IFuture.Cancel(Boolean) Method

Definition

Attempts to cancel execution of this task.

[Android.Runtime.Register("cancel", "(Z)Z", "GetCancel_ZHandler:Java.Util.Concurrent.IFutureInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")]
public bool Cancel (bool mayInterruptIfRunning);
[<Android.Runtime.Register("cancel", "(Z)Z", "GetCancel_ZHandler:Java.Util.Concurrent.IFutureInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")>]
abstract member Cancel : bool -> bool

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

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.

Attributes

Remarks

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.
