public boolean cancel(boolean mayInterruptIfRunning)

Implements java.util.concurrent.Future.cancel.

Doc from java.util.concurrent.Future.cancel.

Attempts to cancel execution of this task. This method has no effect if the task is already completed or cancelled, or could not be cancelled for some other reason. Otherwise, if 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 (when known by the implementation) is interrupted in an attempt to stop the task.

The return value from this method does not necessarily indicate whether the task is now cancelled; use isCancelled.

Parameters
mayInterruptIfRunning:boolean

true if the thread executing this task should be interrupted (if the thread is known to the implementation); otherwise, in-progress tasks are allowed to complete

Returns:boolean

false if the task could not be cancelled, typically because it has already completed; true otherwise. If two or more threads cause a task to be cancelled, then at least one of them returns true. Implementations may provide stronger guarantees.

public boolean isCancelled()

public boolean isDone()

Implements java.util.concurrent.Future.isDone.

Doc from java.util.concurrent.Future.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.

Returns:boolean

true if this task completed
