/*!
Collection traits provide uniform access to different types of
collections. This functionality allows to write generic algorithms
which work with several different kinds of collections.
Currently following collection types are supported:
- containers with STL compatible container interface ( see ContainerConcept )
( i.e. \c std::vector<>, \c std::list<>, \c std::string<> ... )
- c-style array
( \c char[10], \c int[15] ... )
- null-terminated c-strings
( \c char*, \c wchar_T* )
- std::pair of iterators
( i.e \c std::pair<vector<int>::iterator,vector<int>::iterator> )
Collection traits provide an external collection interface operations.
All are accessible using free-standing functions.
The following operations are supported:
- \c size()
- \c empty()
- \c begin()
- \c end()
Container traits have somewhat limited functionality on compilers not
supporting partial template specialization and partial template ordering.

An \c iterator_range delimits a range in a sequence by beginning and ending iterators.
An iterator_range can be passed to an algorithm which requires a sequence as an input.

but can also be used on iterator_ranges:
\code
boost::tolower( find( s, "UPPERCASE STRING" ) );

Many algorithms working with sequences take a pair of iterators,
delimiting a working range, as arguments. The \c iterator_range class is an
encapsulation of a range identified by a pair of iterators.
It provides a collection interface,

<h1>
Minmax_element Performance</h1></center>
<h3>
<a NAME="Performance"></a><b>About performance</b></h3>
Of course, there are many factors that affect the performance of an algorithm.
The number of comparison is only one, but also branch prediction, pipelining,
locality of reference (affects cache efficiency), etc. In practice,
we observe that when the iterator type is a pointer,
<tt>boost::minmax_element</tt>
is only a tad slower than
<tt>std::min_element</tt>, and is even faster
than
<tt>boost::first_min_last_max_element</tt>! This is even more true
for slower iterators (<tt>list&lt;>::iterator</tt> or
<tt>map&lt;>iterator</tt>
for instance). The following experiments were conducted on a Pentium III
500 Mhz running Linux and compiled with g++, version 2.95.2, flags -O3.
In the tables, we use different distributions: <i>Identical</i> means that
all the elements are identical, <i>2-valued</i> means that we replace the
second half of the identical elements by a distinct element, <i>increasing</i>
means that all the elements are distinct and in increasing order, <i>decrea</i>sing
is the reverse, and <i>random</i> is produced by random_shuffle.
<br>
The program that created these tables is included in the distribution,
under <a href="../example/minmax_timer.cpp">minmax_timer.cpp</a>

<h3>
Motivation</h3>
<p>The minmax library is composed of two headers, <a
href="../../../boost/algorithm/minmax.hpp">&lt;boost/algorithm/minmax.hpp></a>
and <a
href="../../../boost/algorithm/minmax_element.hpp">&lt;boost/algorithm/minmax_element.hpp></a>.
(See <a href="#two_headers">rationale</a>.)
The problem solved by this library is that simultaneous min and max
computation requires
only one comparison, but using <tt>std::min</tt> and <tt>std::max</tt>
forces two comparisons. Worse, to compute the minimum and
maximum elements of a range of <tt>n</tt> elements requires only
<tt>3n/2+1</tt> comparisons, instead of the <tt>2n</tt> (in two passes)
forced by <tt>std::min_element</tt> and <tt>std::max_element</tt>.
I always thought it is a waste to have to call two functions to compute the
extent of a range, performing two passes over the input, when one should
be enough. The present library solves both problems.</p>
<p>The first file implements the function templates
<tt>minmax</tt>
as straightforward extensions of the C++
standard. As it returns a pair of <tt>const&amp;</tt>, we must use the <a
href=:../../../../tuple/index.html>Boost.tuple</a> library to construct such
pairs. (Please note: the intent is not to fix the known defaults of
<tt>std::min</tt>
and <tt>std::max</tt>, but to add one more algorithms that combines both; see the
<a href="#no-fix">rationale</a>.)</p>
<p>The second file implements the function templates
<tt>minmax_element</tt>. In a
second part, it also proposes variants that can usually not be computed by
the minmax algorithm, and which are more flexible in case some elements are equal.
Those variants could have been also provided with policy-based design,
but I ruled against that (see <a href="#no-policy">rationale</a>).
</p>
<p>If you are interested about
<a href="doc/minmax_benchs.html">performance</a>,
you will see that <tt>minmax_element</tt> is just slightly less efficient
than a single <tt>min_element</tt> or <tt>max_element</tt>, and thus
twice as efficient as two separate calls to <tt>min_element</tt> and
<tt>max_element</tt>. From a
theoretical standpoint,
all the <tt>minmax_element</tt> functions perform at most
<tt>3n/2+1</tt>
comparisons and exactly n increments of the
<tt>ForwardIterator</tt>.</p>

In addition, there are a bunch of extensions which specify
which element(s) you want to pick in case of equal elements. They are:
<ul>
<li><tt>first_min_element</tt> and <tt>last_min_element</tt></li>
<li><tt>first_max_element</tt> and <tt>last_max_element</tt></li>
<li><tt>first_min_first_max_element</tt>,
<tt>first_min_last_max_element</tt>,

