Defined in header <regex>
basic_regex& operator=( const basic_regex& other );	(1)	(since C++11)
basic_regex& operator=( basic_regex&& other ) noexcept;	(2)	(since C++11)
basic_regex& operator=( const CharT* ptr );	(3)	(since C++11)
basic_regex& operator=( std::initializer_list<CharT> il );	(4)	(since C++11)
template< class ST, class SA > basic_regex& operator=( const std::basic_string<CharT,ST,SA>& p );	(5)	(since C++11)

Assigns the contents.

1) Copy assignment operator. Assigns the contents of other. Equivalent to assign(other);.

2) Move assignment operator. Assigns the contents of other using move semantics. other is in valid, but unspecified state after the operation. Equivalent to assign(other);.

3) Assigns a null-terminated character string pointed to by ptr. Equivalent to assign(ptr);.

4) Assigns characters contained in initializer list il. Equivalent to assign(il);.

5) Assigns the contents of the string p. Equivalent to assign(p);.

Parameters

other	-	another regex object
ptr	-	pointer to a null-terminated character string
il	-	initializer list containing characters to assign
p	-	string containing characters to assign

Return value

*this

Exceptions

1) May throw implementation-defined exceptions.

3-5) std::regex_error if the supplied regular expression is not valid. The object is not modified in that case.
