  - ### setCancellationController

    public AsyncOperationContext setCancellationController(CancellationController cancellationController)
    A `CancellationController` that the asynchronous operation should look to for whether the operation is canceled.

    This may be `null` if the invoker of the asynchronous operation does not need the ability to cancel. However, note that the `result type` may still be CANCELED; for example, the asynchronous operation may be self-canceling after a timeout.

    Implementations of asynchronous operations must treat this `CancellationController` as observe-only, and they cannot `cancel` it.

    Parameters:
      `cancellationController` - New cancellationController value. Default value is null
    Returns:
      `AsyncOperationContext` instance, for chaining setter calls

  - ### getCancellationController

    public CancellationController getCancellationController()
    A `CancellationController` that the asynchronous operation should look to for whether the operation is canceled.

    This may be `null` if the invoker of the asynchronous operation does not need the ability to cancel. However, note that the `result type` may still be CANCELED; for example, the asynchronous operation may be self-canceling after a timeout.

    Implementations of asynchronous operations must treat this `CancellationController` as observe-only, and they cannot `cancel` it.

    Returns:
      Current cancellationController value. Default value is null
