Interface PriorityLinkedList<E>

All Known Implementing Classes:

PriorityLinkedListImpl

public interface PriorityLinkedList<E>

A type of linked list which maintains items according to a priority and allows adding and removing of elements at both ends, and peeking.
Only size() and isEmpty() are safe to be called concurrently.

Method Summary

Modifier and Type	Method	Description
void	addHead(E e, int priority)
void	addSorted(E e, int priority)
void	addTail(E e, int priority)
void	clear()
boolean	isEmpty()	Returns true if empty, false otherwise. It is safe to be called concurrently.
LinkedListIterator<E>	iterator()
E	poll()
E	removeWithID(java.lang.String listID, long id)
void	setNodeStore(NodeStore<E> supplier)
int	size()	Returns the size of this list. It is safe to be called concurrently.
