public interface MetaDataEvent
extends GenericMetaDataEvent<EventMetaData,java.lang.Object>, org.refcodes.mixin.MetaDataAccessor<EventMetaData>, Event

An MetaDataEvent is published by an Observable and is consumed by zero to many Observer instances. The MetaDataEvent object describes what the Observable is publishing in more detail than a plain GenericActionEvent.

An MetaDataEvent provides Meta-Data describing the GenericActionEvent in more detail and a source being the origin of the MetaDataEvent.
