Concurrently unsafe modifiers

All member functions in this section can only be performed serially. The behavior is undefined in case of concurrent execution of these methods with other (either concurrently safe) methods.

clear

void clear();

Removes all elements from the container.

swap

void swap( concurrent_priority_queue& other );

Swaps contents of *this and other.

Swaps allocators if std::allocator_traits<allocator_type>::propagate_on_container_swap::value is true.

Otherwise if get_allocator() != other.get_allocator() the behavior is undefined.
