Class CircularList

java.lang.Object

com.mchange.util.impl.CircularList

All Implemented Interfaces:

java.lang.Cloneable

public class CircularList
extends java.lang.Object
implements java.lang.Cloneable

CircularList is a list class. Objects can be added at the beginning or end; they may be enumerated through forwards or backwards; they may be retrieved directly or by index from the front or rear. CircularLists can also be enumerated endlessly. If the list contains any elements at all, an "unterminated" Enumeration will always claim to have more elements... when it's done enumerating, it will start over again. The default Enumeration is of the usual, terminated variety, however.

This class is a completely UNSYNCHRONIZED implementation class. Synchronize on calls where necessary.
