Class DecisionCacheLocator

org.jboss.security.xacml.locators.cache.CacheLocator

org.jboss.security.xacml.locators.cache.DecisionCacheLocator

All Implemented Interfaces:

AbstractLocator, ContextMapOp

public class DecisionCacheLocator
extends CacheLocator

A Cache that stores decisions made on requests. NOTE: Configure this if you know that your requests are going to closely match each other. If the requests are going to be independent, then the cache will just grow. Since the cache implementation uses a java.util.WeakHashMap, the cache is going to be JDK controlled under the Garbage Collector.