<h3>
Function templates description</h3>
The <tt>minmax</tt> algorithm returns a pair <tt>p</tt> containing either
<i>(a,b)</i>
or <i>(b,a)</i>, such that <tt>p.first&lt;p.second</tt> in the first version,
or <tt>comp(p.first,p.second)</tt> in the second version. If the elements
are equivalent, the pair <i>(a,b) </i>is returned. <a href="#Note1">[1]</a>
<p>The <tt>minmax_element </tt>is semantically equivalent to <tt>first_min_first_max_element</tt>.
<p><tt>First_min_element</tt> and <tt>first_max_element</tt> find the smallest
and largest elements in the range <tt>[first, last)</tt>. If there are
several instance of these elements, the first one is returned. They are
identical to
<tt>std::min_element</tt> and <tt>std::max_element</tt>and
are only included in this library for symmetry.
<p><tt>Last_min_element</tt> and <tt>last_max_element</tt> find the smallest
and largest elements in the range <tt>[first, last)</tt>. They are almost
identical to
<tt>std::min_element</tt> and <tt>std::max_element</tt>, except
that they return the last instance of the largest element (and not the
first, as <tt>first_min_element</tt> and <tt>last_max_element</tt> would).
<p>The family of algorithms comprising <tt>first_min_first_max_element</tt>,
<tt>first_min_first_max_element</tt>,
<tt>first_min_first_max_element</tt>,
and <tt>first_min_first_max_element</tt> can be described generically as
follows (using <i><tt>which</tt></i> and
<i><tt>what</tt></i> for <tt>first</tt>
or <tt>last</tt>): <tt><i>which</i>_min_<i>what</i>_max_element</tt> finds
the (first or last, according to <i><tt>which</tt></i>) smallest element
and the (first or last, according to <i><tt>what</tt></i>) largest element
in the range
<tt>[first, last)</tt>. The first version is semantically
equivalent to:
<pre><tt> std::make_pair(boost::<i>which</i>_min_element(first,last),
boost::<i>what</i>_max_element(first,last))</tt>,</pre>
and the second version to:
<pre><tt> std::make_pair(boost::<i>which</i>_min_element(first,last,comp),
boost::<i>what</i>_max_element(first,last,comp))</tt>.</pre>
<p><br><b><i>Note</i></b>: the <tt>first_min_last_max_element</tt> can also be described
as finding the first and last elements in the range if it were stably sorted.

Minmax performs a single comparison and is otherwise of constant complexity.

<p>The complexity of all the other algorithms is linear. They all perform
exactly n increment operations, and zero comparisons if <tt>[first,last)</tt>
is empty, otherwise :
<ul>
<li>
all the <tt>min_element</tt> and <tt>max_element</tt> variants perform

<li>
<tt>minmax_element</tt> , <tt>first_min_first_max_element</tt>, and <tt>last_min_last_max_element</tt>
perform at most <tt>3(n/2)-1</tt> comparisons if <tt>n</tt> is even and

