Method Detail

doInBackground
public void doInBackground(TaskEvent<java.lang.Void> event)
Description copied from interface:TaskListener
Called just before the Task'sdoInBackground
method is called, i.e. just before the task begins running. Theevent's
source is the Task and its value is null.- Specified by:
doInBackground
in interfaceTaskListener<T,V>
- Parameters:
event
- a TaskEvent whose source is theTask
object, value is null- See Also:
SwingWorker.doInBackground()
,EventObject.getSource()
-
process
public void process(TaskEvent<java.util.List<V>> event)
Description copied from interface:TaskListener
Called each time the Task'sprocess
method is called. The value of the event is the list of values passed to the process method.- Specified by:
process
in interfaceTaskListener<T,V>
- Parameters:
event
- a TaskEvent whose source is theTask
object and whose value is a list of the values passed to theTask.process()
method- See Also:
SwingWorker.doInBackground()
,Task.process(java.util.List<V>)
,EventObject.getSource()
,TaskEvent.getValue()
-
succeeded
public void succeeded(TaskEvent<T> event)
Description copied from interface:TaskListener
Called after the Task'ssucceeded
completion method is called. The event's value is the value returned by the Task'sget
method, i.e. the value that is computed bySwingWorker.doInBackground()
.- Specified by:
succeeded
in interfaceTaskListener<T,V>
- Parameters:
event
- a TaskEvent whose source is theTask
object, and whose value is the value returned byTask.get()
.- See Also:
Task.succeeded(T)
,EventObject.getSource()
,TaskEvent.getValue()
-
failed
public void failed(TaskEvent<java.lang.Throwable> event)
Description copied from interface:TaskListener
Called after the Task'sfailed
completion method is called. The event's value is the Throwable passed toTask.failed()
.- Specified by:
failed
in interfaceTaskListener<T,V>
- Parameters:
event
- a TaskEvent whose source is theTask
object, and whose value is the Throwable passed toTask.failed()
.- See Also:
Task.failed(java.lang.Throwable)
,EventObject.getSource()
,TaskEvent.getValue()
-
cancelled
public void cancelled(TaskEvent<java.lang.Void> event)
Description copied from interface:TaskListener
Called after the Task'scancelled
method is called. Theevent's
source is the Task and its value is null.- Specified by:
cancelled
in interfaceTaskListener<T,V>
- Parameters:
event
- a TaskEvent whose source is theTask
object, value is null- See Also:
Task.cancelled()
,SwingWorker.get()
,EventObject.getSource()
-
interrupted
public void interrupted(TaskEvent<java.lang.InterruptedException> event)
Description copied from interface:TaskListener
Called after the Task'sinterrupted
method is called. Theevent's
source is the Task and its value is the InterruptedException passed toTask.interrupted()
.- Specified by:
interrupted
in interfaceTaskListener<T,V>
- Parameters:
event
- a TaskEvent whose source is theTask
object, and whose value is the InterruptedException passed toTask.interrupted()
.- See Also:
Task.interrupted(java.lang.InterruptedException)
,EventObject.getSource()
,TaskEvent.getValue()
-
finished
public void finished(TaskEvent<java.lang.Void> event)
Description copied from interface:TaskListener
Called after the Task'sfinished
method is called. Theevent's
source is the Task and its value is null.- Specified by:
finished
in interfaceTaskListener<T,V>
- Parameters:
event
- a TaskEvent whose source is theTask
object, value is null.- See Also:
Task.interrupted(java.lang.InterruptedException)
