<p>The template class <em>basic_regex</em> encapsulates regular expression parsing
|
|
|
|
|
|
and compilation. The class takes three template parameters:</p>
|
|
|
|
|
|
<p><b><i>charT</i></b>: determines the character type, i.e. either char or
|
|
|
|
|
|
wchar_t.</p>
|
|
|
|
|
|
<p><b><i>traits</i></b>: determines the behavior of the character type, for
|
|
|
|
|
|
example which character class names are recognized. A default traits class is
|
|
|
|
|
|
provided: <a href="regex_traits.html">regex_traits<charT></a>.</p>
|
|
|
|
|
|
<p><b><i>Allocator</i></b>: the allocator class used to allocate memory by the
|
|
|
|
|
|
class.</p>
|
|
|
|
|
|
<p>For ease of use there are two typedefs that define the two standard <i>basic_regex</i>
|
|
|
|
|
|
instances, unless you want to use custom traits classes or allocators, you
|
|
|
|
|
|
won't need to use anything other than these:</p>

<p>The definition of <i>basic_regex</i> follows: it is based very closely on class
|
|
|
|
|
|
basic_string, and fulfils the requirements for a constant-container of <i>charT</i>.</p>
