Class LIFOQueue<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractQueue<E>

java.util.concurrent.LinkedBlockingDeque<E>

com.jolbox.bonecp.LIFOQueue<E>

Type Parameters:

E -

All Implemented Interfaces:

Serializable, Iterable<E>, Collection<E>, BlockingDeque<E>, BlockingQueue<E>, TransferQueue<E>, Deque<E>, Queue<E>

public class LIFOQueue<E>
extends LinkedBlockingDeque<E>
implements TransferQueue<E>

An implementation that uses LinkedBlockingDeque internally to hide the difference between this version and a BoundedLinkedTransferQueue (when used in FIFO mode). This changes the queue so that every insert function is inserted at the head of the list.
