Class NoClusteredResourceStateHandler

java.lang.Object
  org.cruxframework.crux.core.server.rest.state.NoClusteredResourceStateHandler

All Implemented Interfaces:

ResourceStateHandler

public class NoClusteredResourceStateHandler
extends Object
implements ResourceStateHandler

It is a very basic implementation for ResourceStateHandler interface that is designed to run only on NO CUSTERED environment. It uses a simple LRUMap to keep the resource state into local machine's memory. To configure the cache, you can create a file named NoClusteredCacheConfig.properties and configure the property maxNumberOfEntries to set the max number of entries into the map.
