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.

Member Function Documentation
template<typename _Ch_type, typename _Rx_traits = regex_traits<_Ch_type>>
basic_regex& std::basic_regex< _Ch_type, _Rx_traits >::assign
(initializer_list< _Ch_type > __l, flag_type __f =
regex_constants::ECMAScript) [inline]
Assigns a new regular expression to a regex object. Parameters:
l An initializer list representing a regular expression.
flags Syntax option flags.
Exceptions:
regex_error if l does not contain a valid regular expression
pattern interpreted according to flags. If regex_error is thrown,
the object remains unchanged.
