. In general, the search is sub-linear; not every entry in the corpus need be checked.
[heading Exception Safety]
Both the object-oriented and procedural versions of the Boyer-Moore algorithm take their parameters by value and do not use any information other than what is passed in. Therefore, both interfaces provide the strong exception guarantee.
[heading Notes]
* When using the object-based interface, the pattern must remain unchanged for during the searches; i.e, from the time the object is constructed until the final call to operator () returns.
* The Boyer-Moore algorithm requires random-access iterators for both the pattern and the corpus.
[heading Customization points]
The Boyer-Moore object takes a traits template parameter which enables the caller to customize how one of the precomputed tables is stored. This table, called the skip table, contains (logically) one entry for every possible value that the pattern can contain. When searching 8-bit character data, this table contains 256 elements. The traits class defines the table to be used.
The default traits class uses a `boost::array` for small 'alphabets' and a `tr1::unordered_map` for larger ones. The array-based skip table gives excellent performance, but could be prohibitively large when the "alphabet" of elements to be searched grows. The unordered_map based version only grows as the number of unique elements in the pattern, but makes many more heap allocations, and gives slower lookup performance.
To use a different skip table, you should define your own skip table object and your own traits class, and use them to instantiate the Boyer-Moore object. The interface to these objects is described TBD.

The header file clamp.hpp contains two functions for "clamping" a value between a pair of boundary values.
[heading clamp]
The function `clamp (v, lo, hi)` returns:
* lo if v < lo
* hi if hi < v
* otherwise, v
Note: using `clamp` with floating point numbers may give unexpected results if one of the values is `NaN`.
There is also a version that allows the caller to specify a comparison predicate to use instead of `operator <`.

V clamp ( V val, V lo, V hi );
template<typename V, typename Pred>
V clamp ( V val, V lo, V hi, Pred p );
``
The following code: ``
int foo = 23;
foo = clamp ( foo, 1, 10 );
``
will leave `foo` with a value of 10
Complexity:
`clamp` will make either one or two calls to the comparison predicate before returning one of the three parameters.
[heading clamp_range]
There are also four range-based versions of clamp, that apply clamping to a series of values. You could write them yourself with std::transform and bind, like this: `std::transform ( first, last, out, bind ( clamp ( _1, lo, hi )))`, but they are provided here for your convenience.
``
template<typename InputIterator, typename OutputIterator>

typename std::iterator_traits<InputIterator>::value_type lo,
typename std::iterator_traits<InputIterator>::value_type hi );

