Examples of org.jboss.cache.config.EvictionAlgorithmConfig

org.jboss.cache.config.EvictionAlgorithmConfig
An interface used to configure an eviction algorithm. Replaces the deprecated {@link org.jboss.cache.config.EvictionPolicyConfig}.
In its most basic form, it is implemented by {@link org.jboss.cache.eviction.EvictionAlgorithmConfigBase}, but more specific eviction policies may subclass {@link org.jboss.cache.eviction.EvictionAlgorithmConfigBase} or re-implementthis interface to provide access to more config variables. @author Manik Surtani (manik AT jboss DOT org) @since 3.0