Notes</h3>
<a NAME="Note1"></a><a href="#Note1">[1]</a> We do not support
idioms such as <tt><a href="../../tuple/doc/tuple_users_guide.html#tiers">tie</a>(a,b)=minmax(a,b)</tt>
to order two elements <tt>a</tt>, <tt>b</tt>, although this would have
the desired effect if we returned a reference instead of a constant
reference. The reason is that two unnecessary assignments are
performed if a and b are in order. It is better to stick to <tt>if (b&lt;a)
swap(a,b)</tt> to achieve that effect.
<p><a NAME="Note2"></a><a href="#Note2">[2]</a> These algorithms always
perform at least <tt>3n/2-2</tt> comparisons, which is a lower bound on
the number of comparisons in any case (Cormen, Leiserson, Rivest: "Introduction
to Algorithms", section 9.1, Exercise 9.1-). The algorithms essentially compare
the elements in pairs, performing 1 comparison for the first two elements,
then 3 comparisons for each remaining pair of elements (one to order the
elements and one for updating each the minimum and and the maximum). When
the number of elements is odd, the last one needs to be compared to the
current minimum and also to the current maximum. In addition, for <tt>minmax</tt>,
in cases where equality of the two members in the pair could occur, and
the update stores the second, we save the first to check at the end if
the update should have stored the first (in case of equality). It's hard
to predict if the last comparison is performed or not, hence the at most
in both cases.
<p><a NAME="Note3"></a><a href="#Note3">[3]</a> These algorithms always
perform at least <tt>3n/2-2</tt> comparisons, which is a lower bound on
the number of comparisons in any case. The method is the same as in note
<a href="#Note2">[2]</a>
above, and like above, when the number of elements is odd, the last one
needs to be compared to the current minimum and also to the current maximum.
We can avoid the latter comparison if the former is successful, hence the
<i>at
most</i> instead of <i>exactly</i> in the odd case.
</a>
<a name="rationale">
<h3>
<b>Rationale:</b></h3>
<a name="two_headers">
<h4><b>Why not a single header <tt>&amp;boost/algorithm/minmax.hpp></tt>?</b></h4>
<p>This was the design originally proposed and approved in the formal
review. As the need for Boost.tuple became clear (due to the limitations
of <tt>std::pair</tt>), it became also annoying to require another
library for <tt>minmax_element</tt> which does not need it. Hence the
separation into two header files.</p>
<a name="no-fix">
<h4><b>Your minmax suffers from the same problems as std::min and
std::max.</b></h4>
<p>I am aware of the problems with std::min and
std::max, and all the debate that has been going on (please consult
<a href="http://www.cuj.com/documents/s=7996/cujcexp1904alexandr/alexandr.htm">Alexandrescu's paper</a> and the links therein). But I don't see the purpose of this
library as fixing something that is part of the C++ standard. I humbly
think it's beyond the scope of this library. Rather, I am
following the way of the standard in simply providing one more function
of the same family. If someone else wants to fix std::min, their fix
would probably apply to boost::minmax as well.</p>
</a>
<h4><b>Why no <tt>min/max_element_if</tt>?</b></h4>
<p>In a first version of the library, I proposed <tt>_if</tt> versions of
all the algorithms (well, not all, because that would be too much).
However, there is simply no reason to do so, and all the versions I had
were just as fast implemented using the excellent
<tt>&lt;boost/iterator_adaptors.hpp></tt> library. Namely, a call to
<tt>min_element_if(first, last, pred)</tt> would be just as well
implemented by:
<pre>
// equivalent to min_element_if(first, last, pred)
min_element(boost::make_filter_iterator(first, last, pred),
boost::make_filter_iterator(last, last, pred));
</pre>
Arguably, the <tt>min_element_if</tt> version is somewhat shorter, but
the overhead of iterator adaptors is not large, and they get rid of a
lot of code (think of all the combinations between first/last and
doubling them with _if variants!).</p>
<h4><b>Discussion: about std::max_element</b></h4>
<p>This rationale is somewhat historical, but explains why there are all
these <tt>first/last_min/max_element</tt> functions.</p>
<p>The C++ standard mandates that <tt>std::min_element</tt> and <tt>std::max_element</tt>
return the first instance of the smallest and largest elements (as opposed
to, say, the last). This arbitrary choice has some consistency: In the
case of v of type vector&lt;int>, for instance, it is true that <tt>std::min_element(v.begin(),v.end(),std::less&lt;int>())
== std::max_element(v.begin(),v.end(),std::greater&lt;int>())</tt>.
<p>There is of course nothing wrong with this: it's simply a matter of
choice. Yet another way to specify min_element and max_element is to define
them as the first and the last elements if the range was stably sorted.
(The <i>stable</i> sort is necessary to disambiguate between iterators
that have the same value.) In that case, min should return the first instance
and max should return the last. Then, both functions are related by
<tt>reverse_iterator(std::first_min_element(v.begin(),v.end(),std::less&lt;int>()))
==
std::last_max_element(v.rbegin(),v.rend(),std::greater&lt;int>())</tt>.
This definition is subtly different from the previous one.</p>
<p>The definition problem surfaces when one tries to design a minmax_element,
using the procedure proposed in (Cormen, Leiserson, Rivest: "Introduction
to Algorithms", section 9.1). It <i>should</i> be possible to derive an
algorithm using only <tt>3n/2</tt> comparisons if <tt>[first,last) </tt>has
<tt>n</tt>
elements, but if one tries to write a function called <tt>first_min_first_max_element()</tt>
which returns both <tt>std::min_element</tt> and <tt>std::max_element</tt>
in a pair, the trivial implementation does not work. The problem, rather
subtly, is about equal elements: I had to think for a while to find a
way to perform only three
comparisons per pair and return the first min and first max elements.
For a long time, it seemed any
attempts at doing so would consume four comparisons per pair in the worst
case. This implementation achieves three.</p>
<p>It is not possible (or even desirable) to change the meaning of
<tt>max_element</tt>,
but it is still beneficial to provide a function called <tt>minmax_element</tt>,
which returns a pair of <tt>min_element</tt> and <tt>max_element</tt>.
Although it is easy enough to call <tt>min_element</tt> and <tt>max_element</tt>,
this performs
<tt>2(n-1)</tt> comparisons, and necessitates <b>two</b>
passes over the input. In contrast,
<tt>minmax_element</tt> will perform
the fewer comparisons and perform a <b>single</b> pass over the input.
The savings can be significant when the iterator type is not a raw pointer,
or even is just a model of the InputIterator concept (although in that
case the interface would have to be
changed, as the return type could not be copied, so one could e.g.
return a value).</p>
<p>In order to benefit from all the variants of the algorithm, I propose
to introduce both <tt>first_min_element</tt> and <tt>last_min_element</tt>,
and their counterparts <tt>first_max_element</tt> and <tt>last_max_element</tt>.
Then I also propose all the variants algorithms: <tt>first_min_last_max_element</tt>
and <tt>last_min_first_max_element</tt>, which perform only at most <tt>3n/2</tt>
comparisons, and only a single pass on the input. In fact, it can be proven
that computing minmax requires at least <tt>3(n/2)-2</tt> comparisons in
any instance of the problem (Cormen, Leiserson, Rivest, 2nd edition, section
9.1). The implementation I give does not perform unnecessary comparisons
(whose result could have been computed by transitivity from previous
comparisons).</p>
<p>It appears that <tt>first_min_last_max_element</tt> may be just a tad
slower than
<tt>first_min_element</tt> alone, still much less than <tt>first_min_element</tt>
and
<tt>last_max_element</tt> called separately. <a href="#Performance">[2]</a>
<h4><b>Why algorithms and not accumulators?</b></h4>
<p>The minmax algorithms are useful in computing the extent of a range.
In computer graphics, we need a bounding box of a set of objects.
In that case the need for a single pass is even more stringent
as all three directions must be done at once. Food for thoughts: there
is matter for a nice generic programming library with stackable <tt>update_min</tt>
and <tt>update_max</tt> function objects which store a reference to the
<tt>min_result</tt>and
<tt>max_result</tt> variables, in conjunction with the <tt>for_each</tt>
algorithm).</p>
<p>I believe many standard sequential algorithms could be reformulated
with accumulators (and many others, such as in statistics, expectation /
variance / etc.). It seems that there is room for another library, but I
do not see it competing with minmax, rather extending several algorithms
(including minmax) to the accumulator framework. However, I felt it is
beyond the scope of this library to provide such accumulators.</p>
<a NAME="no-policy">
<h4><b>This first/last is a perfect application for a policy-based
design.</b></h4>
<p>True, and I could have gone that way, with the default policy for
<tt>min_element</tt> and <tt>max_element</tt> to pick the first
occurence of the result. This would have thinned the number of
combinations of the minmax_element variants. But it would also have
meant to change the interface of <tt>boost::minmax_element</tt>.
One of the goals of the <tt>minmax_element</tt> algorithm is its
eventual addition to the C++ standard, in connection with
<tt>std::min_element</tt> and <tt>std::max_element</tt>
(and I feel that it would be quite natural
given the shortness of the implementation, and the not quite trivial
detail which is needed to get it right). So changing the interface by
adding policies would have meant unfortunately to depart from the
standard and created an obstacle towards that goal. Besides, the code
remains rather readable and simple without policies. So I am quite happy
to keep it like this.

