template<typename _CharT>
class std::__detail::_Scanner< _CharT >

Scans an input range for regex tokens.

The _Scanner class interprets the regular expression pattern in the input range passed to its constructor as a sequence of parse tokens passed to the regular expression compiler. The sequence of tokens provided depends on the flag settings passed to the constructor: different regular expression grammars will interpret the same input pattern in syntactically different ways.