The header file `'boost/algorithm/hex.hpp'` contains three variants each of two algorithms, `hex` and `unhex`. They are inverse algorithms; that is, one undoes the effort of the other. `hex` takes a sequence of values, and turns them into hexadecimal characters. `unhex` takes a sequence of hexadecimal characters, and outputs a sequence of values.
`hex` and `unhex` come from MySQL, where they are used in database queries and stored procedures.
[heading interface]
The function `hex` takes a sequence of values and writes hexadecimal characters. There are three different interfaces, differing only in how the input sequence is specified.
The first one takes an iterator pair. The second one takes a pointer to the start of a zero-terminated sequence, such as a c string, and the third takes a range as defined by the Boost.Range library.
``
template <typename InputIterator, typename OutputIterator>
OutputIterator hex ( InputIterator first, InputIterator last, OutputIterator out );
template <typename T, typename OutputIterator>
OutputIterator hex ( const T *ptr, OutputIterator out );
template <typename Range, typename OutputIterator>
OutputIterator hex ( const Range &r, OutputIterator out );
``
`hex` writes only values in the range '0'..'9' and 'A'..'F', but is not limited to character output. The output iterator could refer to a wstring, or a vector of integers, or any other integral type.
The function `unhex` takes the output of `hex` and turns it back into a sequence of values.
The input parameters for the different variations of `unhex` are the same as `hex`.
``
template <typename InputIterator, typename OutputIterator>
OutputIterator unhex ( InputIterator first, InputIterator last, OutputIterator out );
template <typename T, typename OutputIterator>
OutputIterator unhex ( const T *ptr, OutputIterator out );
template <typename Range, typename OutputIterator>
OutputIterator unhex ( const Range &r, OutputIterator out );
``
[heading Error Handling]
The header 'hex.hpp' defines three exception classes:
``
struct hex_decode_error: virtual boost::exception, virtual std::exception {};
struct not_enough_input : public hex_decode_error;
struct non_hex_input : public hex_decode_error;
``
If the input to `unhex` does not contain an "even number" of hex digits, then an exception of type `boost::algorithm::not_enough_input` is thrown.
If the input to `unhex` contains any non-hexadecimal characters, then an exception of type `boost::algorithm::non_hex_input` is thrown.
If you want to catch all the decoding errors, you can catch exceptions of type `boost::algorithm::hex_decode_error`.
[heading Examples]
Assuming that `out` is an iterator that accepts `char` values, and `wout` accepts `wchar_t` values (and that sizeof ( wchar_t ) == 2)
``
hex ( "abcde", out ) --> "616263646566"
hex ( "32", out ) --> "3332"
hex ( "abcde", wout ) --> "006100620063006400650066"
hex ( "32", wout ) --> "00330032"
unhex ( "616263646566", out ) --> "abcde"
unhex ( "3332", out ) --> "32"
unhex ( "616263646566", wout ) --> "\6162\6364\6566" ( i.e, a 3 character string )
unhex ( "3332", wout ) --> "\3233" ( U+3332, SQUARE HUARADDO )
unhex ( "3", out ) --> Error - not enough input
unhex ( "32", wout ) --> Error - not enough input
unhex ( "ACEG", out ) --> Error - non-hex input
``
[heading Iterator Requirements]
`hex` and `unhex` work on all iterator types.
[heading Complexity]
All of the variants of `hex` and `unhex` run in ['O(N)] (linear) time; that is, that is, they process each element in the input sequence once.
[heading Exception Safety]
All of the variants of `hex` and `unhex` take their parameters by value or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee. However, when working on input iterators, if an exception is thrown, the input iterators will not be reset to their original values (i.e, the characters read from the iterator cannot be un-read)
[heading Notes]
* `hex` and `unhex` both do nothing when passed empty ranges.

The header file 'is_partitioned.hpp' contains two variants of a single algorithm, `is_partitioned`. The algorithm tests to see if a sequence is partitioned according to a predicate; in other words, all the items in the sequence that satisfy the predicate are at the beginning of the sequence.
The routine `is_partitioned` takes a sequence and a predicate. It returns true if the sequence is partitioned according to the predicate.
`is_partitioned` come in two forms; the first one takes two iterators to define the range. The second form takes a single range parameter, and uses Boost.Range to traverse it.
[heading interface]
The function `is_partitioned` returns true the items in the sequence are separated according to their ability to satisfy the predicate. There are two versions; one takes two iterators, and the other takes a range.
``
template<typename InputIterator, typename Predicate>
bool is_partitioned ( InputIterator first, InputIterator last, Predicate p );
template<typename Range, typename Predicate>
bool is_partitioned ( const Range &r, Predicate p );
``
[heading Examples]
Given the container `c` containing `{ 0, 1, 2, 3, 14, 15 }`, then
``
bool isOdd ( int i ) { return i % 2 == 1; }
bool lessThan10 ( int i ) { return i < 10; }
is_partitioned ( c, isOdd ) --> false
is_partitioned ( c, lessThan10 ) --> true
is_partitioned ( c.begin (), c.end (), lessThan10 ) --> true
is_partitioned ( c.begin (), c.begin () + 3, lessThan10 ) --> true
is_partitioned ( c.end (), c.end (), isOdd ) --> true // empty range
``
[heading Iterator Requirements]
`is_partitioned` works on all iterators except output iterators.
[heading Complexity]
Both of the variants of `is_partitioned` run in ['O(N)] (linear) time; that is, they compare against each element in the list once. If the sequence is found to be not partitioned at any point, the routine will terminate immediately, without examining the rest of the elements.
[heading Exception Safety]
Both of the variants of `is_partitioned` take their parameters by value or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
[heading Notes]
* The iterator-based version of the routine `is_partitioned` is part of the C++11 standard. When compiled using a C++11 implementation, the implementation from the standard library will be used.
* `is_partitioned` returns true for empty ranges, no matter what predicate is passed to test against.

