void |
cancelled(TaskEvent<Void> event)
Called after the Task's
cancelled method
is called. |
void |
doInBackground(TaskEvent<Void> event)
Called just before the Task's
doInBackground method is called, i.e. |
void |
failed(TaskEvent<Throwable> event)
Called after the Task's
failed completion
method is called. |
void |
finished(TaskEvent<Void> event)
Called after the Task's
finished method is called. |
void |
interrupted(TaskEvent<InterruptedException> event)
Called after the Task's
interrupted method is called. |
void |
process(TaskEvent<List<V>> event)
Called each time the Task's
process method is called. |
void |
succeeded(TaskEvent<T> event)
Called after the Task's
succeeded
completion method is called. |

returned by the Task's get
method, i.e. the value that
is computed by SwingWorker.doInBackground()
