Class DefaultTaskContext

java.lang.Object

org.codehaus.griffon.runtime.tasks.DefaultTaskContext

All Implemented Interfaces:

TaskContext, PropertyChangeListener, EventListener

public class DefaultTaskContext
extends Object
implements TaskContext, PropertyChangeListener

Wraps the execution of a Task which is governed by a DefaultTaskWorker. This context holds adds listener support. It registers itself as PropertyChangeListener to the DefaultTaskWorker object and translates the UIThreadWorker events to TaskEvents.

Each execution can be identified by a growing id. For retrieving task execution properties it delegates to the wrapped DefaultTaskWorker.
