Method Detail

cancel

void cancel()

Cancels this operation or signal. This will end the work that would have been done and notify all consumers of the operation that a result will not be returned. It is not an error to call this method on an operation that has already completed or already been cancelled. This method will not block or throw non-fatal exceptions.