Acknowledgements</h3>
My students in CS903 (Polytechnic Univ., <a href="http://photon.poly.edu/~hbr/cs903/">http://photon.poly.edu/~hbr/cs903/</a>)
who had <tt>minmax_element</tt> as an assignment helped clarify the issues,
and also come up with the optimum number of comparisons for <tt>first_min_last_max_element</tt>.
The identification of the issue surrounding <tt>max_element</tt> is solely
my own.
<p>One <tt>minmax_element</tt> implementation, which performs <tt>3(n/2)+O(log
n)</tt> comparisons on the average when the elements are <tt>random_shuffle</tt>d,
was suggested by my student Marc Glisse. The current one, which performs
<tt>3(n/2)+1</tt>
comparisons in the worst case, was suggested by John Iacono.<p>
<p>Finally, Matthew Wilson and Jeremy Siek contributed pre-review
comments, while Gennadiy Rozental, John Maddock, Craig Henderson, Gary
Powell participated in the review of the library, managed by Thomas
Witt. In particular, Gennadiy suggested a factorization of the code;
while I haven't followed it all the way, his suggestions do make the
code more readable and still work with older compilers.
Late after the review, as I finally scrounged to add the library for a
release, Eric Niebler noted the bad behavior of <tt>std::pair</tt> for
<tt>minmax</tt> and suggested to use Boost.tuple instead.
All my thanks for the excellent advice and reviews from all.

Finder is a functor which searches for an arbitrary part of a container.

delimiting the selected part.

<para>
Various algorithms need to perform a search in a container and a Finder is a generalization of such
search operations that allows algorithms to abstract from searching. For instance, generic replace
algorithms can replace any part of the input, and the Finder is used to select the desired one.
</para>
<para>
Note, that it is only required that the finder works with a particular iterator type. However,
a Finder operation can be defined as a template, allowing the Finder to work with any iterator.

<title>Formatter concept</title>
<para>
Formatters are used by <link linkend="string_algo.replace">replace algorithms</link>.
They are used in close combination with finders.
A formatter is a functor, which takes a result from a Finder operation and transforms it in a specific way.
The operation of the formatter can use additional information provided by a specific finder,
for example <functionname>regex_formatter()</functionname> uses the match information from
<functionname>regex_finder()</functionname> to format the result of formatter operation.

<section id="string_algo.string">
<title>String Representation</title>
<para>
As the name suggest, this library works mainly with strings. However, in the context of this library,
a string is not restricted to any particular implementation (like <code>std::basic_string</code>),
rather it is a concept. This allows the algorithms in this library to be reused for any string type,
that satisfies the given requirements.
</para>
<para>
<emphasis role="bold">Definition:</emphasis> A string is a
<ulink url="../../libs/range/doc/range.html">range</ulink> of characters accessible in sequential
ordered fashion. Character is any value type with "cheap" copying and assignment.
</para>
<para>
First requirement of string-type is that it must accessible using
<ulink url="../../libs/range/index.html">Boost.Range</ulink>. This facility allows to access
the elements inside the string in a uniform iterator-based fashion.
This is sufficient for our library
</para>
<para>
Second requirement defines the way in which the characters are stored in the string. Algorithms in
this library work with an assumption that copying a character is cheaper then allocating extra
storage to cache results. This is a natural assumption for common character types. Algorithms will
work even if this requirement is not satisfied, however at the cost of performance degradation.
<para>
</para>
In addition some algorithms have additional requirements on the string-type. Particularly, it is required
that an algorithm can create a new string of the given type. In this case, it is required that
the type satisfies the sequence (Std &sect;23.1.1) requirements.
</para>
<para>
In the reference and also in the code, requirement on the string type is designated by the name of
template argument. <code>RangeT</code> means that the basic range requirements must hold.
<code>SequenceT</code> designates extended sequence requirements.
</para>
</section>
<section id="string_algo.sequence_traits">
<title>Sequence Traits</title>
<para>
The major difference between <code>std::list</code> and <code>std::vector</code> is not in the interfaces
they provide, but rather in the inner details of the class and the way how it performs
various operations. The problem is that it is not possible to infer this difference from the
definitions of classes without some special mechanism.
However, some algorithms can run significantly faster with the knowledge of the properties
of a particular container.
</para>
<para>
Sequence traits allow one to specify additional properties of a sequence container (see Std.&sect;32.2).
These properties are then used by algorithms to select optimized handling for some operations.
The sequence traits are declared in the header
<headername>boost/algorithm/string/sequence_traits.hpp</headername>.
</para>
<para>
In the table C denotes a container and c is an object of C.

