cancel

public boolean cancel(boolean mayInterruptIfRunning)

Description copied from interface: Call

Cancels a synchronous execution and calls the most recent cancelCallback that was registered. The execution is still allowed to complete and return a result. In addition to using a cancelCallback, executions can cooperate with cancellation by checking ExecutionContext.isCancelled().

cancel in interface Call<R>

Parameters:

mayInterruptIfRunning - whether the execution should be interrupted

Returns:

whether cancellation was successful or not. Returns false if the execution was already cancelled or completed.

isCancelled

Returns whether the call has been cancelled.
