|
|
<a class="target" id="label-algorithms" name="label-algorithms"></a><p>The MPL provides a broad range of fundamental algorithms aimed to
|
|
satisfy the majority of sequential compile-time data processing
|
|
needs. The algorithms include compile-time counterparts
|
|
of many of the STL algorithms, iteration algorithms borrowed from
|
|
functional programming languages, and more.</p>
|
|
<p>Unlike the algorithms in the C++ Standard Library, which operate on
|
|
implict <em>iterator ranges</em>, the majority of MPL counterparts take
|
|
and return <em>sequences</em>. This derivation is not dictated by the
|
|
functional nature of C++ compile-time computations per se, but
|
|
rather by a desire to improve general usability of the library,
|
|
making programming with compile-time data structures as enjoyable
|
|
as possible.</p>
|
|
<!-- This can be seen as a further generalization and extension of
|
|
the STL's conceptual framework. -->
|
|
<p>In the spirit of the STL, MPL algorithms are <em>generic</em>, meaning
|
|
that they are not tied to particular sequence class
|
|
implementations, and can operate on a wide range of arguments as
|
|
long as they satisfy the documented requirements. The requirements
|
|
are formulated in terms of concepts. Under the hood,
|
|
algorithms are decoupled from concrete sequence
|
|
implementations by operating on <a class="reference" href="./iterators.html">Iterators</a>.</p>
|
|
<p>All MPL algorithms can be sorted into three
|
|
major categories: iteration algorithms, querying algorithms, and
|
|
transformation algorithms. The transformation algorithms introduce
|
|
an associated <a class="reference" href="./inserter.html">Inserter</a> concept, a rough equivalent for the notion of
|
|
<a class="reference" href="http://www.sgi.com/tech/stl/OutputIterator.html" target="_top">Output Iterator</a> in the Standard Library. Moreover, every
|
|
transformation algorithm provides a <tt class="literal"><span class="pre">reverse_</span></tt> counterpart,
|
|
allowing for a wider range of efficient transformations — a
|
|
common functionality documented by the <a class="reference" href="./reversible-algorithm.html">Reversible Algorithm</a>
|
|
concept.</p>
