org.codehaus.griffon.runtime.tasks
[Java] Class DefaultTaskContext

java.lang.Object
  org.codehaus.griffon.runtime.tasks.DefaultTaskContext
All Implemented Interfaces:
PropertyChangeListener, TaskContext
public class DefaultTaskContext
extends Object

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.
