public class ReferenceCleaner

extends Object

ReferenceCleaner is used to remove entries from collections which use soft or weak references. To use, simply register reference with this ReferenceCleaner.queue, e.g., by supplying this queue as an argument to the reference constructor. The reference should implement ReferenceCleaner.Cleanable, and its ReferenceCleaner.Cleanable.cleanUp() method will be called, e.g., to remove the reference from a collection or map.
