public class MCREvent
extends Hashtable<String,Object>

Represents an event that occured in the MyCoRe system. Events are of a predefined event type like create, update, delete and an object type like object or file. They can be handled by MCREventHandler implementations. Events are automatically created by some MyCoRe components and are forwarded to the handlers by MCREventManager.
