Note: It is not safe to call any of CacheLIRS's method from withing this callback. Any such call might result in undefined behaviour and Java level deadlocks.

The method may be called twice for the same key (first if the entry is resident, and later if the entry is non-resident).

Parameters:

key - the evicted item's key

value - the evicted item's value or null if non-resident

cause - the cause of the eviction
