<p>
The high level wrapper class RegEx is now deprecated and does not form
part of the regular expression standardization proposal. This type still
exists, and existing code will continue to compile, however the following
documentation is unlikely to be further updated.
</p>
<pre class="programlisting"><span class="preprocessor">#include</span> <span class="special"><</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">cregex</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">></span>
</pre>
<p>
The class RegEx provides a high level simplified interface to the regular
expression library, this class only handles narrow character strings, and
regular expressions always follow the "normal" syntax - that
is the same as the perl / ECMAScript syntax.

For each match found calls the call-back function cb as: <code class="computeroutput"><span class="identifier">cb</span><span class="special">(*</span><span class="keyword">this</span><span class="special">);</span></code>
If at any stage the call-back function returns false then the
grep operation terminates, otherwise continues until no further
matches are found. Returns the number of matches found.
