Detailed Description
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.
