Interface CapacityEvictionPolicyData

All Superinterfaces:

Comparable<CapacityEvictionPolicyData>

All Known Implementing Classes:

LFUCapacityEvictionPolicyData, LRUCapacityEvictionPolicyData, NullCapacityEvictionPolicyData

public interface CapacityEvictionPolicyData
extends Comparable<CapacityEvictionPolicyData>

It is important that implementations of CapacityEvictionPolicyData#compareTo(org.terracotta.cache.evictor.CapacityEvictionPolicyData) safely handle comparison with a null object. Null objects represent untouched values, hence a.compareTo(null) should by contract return a positive value since untouched values should always be evicted first.