<para>
Current implementation contains specializations for std::list&lt;T&gt; and
std::basic_string&lt;T&gt; from the standard library and SGI's std::rope&lt;T&gt; and std::slist&lt;T&gt;.
</para>
</section>
<section id="string_algo.find">
<title>Find Algorithms</title>
<para>
Find algorithms have similar functionality to <code>std::search()</code> algorithm. They provide a different
interface which is more suitable for common string operations.
Instead of returning just the start of matching subsequence they return a range which is necessary
when the length of the matching subsequence is not known beforehand.
This feature also allows a partitioning of the input sequence into three
parts: a prefix, a substring and a suffix.
</para>
<para>
Another difference is an addition of various searching methods besides find_first, including find_regex.
</para>
<para>
It the library, find algorithms are implemented in terms of
<link linkend="string_algo.finder_concept">Finders</link>. Finders are used also by other facilities
(replace,split).
For convenience, there are also function wrappers for these finders to simplify find operations.
</para>
<para>
Currently the library contains only naive implementation of find algorithms with complexity
O(n * m) where n is the size of the input sequence and m is the size of the search sequence.
There are algorithms with complexity O(n), but for smaller sequence a constant overhead is
rather big. For small m &lt;&lt; n (m by magnitude smaller than n) the current implementation
provides acceptable efficiency.
Even the C++ standard defines the required complexity for search algorithm as O(n * m).
It is possible that a future version of library will also contain algorithms with linear
complexity as an option
</para>
</section>
<section id="string_algo.replace">
<title>Replace Algorithms</title>
<para>
The implementation of replace algorithms follows the layered structure of the library. The
lower layer implements generic substitution of a range in the input sequence.
This layer takes a <link linkend="string_algo.finder_concept">Finder</link> object and a
<link linkend="string_algo.formatter_concept">Formatter</link> object as an input. These two
functors define what to replace and what to replace it with. The upper layer functions
are just wrapping calls to the lower layer. Finders are shared with the find and split facility.
</para>
<para>
As usual, the implementation of the lower layer is designed to work with a generic sequence while
taking advantage of specific features if possible
(by using <link linkend="string_algo.sequence_traits">Sequence traits</link>)
</para>
</section>
<section id="string_algo.split">
<title>Find Iterators &amp; Split Algorithms</title>
<para>
Find iterators are a logical extension of the <link linkend="string_algo.find">find facility</link>.
Instead of searching for one match, the whole input can be iteratively searched for multiple matches.
The result of the search is then used to partition the input. It depends on the algorithms which parts
are returned as the result. They can be the matching parts (<classname>find_iterator</classname>) of the parts in
between (<classname>split_iterator</classname>).
</para>
<para>
In addition the split algorithms like <functionname>find_all()</functionname> and <functionname>split()</functionname>
can simplify the common operations. They use a find iterator to search the whole input and copy the
matches they found into the supplied container.
</para>
</section>
<section id="string_algo.exception">
<title>Exception Safety</title>
<para>
The library requires that all operations on types used as template
or function arguments provide the <emphasis>basic exception-safety guarantee</emphasis>.
In turn, all functions and algorithms in this library, except where stated
otherwise, will provide the <emphasis>basic exception-safety guarantee</emphasis>.
In other words:
The library maintains its invariants and does not leak resources in
the face of exceptions. Some library operations give stronger
guarantees, which are documented on an individual basis.
</para>
<para>
Some functions can provide the <emphasis>strong exception-safety guarantee</emphasis>.
That means that following statements are true:
<itemizedlist>
<listitem>
If an exception is thrown, there are no effects other than those
of the function
</listitem>
<listitem>
If an exception is thrown other than by the function, there are no effects
</listitem>
</itemizedlist>
This guarantee can be provided under the condition that the operations
on the types used for arguments for these functions either
provide the strong exception guarantee or do not alter the global state .
</para>
<para>
In the reference, under the term <emphasis>strong exception-safety guarantee</emphasis>, we mean the
guarantee as defined above.
</para>
<para>

There are known limitation on platforms not supporting partial template specialization.
Library depends on correctly implemented <code>std::iterator_traits</code> class.
If a standard library provided with compiler is broken, the String Algorithm Library
cannot function properly. Usually it implies that primitive pointer iterators are not
working with the library functions.

the template parameter(s) must satisfy certain requirements.Often these
requirements are so important that we give them a name: we call
such a set of type requirements a <b>concept</b>. We say that a type <i>
conforms to a concept</i> or that it <i>is a model of a concept</i> if it
satisfies all of those requirements. The concept can be specified as a set
of member functions with well-defined semantics
and a set of nested typedefs with well-defined properties.</p><p >Often it much more flexible to provide free-standing functions and typedefs
which provides the exact same semantics (but a different syntax) as
specified
by the concept. This allows generic code to treat different types <i> as if
</i> they fulfilled the concept. In this case we say that the concept has
been <b> externalized </b> or that the new requirements constitutes an <b>external
concept </b>. We say that a type <i> conforms to an external concept </i>
or that it <i> is a model of an external concept </i>. A concept may exist
without a corresponding external concept and conversely.</p><p >Whenever a concept specifies a member function, the corresponding external
concept
must specify a free-standing function of the same name, same return type and
the same argument list except there is an extra first argument which must
be of the type (or a reference to that type) that is to fulfill the external
concept. If the corresonding member function has any cv-qulifiers, the
first argument must have the same cv-qualifiers. Whenever a concept
specifies a nested typedef, the corresponding external concept
specifies a <b>type-generator</b>, that is, a type with a nested typedef
named <code>type</code>. The type-generator has the name as the nested typedef with
<code>_of</code> appended.
The converse relationship of an external concept and its corresponding concept
also holds.</p><p ><b ><i >Example:</i></b></p><p >A type <code>T</code> fulfills the FooConcept if it
has the follwing public members:</p><code> void T::foo( int ) const; <br>
int T::bar(); <br>
typedef <i>implementation defined </i> foo_type;</code><p >The corresponding external concept is the ExternalFooConcept.</p><p >A type <code>T</code> fullfills the ExternalFooConcept if these
free-standing functions and type-generators exists:</p><code>void foo( const T&, int ); <br>
int bar( T& ); <br>

