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)
(destructor)	destructs the regex object (public member function)
operator=	assigns the contents (public member function)
assign	assigns the contents (public member function)
Observers
mark_count	returns the number of marked sub-expressions within the regular expression (public member function)
flags	returns the syntax flags (public member function)
Locale
getloc	get locale information (public member function)
imbue	set locale information (public member function)
Modifiers
swap	swaps the contents (public member function)
Constants
Value	Effect(s)
icase	ignores case when matching characters
nosubs	does not store sub-expression matches
optimize	faster matching, slower construction
collate	makes range expressions locale-sensitive
ECMAScript	uses an ECMA-262 (Perl 5) syntax
basic	uses a POSIX basic regular expression syntax
extended	uses a POSIX extended regular expression syntax
awk	uses an awk-compatible syntax
grep	uses a grep-compatible syntax
egrep	uses an extended grep-compatible syntax

Non-member functions

std::swap(std::basic_regex) (C++11)	specializes the std::swap algorithm (function template)
