QueueElement (Mallet 2 API)

All Known Implementing Classes:

public interface QueueElement

Created by IntelliJ IDEA. User: pereira Date: Jun 18, 2005 Time: 7:31:08 PM Queue elements have a priority, and a queue position. Lower-priority elements are closer to the front of the queue. The queue position is set by the queue implementation, and should not be changed outside the queue implementation.