<title>Introduction</title>
<para>
The String Algorithm Library provides a generic implementation of
string-related algorithms which are missing in STL. It is an extension
to the algorithms library of STL and it includes trimming, case conversion,
predicates and find/replace functions. All of them come in different variants
so it is easier to choose the best fit for a particular need.
</para>
<para>
The implementation is not restricted to work with a particular container
(like <code>std::basic_string</code>), rather it is as generic as
possible. This generalization is not compromising the performance since
algorithms are using container specific features when it means a performance
gain.
</para>
<para>
<emphasis role="bold">
Important note: In this documentation we use term <emphasis>string</emphasis> to
designate a sequence of <emphasis>characters</emphasis> stored in an arbitrary container.
A <emphasis>string</emphasis> is not restricted to <code>std::basic_string</code> and
<emphasis>character</emphasis> does not have to be <code>char</code> or <code>wchar_t</code>,
although these are most common candidates.
</emphasis>
Consult the <link linkend="string_algo.design">design chapter</link> to see precise specification of
supported string types.
</para>
<para>
The library interface functions and classes are defined in namespace <code>boost::algorithm</code>, and
they are lifted into namespace <code>boost</code> via using declaration.
</para>
<para>
The documentation is divided into several sections. For a quick start read the
<link linkend="string_algo.usage">Usage</link> section followed by
<link linkend="string_algo.quickref">Quick Reference</link>.
<link linkend="string_algo.design">The Design Topics</link>,
<link linkend="string_algo.concept">Concepts</link> and <link linkend="string_algo.rationale">Rationale</link>
provide some explanation about the library design and structure an explain how it should be used.
See the <link linkend="string_algo.reference">Reference</link> for the complete list of provided utilities
and algorithms. Functions and classes in the reference are organized by the headers in which they are defined.
The reference contains links to the detailed description for every entity in the library.

<title>Rationale</title>
<using-namespace name="boost"/>
<using-namespace name="boost::algorithm"/>
<section it="string_algo.locale">
<title>Locales</title>
<para>
Locales have a very close relation to string processing. They contain information about
the character sets and are used, for example, to change the case of characters and
to classify the characters.
</para>
<para>
C++ allows to work with multiple different instances of locales at once. If an algorithm
manipulates some data in a way that requires the usage of locales, there must be a way
to specify them. However, one instance of locales is sufficient for most of the applications,
and for a user it could be very tedious to specify which locales to use at every place
where it is needed.
</para>
<para>
Fortunately, the C++ standard allows to specify the <emphasis>global</emphasis> locales (using static member
function <code>std:locale::global()</code>). When instantiating an
<code>std::locale</code> class without explicit information, the instance will
be initialized with the <emphasis>global</emphasis> locale. This implies, that if an algorithm needs a locale,
it should have an <code>std::locale</code> parameter defaulting to <code>std::locale()</code>.
If a user needs to specify locales explicitly, she can do so. Otherwise the <emphasis>global</emphasis>
locales are used.
</para>
</section>
<section id="string_algo.regex">
<title>Regular Expressions</title>
<para>
Regular expressions are an essential part of text processing. For this reason, the library
also provides regex variants of some algorithms. The library does not attempt to replace
<libraryname>Boost.Regex</libraryname>; it merely wraps its functionality in a new interface.
As a part of this library, regex algorithms integrate smoothly with other components, which
brings additional value.

