Class TaskListener.Adapter<T,V>

java.lang.Object

org.jdesktop.application.TaskListener.Adapter<T,V>

Type Parameters:

T - the result type returned by this SwingWorker's doInBackground and get methods

V - the type used for carrying out intermediate results by this SwingWorker's publish and process methods

All Implemented Interfaces:

TaskListener<T,V>

Enclosing interface:

TaskListener<T,V>

public static class TaskListener.Adapter<T,V>
extends Object
implements TaskListener<T,V>

Convenience class that stubs all of the TaskListener interface methods. Using TaskListener.Adapter can simplify building TaskListeners.

Method Detail

doInBackground

public void doInBackground(TaskEvent<Void> event)

Description copied from interface: TaskListener

Called just before the Task's doInBackground method is called, i.e. just before the task begins running. The event's source is the Task and its value is null.

Specified by:

doInBackground in interface TaskListener<T,V>

Parameters:

event - a TaskEvent whose source is the Task object, value is null

See Also:

SwingWorker.doInBackground(), EventObject.getSource()

process

public void process(TaskEvent<List<V>> event)

Description copied from interface: TaskListener

Called each time the Task's process method is called. The value of the event is the list of values passed to the process method.

Specified by:

process in interface TaskListener<T,V>

Parameters:

event - a TaskEvent whose source is the Task object and whose value is a list of the values passed to the Task.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's succeeded completion method is called. The event's value is the value returned by the Task's get method, i.e. the value that is computed by SwingWorker.doInBackground().

Specified by:

succeeded in interface TaskListener<T,V>

Parameters:

event - a TaskEvent whose source is the Task object, and whose value is the value returned by Task.get().

See Also:

Task.succeeded(T), EventObject.getSource(), TaskEvent.getValue()

failed

public void failed(TaskEvent<Throwable> event)

Description copied from interface: TaskListener

Called after the Task's failed completion method is called. The event's value is the Throwable passed to Task.failed().

Specified by:

failed in interface TaskListener<T,V>

Parameters:

event - a TaskEvent whose source is the Task object, and whose value is the Throwable passed to Task.failed().

See Also:

Task.failed(java.lang.Throwable), EventObject.getSource(), TaskEvent.getValue()

cancelled

public void cancelled(TaskEvent<Void> event)

Description copied from interface: TaskListener

Called after the Task's cancelled method is called. The event's source is the Task and its value is null.

Specified by:

cancelled in interface TaskListener<T,V>

Parameters:

event - a TaskEvent whose source is the Task object, value is null

See Also:

Task.cancelled(), SwingWorker.get(), EventObject.getSource()

interrupted

public void interrupted(TaskEvent<InterruptedException> event)

Description copied from interface: TaskListener

Called after the Task's interrupted method is called. The event's source is the Task and its value is the InterruptedException passed to Task.interrupted().

Specified by:

interrupted in interface TaskListener<T,V>

Parameters:

event - a TaskEvent whose source is the Task object, and whose value is the InterruptedException passed to Task.interrupted().

See Also:

Task.interrupted(java.lang.InterruptedException), EventObject.getSource(), TaskEvent.getValue()

finished

public void finished(TaskEvent<Void> event)

Description copied from interface: TaskListener

Called after the Task's finished method is called. The event's source is the Task and its value is null.

Specified by:

finished in interface TaskListener<T,V>

Parameters:

event - a TaskEvent whose source is the Task object, value is null.

Task.interrupted(java.lang.InterruptedException), EventObject.getSource()
