Detailed Description
template<typename _InputIterator>class std::__detail::_Scanner<
_InputIterator >
struct _Scanner. 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.
