PriorityQueue (const Compare &compare=Compare(), const Sequence &sequence=Sequence())
template
PriorityQueue (Iterator begin, Iterator end, const Compare &compare=Compare(), const Sequence &sequence=Sequence())
void erase_one (const T &t)
erase_one - Erase one element from the queue, regardless of its position.
void reheapify ()
reheapify - If an element in the queue has changed in a way that affects its standing in the comparison function, the queue's internal state becomes invalid.
void clear ()
clear - Erase all elements from the queue.

◆ clear()

template<class T , class Sequence = std::vector, class Compare = std::less<typename Sequence::value_type>>

clear - Erase all elements from the queue.

◆ erase_one()

template<class T , class Sequence = std::vector, class Compare = std::less<typename Sequence::value_type>>

erase_one - Erase one element from the queue, regardless of its position.

This operation performs a linear search to find an element equal to t, but then uses all logarithmic-time algorithms to do the erase operation.

◆ reheapify()

template<class T , class Sequence = std::vector, class Compare = std::less<typename Sequence::value_type>>

reheapify - If an element in the queue has changed in a way that affects its standing in the comparison function, the queue's internal state becomes invalid.

Calling reheapify() resets the queue's state, making it valid again. This operation has time complexity proportional to the number of elements in the queue, so don't plan to use it a lot.
