public interface EvictionStrategy<A,E extends Evictable,S extends EvictableStore<A,E>>

Interface for eviction implementations to evict EvictableStore implementations as specified EvictionPolicyEvaluator.

Method Summary

int	evict(S evictableStore, EvictionPolicyEvaluator<A,E> evictionPolicyEvaluator, EvictionChecker evictionChecker, EvictionListener<A,E> evictionListener) Does eviction if eviction is required by given EvictionChecker.

Method Detail

          EvictionPolicyEvaluator<A,E> evictionPolicyEvaluator,
          EvictionChecker evictionChecker,
          EvictionListener<A,E> evictionListener)

Does eviction if eviction is required by given EvictionChecker.

Parameters:

evictableStore - Store that holds Evictable entries

evictionPolicyEvaluator - EvictionPolicyEvaluator to evaluate EvictionPolicy on entries

evictionChecker - EvictionChecker to make a decision about if eviction is required or not. If you want evict anyway, you can use EvictionChecker.EVICT_ALWAYS

evictionListener - EvictionListener to listen evicted entries