The header file 'boost/algorithm/cxx11/none_of.hpp' contains four variants of a single algorithm, `none_of`. The algorithm tests all the elements of a sequence and returns true if they none of them share a property.
The routine `none_of` takes a sequence and a predicate. It will return true if the predicate returns false when applied to every element in the sequence.
The routine `none_of_equal` takes a sequence and a value. It will return true if none of the elements in the sequence compare equal to the passed in value.
Both routines come in two forms; the first one takes two iterators to define the range. The second form takes a single range parameter, and uses Boost.Range to traverse it.

The header file `<boost/algorithm/cxx11/is_sorted.hpp>` contains functions for determining if a sequence is ordered.
[heading is_sorted]
The function `is_sorted(sequence)` determines whether or not a sequence is completely sorted according so some criteria. If no comparison predicate is specified, then std::less_equal is used (i.e, the test is to see if the sequence is non-decreasing)
``
namespace boost { namespace algorithm {
template <typename Iterator, typename Pred>
bool is_sorted ( Iterator first, Iterator last, Pred p );
template <typename Iterator>
bool is_sorted ( Iterator first, Iterator last );
template <typename Range, typename Pred>
bool is_sorted ( const Range &r, Pred p );
template <typename Range>
bool is_sorted ( const Range &r );
}}
``
Iterator requirements: The `is_sorted` functions will work on all kinds of iterators (except output iterators).
[heading is_sorted_until]
The function `is_sorted_until(sequence, predicate)` compares each sequential pair of elements in the sequence, checking if they satisfy the predicate. it returns the first element of the sequence that does not satisfy the predicate with its' predecessor. In short, it returns the element in the sequence that is "out of order". If all adjacent pairs satisfy the predicate, then it will return one past the last element of the sequence.
``
namespace boost { namespace algorithm {
template <typename ForwardIterator, typename Pred>
FI is_sorted_until ( ForwardIterator first, ForwardIterator last, Pred p );
template <typename ForwardIterator>
ForwardIterator is_sorted_until ( ForwardIterator first, ForwardIterator last );
template <typename Range, typename Pred>
typename boost::range_iterator<const R>::type is_sorted_until ( const Range &r, Pred p );
template <typename Range>
typename boost::range_iterator<const R>::type is_sorted_until ( const Range &r );
}}
``
Iterator requirements: The `is_sorted_until` functions will work on forward iterators or better. Since they have to return a place in the input sequence, input iterators will not suffice.
Complexity:
`is_sorted_until` will make at most ['N-1] calls to the predicate (given a sequence of length ['N]).
Examples:
Given the sequence `{ 1, 2, 3, 4, 5, 3 }`, `is_sorted_until ( beg, end, std::less<int>())` would return an iterator pointing at the second `3`.
Given the sequence `{ 1, 2, 3, 4, 5, 9 }`, `is_sorted_until ( beg, end, std::less<int>())` would return `end`.
There are also a set of "wrapper functions" for is_ordered which make it easy to see if an entire sequence is ordered. These functions return a boolean indicating success or failure rather than an iterator to where the out of order items were found.
To test if a sequence is increasing (each element at least as large as the preceeding one):
``
namespace boost { namespace algorithm {
template <typename Iterator>
bool is_increasing ( Iterator first, Iterator last );
template <typename R>
bool is_increasing ( const R &range );
}}
``
To test if a sequence is decreasing (each element no larger than the preceeding one):
``
namespace boost { namespace algorithm {
template <typename Iterator>
bool is_decreasing ( Iterator first, Iterator last );
template <typename R>
bool is_decreasing ( const R &range );
}}
``
To test if a sequence is strictly increasing (each element larger than the preceeding one):
``
namespace boost { namespace algorithm {
template <typename Iterator>
bool is_strictly_increasing ( Iterator first, Iterator last );
template <typename R>
bool is_strictly_increasing ( const R &range );
}}
``
To test if a sequence is strictly decreasing (each element smaller than the preceeding one):
``
namespace boost { namespace algorithm {
template <typename Iterator>
bool is_strictly_decreasing ( Iterator first, Iterator last );
template <typename R>
bool is_strictly_decreasing ( const R &range );
}}
``
Complexity:
Each of these calls is just a thin wrapper over `is_sorted`, so they have the same complexity as `is_sorted`.
[heading Notes]
* The routines `is_sorted` and `is_sorted_until` are part of the C++11 standard. When compiled using a C++11 implementation, the implementation from the standard library will be used.
* `is_sorted` and `is_sorted_until` both return true for empty ranges and ranges of length one.

