方法详细资料

getTask

TimerTask getTask()

cancel

boolean cancel()

Attempts to cancel execution of this task. This attempt will fail if the task has already completed, has already been cancelled, or could not be cancelled for some other reason. If successful, and this task has not started when cancel is called, this task should never run. If the task has already started, then the mayInterruptIfRunning parameter determines whether the thread executing this task should be interrupted in an attempt to stop the task.

After this method returns, subsequent calls to isDone() will always return true. Subsequent calls to isCancelled() will always return true if this method returned true.

isCancelled

boolean isCancelled()

Returns true if this task was cancelled before it completed normally.

返回:

true if this task was cancelled before it completed

isDone

boolean isDone()

Returns true if this task completed. Completion may be due to normal termination, an exception, or cancellation -- in all of these cases, this method will return true.

返回:

true if this task completed