<section id="string_algo.usage" last-revision="$Date$">
<title>Usage</title>
<using-namespace name="boost"/>
<using-namespace name="boost::algorithm"/>
<section>
<title>First Example</title>
<para>
Using the algorithms is straightforward. Let us have a look at the first example:
</para>
<programlisting>
#include &lt;boost/algorithm/string.hpp&gt;
using namespace std;
using namespace boost;
// ...
string str1(" hello world! ");
to_upper(str1); // str1 == " HELLO WORLD! "
trim(str1); // str1 == "HELLO WORLD!"
string str2=
to_lower_copy(
ireplace_first_copy(
str1,"hello","goodbye")); // str2 == "goodbye world!"
</programlisting>
<para>
This example converts str1 to upper case and trims spaces from the start and the end
of the string. str2 is then created as a copy of str1 with "hello" replaced with "goodbye".
This example demonstrates several important concepts used in the library:
</para>
<itemizedlist>
<listitem>
<para><emphasis role="bold">Container parameters:</emphasis>
Unlike in the STL algorithms, parameters are not specified only in the form
of iterators. The STL convention allows for great flexibility,
but it has several limitations. It is not possible to <emphasis>stack</emphasis> algorithms together,
because a container is passed in two parameters. Therefore it is not possible to use
a return value from another algorithm. It is considerably easier to write
<code>to_lower(str1)</code>, than <code>to_lower(str1.begin(), str1.end())</code>.
</para>
<para>
The magic of <ulink url="../../libs/range/index.html">Boost.Range</ulink>
provides a uniform way of handling different string types.
If there is a need to pass a pair of iterators,
<ulink url="../../libs/range/doc/utility_class.html"><code>boost::iterator_range</code></ulink>
can be used to package iterators into a structure with a compatible interface.
</para>
</listitem>
<listitem>
<para><emphasis role="bold">Copy vs. Mutable:</emphasis>
Many algorithms in the library are performing a transformation of the input.
The transformation can be done in-place, mutating the input sequence, or a copy
of the transformed input can be created, leaving the input intact. None of
these possibilities is superior to the other one and both have different
advantages and disadvantages. For this reason, both are provided with the library.
</para>
</listitem>
<listitem>
<para><emphasis role="bold">Algorithm stacking:</emphasis>
Copy versions return a transformed input as a result, thus allow a simple chaining of
transformations within one expression (i.e. one can write <code>trim_copy(to_upper_copy(s))</code>).
Mutable versions have <code>void</code> return, to avoid misuse.
</para>
</listitem>
<listitem>
<para><emphasis role="bold">Naming:</emphasis>
Naming follows the conventions from the Standard C++ Library. If there is a
copy and a mutable version of the same algorithm, the mutable version has no suffix
and the copy version has the suffix <emphasis>_copy</emphasis>.
Some algorithms have the prefix <emphasis>i</emphasis>
(e.g. <functionname>ifind_first()</functionname>).
This prefix identifies that the algorithm works in a case-insensitive manner.
</para>
</listitem>
</itemizedlist>
<para>
To use the library, include the <headername>boost/algorithm/string.hpp</headername> header.
If the regex related functions are needed, include the
<headername>boost/algorithm/string_regex.hpp</headername> header.
</para>
</section>
<section>
<title>Case conversion</title>
<para>
STL has a nice way of converting character case. Unfortunately, it works only
for a single character and we want to convert a string,
</para>
<programlisting>
string str1("HeLlO WoRld!");
to_upper(str1); // str1=="HELLO WORLD!"
</programlisting>
<para>
<functionname>to_upper()</functionname> and <functionname>to_lower()</functionname> convert the case of
characters in a string using a specified locale.
</para>
<para>
For more information see the reference for <headername>boost/algorithm/string/case_conv.hpp</headername>.
</para>
</section>
<section>
<title>Predicates and Classification</title>
<para>
A part of the library deals with string related predicates. Consider this example:
</para>
<programlisting>
bool is_executable( string&amp; filename )
{
return
iends_with(filename, ".exe") ||
iends_with(filename, ".com");
}
// ...
string str1("command.com");
cout
&lt;&lt; str1
&lt;&lt; is_executable("command.com")? "is": "is not"
&lt;&lt; "an executable"
&lt;&lt; endl; // prints "command.com is an executable"
//..
char text1[]="hello world!";
cout
&lt;&lt; text1
&lt;&lt; all( text1, is_lower() )? "is": "is not"
&lt;&lt; " written in the lower case"
&lt;&lt; endl; // prints "hello world! is written in the lower case"
</programlisting>
<para>
The predicates determine whether if a substring is contained in the input string
under various conditions. The conditions are: a string starts with the substring,
ends with the substring,
simply contains the substring or if both strings are equal. See the reference for
<headername>boost/algorithm/string/predicate.hpp</headername> for more details.
</para>
<para>
In addition the algorithm <functionname>all()</functionname> checks
all elements of a container to satisfy a condition specified by a predicate.
This predicate can be any unary predicate, but the library provides a bunch of
useful string-related predicates and combinators ready for use.
These are located in the <headername>boost/algorithm/string/classification.hpp</headername> header.
Classification predicates can be combined using logical combinators to form
a more complex expressions. For example: <code>is_from_range('a','z') || is_digit()</code>
</para>
</section>
<section>
<title>Trimming</title>
<para>
When parsing the input from a user, strings usually have unwanted leading or trailing
characters. To get rid of them, we need trim functions:
</para>
<programlisting>
string str1=" hello world! ";
string str2=trim_left_copy(str1); // str2 == "hello world! "
string str3=trim_right_copy(str2); // str3 == " hello world!"
trim(str1); // str1 == "hello world!"
string phone="00423333444";
// remove leading 0 from the phone number
trim_left_if(phone,is_any_of("0")); // phone == "423333444"
</programlisting>
<para>
It is possible to trim the spaces on the right, on the left or on both sides of a string.
And for those cases when there is a need to remove something else than blank space, there
are <emphasis>_if</emphasis> variants. Using these, a user can specify a functor which will
select the <emphasis>space</emphasis> to be removed. It is possible to use classification
predicates like <functionname>is_digit()</functionname> mentioned in the previous paragraph.
See the reference for the <headername>boost/algorithm/string/trim.hpp</headername>.
</para>
</section>
<section>
<title>Find algorithms</title>
<para>
The library contains a set of find algorithms. Here is an example:
</para>
<programlisting>
char text[]="hello dolly!";
