Examples of EvictionPolicy

com.hazelcast.config.EvictionPolicy
org.apache.commons.cache.EvictionPolicy
org.jboss.cache.eviction.EvictionPolicy
Generic eviction policy interface.
None of the Eviction classes are thread safe. It is assumed that an individual instance of an EvictionPolicy/ EvictionAlgorithm/EvictionQueue/EvictionConfiguration are only operated on by one thread at any given time. @author Ben Wang 2-2004 @author Daniel Huang - dhuang@jboss.org - 10/2005 @deprecated please use {@link EvictionActionPolicy} instead.
