Non-member Functions

swap(std::basic_regex)

 

Defined in header <regex>
template <     class CharT = char,     class Traits = std::regex_traits<CharT> > class basic_regex;		(since C++11)

The class template basic_regex provides a general framework for holding regular expressions.

Several specializations for common character types are provided:

Defined in header <regex>
Type	Definition
regex	basic_regex<char>
wregex	basic_regex<wchar_t>

Member types

Member type	Definition
value_type	CharT
traits_type	Traits
string_type	Traits::string_type
locale_type	Traits::locale_type
flag_type	std::regex_constants::syntax_option_type

Member functions

(constructor)	constructs the regex object (public member function)

Modifiers
swap	swaps the contents (public member function)
Constants
Value	Effect(s)
icase	ignore case
