- <p id="label-algorithms-transformation-algorithms">According to their name, MPL's <em>transformation</em>, or <em>sequence-building
- algorithms</em> provide the tools for building new sequences from the existing
- ones by performing some kind of transformation. A typical transformation
- alogrithm takes one or more input sequences and a transformation
- metafunction/predicate, and returns a new sequence built according to the
- algorithm's semantics through the means of its <a class="reference internal" href="./inserter.html">Inserter</a> argument, which
- plays a role similar to the role of run-time <a class="reference external" href="https://boost.org/sgi/stl/OutputIterator.html" target="_top">Output Iterator</a>.</p>
- <!-- Say something about optionality of Inserters/their default behavior -->
- <p>Every transformation algorithm is a <a class="reference internal" href="./reversible-algorithm.html">Reversible Algorithm</a>, providing
- an accordingly named <tt class="literal"><span class="pre">reverse_</span></tt> counterpart carrying the transformation
- in the reverse order. Thus, all sequence-building algorithms come in pairs,
- for instance <tt class="literal"><span class="pre"><a href="./replace.html" class="identifier">replace</a></span></tt> / <tt class="literal"><span class="pre"><a href="./reverse-replace.html" class="identifier">reverse_replace</a></span></tt>. In presence of variability of
- the output sequence's properties such as front or backward extensibility,
- the existence of the bidirectional algorithms allows for the most efficient
- way to perform the required transformation.</p>
