template bool operator bool operator = ( HeapType const & rhs ) const Equivalent comparison Returns: True, if both heap data structures are equivalent.template bool operator >= ( HeapType const & rhs ) const.Requirement: the value_compare object of both heaps must match. Priority queues push( ) an object onto a priorityqueue, that object is sorted into the queue according to a function or function object (you can allow the. Returns: Element-wise comparison of heap data structures

Elements can be inserted in any order in queue but only the gr. The element is directly constructed in-place.Įffects: Removes the top element from the priority queue.Įffects: Returns an iterator to the first element contained in the priority queue.Įffects: Returns an iterator to the end of the priority queue. A priority queue is a special type of queue in which each element is associated with a priority and is served according to its priority, value of element itself is considered for priority.If elements with the same priority occur, they are served according to their order in the queue. If you want to iterate over the priority queue to search for whether it contains a value then maybe create a wrapper priority queue and use a hash set to keep track of what you have in the queue. args ) Įffects: Adds a new element to the priority queue. begin () pointer (like vector would do) that you can use to iterate over it.

allocator_type get_allocator ( void ) const Įffects: Returns a const_reference to the maximum element.Įffects: Adds a new element to the priority queue.Ĭomplexity: Logarithmic (amortized).

Template class priority_queue Įffects: Returns true, if the priority queue contains no elements.Įffects: Returns the number of elements contained in the priority queue.Įffects: Returns the maximum number of elements the priority queue can contain.Įffects: Removes all elements from the priority queue.
