TQueue implements a queue. The typical queue operations are implemented, which include {@link enqueue()}, {@link dequeue()} and {@link peek()}. In addition, {@link contains()} can be used to check if an item is contained in the queue. To obtain the number of the items in the queue, check the {@link getCount Count} property.
