queue& operator=( const queue& other );	(1)	(implicitly declared)
queue& operator=( queue&& other );	(2)	(since C++11) (implicitly declared)

Replaces the contents of the container adaptor with the contents of given argument.

1) Copy assignment operator. Replaces the contents with a copy of the contents of other. Effectively calls c = other.c;.

2) Move assignment operator. Replaces the contents with those of other using move semantics. Effectively calls c = std::move(other.c);.

Parameters

other

-

another container adaptor to be used as source

Return value

*this

Complexity

1,2) Equivalent to that of operator= of the underlying container.
