cancel back to summary

cancel	back to summary
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`. Annotations @Override

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.
