Examples of EventMetadata

org.apache.isis.applib.services.publish.EventMetadata
Standard metadata about an event to be published.
This is a class rather than an interface so that it may be easily extended in the future. @see EventPayload
org.apache.tez.runtime.api.impl.EventMetaData
Class that encapsulates all the information to identify the unique object that either generated an Event or is the recipient of an Event.
