org.kepler.objectmanager.cache

Class ActorCacheObject

java.lang.Object

org.kepler.objectmanager.cache.CacheObject

org.kepler.objectmanager.cache.ActorCacheObject

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, CacheObjectInterface

public class ActorCacheObject
extends CacheObject
implements java.io.Externalizable

Modified by Dan Higgins, Aug 9, 2007 to avoid instantiating all the actors when the ActorCacheObject is created. This is done be avoiding creating the ActorMetadata object and using the MoML parser. Instead a DOM parser is used to pull out just a few of parameters in the kar files MoML description of the actor, and the xml saved with the ActorCacheObject is exactly that in the kar file.