iterator_range&lt;char*&gt; result=find_last(text,"ll");
transform( result.begin(), result.end(), result.begin(), bind2nd(plus&lt;char&gt;(), 1) );
// text = "hello dommy!"
to_upper(result); // text == "hello doMMy!"
// iterator_range is convertible to bool
if(find_first(text, "dolly"))
{
cout &lt;&lt; "Dolly is there" &lt;&lt; endl;
}
</programlisting>
<para>
We have used <functionname>find_last()</functionname> to search the <code>text</code> for "ll".
The result is given in the <ulink url="../../libs/range/doc/utility_class.html"><code>boost::iterator_range</code></ulink>.
This range delimits the
part of the input which satisfies the find criteria. In our example it is the last occurrence of "ll".
As we can see, input of the <functionname>find_last()</functionname> algorithm can be also
char[] because this type is supported by
<ulink url="../../libs/range/index.html">Boost.Range</ulink>.
The following lines transform the result. Notice that
<ulink url="../../libs/range/doc/utility_class.html"><code>boost::iterator_range</code></ulink> has familiar
<code>begin()</code> and <code>end()</code> methods, so it can be used like any other STL container.
Also it is convertible to bool therefore it is easy to use find algorithms for a simple containment checking.
</para>
<para>
Find algorithms are located in <headername>boost/algorithm/string/find.hpp</headername>.
</para>
</section>
<section>
<title>Replace Algorithms</title>
<para>
Find algorithms can be used for searching for a specific part of string. Replace goes one step
further. After a matching part is found, it is substituted with something else. The substitution is computed
from the original, using some transformation.
</para>
<programlisting>
string str1="Hello Dolly, Hello World!"
replace_first(str1, "Dolly", "Jane"); // str1 == "Hello Jane, Hello World!"
replace_last(str1, "Hello", "Goodbye"); // str1 == "Hello Jane, Goodbye World!"
erase_all(str1, " "); // str1 == "HelloJane,GoodbyeWorld!"
erase_head(str1, 6); // str1 == "Jane,GoodbyeWorld!"
</programlisting>
<para>
For the complete list of replace and erase functions see the
<link linkend="string_algo.reference">reference</link>.
There is a lot of predefined function for common usage, however, the library allows you to
define a custom <code>replace()</code> that suits a specific need. There is a generic <functionname>find_format()</functionname>
function which takes two parameters.
The first one is a <link linkend="string_algo.finder_concept">Finder</link> object, the second one is
a <link linkend="string_algo.formatter_concept">Formatter</link> object.
The Finder object is a functor which performs the searching for the replacement part. The Formatter object
takes the result of the Finder (usually a reference to the found substring) and creates a
substitute for it. Replace algorithm puts these two together and makes the desired substitution.
</para>
<para>
Check <headername>boost/algorithm/string/replace.hpp</headername>, <headername>boost/algorithm/string/erase.hpp</headername> and
<headername>boost/algorithm/string/find_format.hpp</headername> for reference.
</para>
</section>
<section>
<title>Find Iterator</title>
<para>
An extension to find algorithms it the Find Iterator. Instead of searching for just a one part of a string,
the find iterator allows us to iterate over the substrings matching the specified criteria.
This facility is using the <link linkend="string_algo.finder_concept">Finder</link> to incrementally
search the string.
Dereferencing a find iterator yields an <ulink url="../../libs/range/doc/utility_class.html"><code>boost::iterator_range</code></ulink>
object, that delimits the current match.
</para>
<para>
There are two iterators provided <classname>find_iterator</classname> and
<classname>split_iterator</classname>. The former iterates over substrings that are found using the specified
Finder. The latter iterates over the gaps between these substrings.
</para>
<programlisting>
string str1("abc-*-ABC-*-aBc");
// Find all 'abc' substrings (ignoring the case)
// Create a find_iterator
typedef find_iterator&lt;string::iterator&gt; string_find_iterator;
for(string_find_iterator It=
make_find_iterator(str1, first_finder("abc", is_iequal()));
It!=string_find_iterator();
++It)
{
cout &lt;&lt; copy_range&lt;std::string&gt;(*It) &lt;&lt; endl;
}
// Output will be:
// abc
// ABC
// aBC
typedef split_iterator&lt;string::iterator&gt; string_split_iterator;
for(string_split_iterator It=
make_split_iterator(str1, first_finder("-*-", is_iequal()));
It!=string_split_iterator();
++It)
{
cout &lt;&lt; copy_range&lt;std::string&gt;(*It) &lt;&lt; endl;
}
// Output will be:
// abc
// ABC
// aBC
</programlisting>
<para>
Note that the find iterators have only one template parameter. It is the base iterator type.
The Finder is specified at runtime. This allows us to typedef a find iterator for
common string types and reuse it. Additionally make_*_iterator functions help
to construct a find iterator for a particular range.
</para>
<para>
See the reference in <headername>boost/algorithm/string/find_iterator.hpp</headername>.
</para>
</section>
<section>
<title>Split</title>
<para>
Split algorithms are an extension to the find iterator for one common usage scenario.
These algorithms use a find iterator and store all matches into the provided
container. This container must be able to hold copies (e.g. <code>std::string</code>) or
references (e.g. <code>iterator_range</code>) of the extracted substrings.
</para>
<para>
Two algorithms are provided. <functionname>find_all()</functionname> finds all copies
of a string in the input. <functionname>split()</functionname> splits the input into parts.
</para>
<programlisting>
string str1("hello abc-*-ABC-*-aBc goodbye");
typedef vector&lt; iterator_range&lt;string::iterator&gt; &gt; find_vector_type;
find_vector_type FindVec; // #1: Search for separators
ifind_all( FindVec, str1, "abc" ); // FindVec == { [abc],[ABC],[aBc] }
typedef vector&lt; string &gt; split_vector_type;
split_vector_type SplitVec; // #2: Search for tokens
split( SplitVec, str1, is_any_of("-*") ); // SplitVec == { "hello abc","ABC","aBc goodbye" }
</programlisting>
<para>
<code>[hello]</code> designates an <code>iterator_range</code> delimiting this substring.
</para>
<para>
First example show how to construct a container to hold references to all extracted
substrings. Algorithm <functionname>ifind_all()</functionname> puts into FindVec references
to all substrings that are in case-insensitive manner equal to "abc".
</para>
<para>
Second example uses <functionname>split()</functionname> to split string str1 into parts
separated by characters '-' or '*'. These parts are then put into the SplitVec.
It is possible to specify if adjacent separators are concatenated or not.
</para>
<para>
More information can be found in the reference: <headername>boost/algorithm/string/split.hpp</headername>.
</para>
