# std::priority_queue::swap

From cppreference.com
< cpp‎ | container‎ | priority queue

[edit template]

void swap( priority_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); swap(comp, other.comp);

### [edit] Parameters

other | - | container adaptor to exchange the contents with

### [edit] Return value

(none)

### [edit] Exceptions

In the noexcept expressions below, the identifier `swap` is looked up in the same manner as the C++17 std::is_nothrow_swappable trait. `noexcept` specification: noexcept(noexcept(swap(c, other.c)) && noexcept(swap(comp, other.comp))) | (until C++17)
`noexcept` specification: noexcept(std::is_nothrow_swappable<Container>::value && std::is_nothrow_swappable<Compare>::value) | (since C++17)

### [edit] Complexity

Same as underlying container (typically constant)

### [edit] See also

std::swap(std::priority_queue) | specializes the std::swap algorithm (function template) [edit]
