Thomas Neidhart commented on COLLECTIONS-467:
---------------------------------------------
You may take a look at the PassiveExpiringMap decorator which has been added
recently to the trunk.
For the other things, patches are, as always, very welcome. Regarding the
callback, what do you think about a listener interface? Callbacks as protected
methods always require subclassing, which may not always be useful / possible.

> If you use LRUMap with objects that require doing some disposal when they are
> dropped (eg. close()) and you hold these objects only in LRUMap, you cannot
> do it with current implementation. I propose to add onRemove() and onAdd()
> methods to the implementation, so that you can create anonymous inherited
> class and be able to react to these events.
