C++ API: Regular Expressions.

<h2>Regular Expression API</h2>
<p>
The ICU API for processing regular expressions consists of two classes, <code><a class="el" href="classRegexPattern.html">RegexPattern</a></code> and <code><a class="el" href="classRegexMatcher.html">RegexMatcher</a></code>. <code><a class="el" href="classRegexPattern.html">RegexPattern</a></code> objects represent a pre-processed, or compiled regular expression. They are created from a regular expression pattern string, and can be used to create <code><a class="el" href="classRegexMatcher.html">RegexMatcher</a></code> objects for the pattern.<p>
Class <code><a class="el" href="classRegexMatcher.html">RegexMatcher</a></code> bundles together a regular expression pattern and a target string to which the search pattern will be applied. <code><a class="el" href="classRegexMatcher.html">RegexMatcher</a></code> includes API for doing plain find or search operations, for search and replace operations, and for obtaining detailed information about bounds of a match. <p>
Note that by constructing <code><a class="el" href="classRegexMatcher.html">RegexMatcher</a></code> objects directly from regular expression pattern strings application code can be simplified and the explicit need for <code><a class="el" href="classRegexPattern.html">RegexPattern</a></code> objects can usually be eliminated.
