Method Summary

Modifier and Type	Method and Description

Method Detail

tryEvict

<C extends EvictionCandidate<A,E>> boolean tryEvict(C evictionCandidate,
                                                    EvictionListener<A,E> evictionListener)

The evict method is called by the EvictionStrategy to eventually evict, by the policy, selected candidate from the internal data structures. It could be the selected evicted candidate cannot be evicted. For example it might be gone at the time when the method is executed. In this case it will indicate this condition by returning false.

Parameters:

evictionCandidate - EvictionCandidate to be evicted

evictionListener - EvictionListener to listen evicted entries

Returns:

true if the candidate was evicted, otherwise returns false
