All Implemented Interfaces:

Serializable

public class ModuleEvent
extends EventObject

An event from the Runtime describing a module lifecycle change.

ModuleEvent objects are delivered to SynchronousModuleListeners and ModuleListeners when a change occurs in a module's lifecycle. A type code is used to identify the event type for future extendability.
