Detailed Description

template<typename _Ch_type, typename _Rx_traits = regex_traits<_Ch_type>>
class std::basic_regex< _Ch_type, _Rx_traits >

Objects of specializations of this class represent regular expressions constructed from sequences of character type _Ch_type.

Storage for the regular expression is allocated and deallocated as necessary by the member functions of this class.
