std::basic_string
 
basic_string& operator=( const basic_string& str );
(1)
basic_string& operator=( basic_string&& str );
(2) (since C++11)
basic_string& operator=( const CharT* s );
(3)
basic_string& operator=( CharT ch );
(4)
basic_string& operator=( std::initializer_list<CharT> ilist );
(5) (since C++11)

Replaces the contents of the string.

1) Replaces the contents with a copy of str

2) Replaces the contents with those of str using move semantics. str is in undefined state after the operation.

3) Replaces the contents with those of null-terminated character string pointed to by s.

4) Replaces the contents with character ch

8) Replaces the contents with those of the initializer list ilist.

Contents

[edit] Parameters

ch - value to initialize characters of the string with
str - string to be used as source to initialize the string with
s - pointer to a null-termanated character string
to use as source to initialize the string with
init - initializer list to initialize the string with

[edit] Return value

*this

[edit] Complexity

1) linear in size of str

2) constant. If alloc is given and alloc != other.get_allocator(), then linear.

3) linear in size of s

4) constant.

5) linear in size of init
