ResourceCache

public class ResourceCacheImpl
extends java.lang.Object
implements ResourceCache

Default implementation of the resource cache for the default ResourceManager. The cache uses a least recently used (LRU) algorithm, with a maximum size specified via the resource.manager.cache.size property (idenfied by the RuntimeConstants.RESOURCE_MANAGER_DEFAULTCACHE_SIZE constant). This property get be set to 0 or less for a greedy, unbounded cache (the behavior from pre-v1.5).
