std::queue<T,Container>::swap: std::queue<T,Container>::swap

NAME

std::queue<T,Container>::swap - std::queue<T,Container>::swap

Synopsis

void swap( queue& other ) noexcept(/* see below */); (since C++11)

Exchanges the contents of the container adaptor with those of other. Effectively calls using std::swap; swap(c, other.c);

Parameters

other - container adaptor to exchange the contents with

Return value

(none)

Exceptions

noexcept specification:
noexcept(noexcept(swap(c, other.c))) (until C++17)
In the expression above, the identifier swap is looked up in the same manner as the one used by the C++17 std::is_nothrow_swappable trait.
noexcept specification: (since C++17)
noexcept(std::is_nothrow_swappable<Container>::value)

Complexity

Same as underlying container (typically constant)