The header file 'partition_point.hpp' contains two variants of a single algorithm, `partition_point`. Given a partitioned sequence and a predicate, the algorithm finds the partition point; i.e, the first element in the sequence that does not satisfy the predicate.
The routine `partition_point` takes a partitioned sequence and a predicate. It returns an iterator which 'points to' the first element in the sequence that does not satisfy the predicate. If all the items in the sequence satisfy the predicate, then it returns one past the final element in the sequence.
`partition_point` come in two forms; the first one takes two iterators to define the range. The second form takes a single range parameter, and uses Boost.Range to traverse it.
[heading interface]
There are two versions; one takes two iterators, and the other takes a range.
``
template<typename ForwardIterator, typename Predicate>
ForwardIterator partition_point ( ForwardIterator first, ForwardIterator last, Predicate p );
template<typename Range, typename Predicate>
boost::range_iterator<Range> partition_point ( const Range &r, Predicate p );
``
[heading Examples]
Given the container `c` containing `{ 0, 1, 2, 3, 14, 15 }`, then
``
bool lessThan10 ( int i ) { return i < 10; }
bool isOdd ( int i ) { return i % 2 == 1; }
partition_point ( c, lessThan10 ) --> c.begin () + 4 (pointing at 14)
partition_point ( c.begin (), c.end (), lessThan10 ) --> c.begin () + 4 (pointing at 14)
partition_point ( c.begin (), c.begin () + 3, lessThan10 ) -> c.begin () + 3 (end)
partition_point ( c.end (), c.end (), isOdd ) --> c.end () // empty range
``
[heading Iterator Requirements]
`partition_point` requires forward iterators or better; it will not work on input iterators or output iterators.
[heading Complexity]
Both of the variants of `partition_point` run in ['O( log (N))] (logarithmic) time; that is, the predicate will be will be applied approximately ['log(N)] times. To do this, however, the algorithm needs to know the size of the sequence. For forward and bidirectional iterators, calculating the size of the sequence is an ['O(N)] operation.
[heading Exception Safety]
Both of the variants of `partition_point` take their parameters by value or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
[heading Notes]
* The iterator-based version of the routine `partition_point` is part of the C++11 standard. When compiled using a C++11 implementation, the implementation from the standard library will be used.
* For empty ranges, the partition point is the end of the range.

1. these should really only work on integral types. (see the >> and << operations)

2. The 'value_type_or_char' struct is really a hack.

A templated version of the boyer-moore searching algorithm.
References:
http://www.cs.utexas.edu/users/moore/best-ideas/string-searching/
http://www.cs.utexas.edu/~moore/publications/fstrpos.pdf
Explanations: boostinspect:noascii (test tool complains)
http://en.wikipedia.org/wiki/BoyerMoore_string_search_algorithm
http://www.movsd.com/bm.htm
http://www.cs.ucdavis.edu/~gusfield/cs224f09/bnotes.pdf
The Boyer-Moore search algorithm uses two tables, a "bad character" table
to tell how far to skip ahead when it hits a character that is not in the pattern,
and a "good character" table to tell how far to skip ahead when it hits a
mismatch on a character that _is_ in the pattern.
Requirements:
* Random access iterators
* The two iterator types (patIter and corpusIter) must
"point to" the same underlying type and be comparable.
* Additional requirements may be imposed but the skip table, such as:
** Numeric type (array-based skip table)
** Hashable type (map-based skip table)

Traits defined in this header are used by various algorithms to achieve
better performance for specific containers.
Traits provide fail-safe defaults. If a container supports some of these
features, it is possible to specialize the specific trait for this container.
For lacking compilers, it is possible of define an override for a specific tester
function.
Due to a language restriction, it is not currently possible to define specializations for
stl containers without including the corresponding header. To decrease the overhead
needed by this inclusion, user can selectively include a specialization
header for a specific container. They are located in boost/algorithm/string/stl
directory. Alternatively she can include boost/algorithm/string/std_collection_traits.hpp
header which contains specializations for all stl containers.

Defines basic split algorithms.
Split algorithms can be used to divide a string

output container.

of the matches (in a compatible structure like std::string) or
