Class WeakArrayList<T>

java.lang.Object
  nl.knowledgeplaza.util.WeakArrayList<T>

All Implemented Interfaces:

Iterable<T>, Collection<T>, List<T>

public class WeakArrayList<T>
extends Object
implements List<T>

An arraylist storing its contents using WeakReferences. A dead reference returns null, therefore storing null as an explicit value is not allowed. The user should call "garbageCollect" on a some what regular basis to make sure the dead wood gets cleaned out. However iterator(), removeAll() and retainAll() also do a garbageCollect prior or after the operation.
