The template class <code class="computeroutput"><span class="identifier">basic_regex</span></code>
|
||
encapsulates regular expression parsing and compilation. The class takes
|
||
two template parameters:
|
||
</p>
|
||
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
|
||
<li class="listitem">
|
||
<code class="computeroutput"><span class="identifier">charT</span></code>: determines the
|
||
character type, i.e. either <code class="computeroutput"><span class="keyword">char</span></code>
|
||
or <code class="computeroutput"><span class="keyword">wchar_t</span></code>; see <a class="link" href="concepts/charT_concept.html" title="charT Requirements">charT
|
||
concept</a>.
|
||
</li>
|
||
<li class="listitem">
|
||
<code class="computeroutput"><span class="identifier">traits</span></code>: determines the
|
||
behavior of the character type, for example which character class names
|
||
are recognized. A default traits class is provided: <code class="computeroutput"><span class="identifier">regex_traits</span><span class="special"><</span><span class="identifier">charT</span><span class="special">></span></code>. See also <a class="link" href="concepts/traits_concept.html" title="Traits Class Requirements">traits
|
||
concept</a>.
|
||
</li>
|
||
</ul></div>
|
||
<p>
|
||
For ease of use there are two typedefs that define the two standard <code class="computeroutput"><span class="identifier">basic_regex</span></code> instances, unless you want
|
||
to use custom traits classes or non-standard character types (for example
|
||
see <a class="link" href="non_std_strings/icu.html" title="Working With Unicode and ICU String Types">unicode support</a>),
|
||
you won't need to use anything other than these:

The definition of <code class="computeroutput"><span class="identifier">basic_regex</span></code>
|

follows: it is based very closely on class <code class="computeroutput"><span class="identifier">basic_string</span></code>,
|

and fulfils the requirements for a constant-container of <code class="computeroutput"><span class="identifier">charT</span></code>.
