Description copied from class: Cache

Called when an entry is being aged out of the cache. Can be overriden by subclasses that want to take some action when an entry is being aged out of the cache due to overflow. It is only called when an entry is aged out due to overflow, not when entries are explicitly removed or the cache is cleared. It is called before the entry is removed from the cache.

Overrides:

overflow in class Cache

Parameters:

key - the entry key

value - the entry value
