Interface Summary

Interface	Description
WeakSoftTable.RemovableReference	Implemented by classes to permit copying instances into reference queues when they are added to the table and to remove them from the table when the references are cleared.
WeakTable.KeyGCHandler	Handler for clients that need to know when a key is removed from the table because it has been collected.

Class Summary

Class	Description
SoftCache<K,V>	Map of keys to softly-referenced values which automatically removes mappings for garbage-collected values.
WeakIdentityMap<K,V>	Identity-based weak hash map.
WeakKeyReference<T>	A weak reference to a key in a table.
WeakSoftTable	A table that maps a key containing a weak reference to one or more values containing soft references.
WeakSoftTable.SoftValue	A value that maintains a soft reference to an object.
WeakSoftTable.WeakKey	A key that maintains a weak reference to an object which should be compared by object identity.
WeakTable	This class is designed to allow weakly held keys to weakly held objects.
