• getExecutor

  @Nullable
  public AsyncTaskExecutor getExecutor()

  Return the AsyncTaskExecutor to use for concurrent handling, or null if none specified.

• onTimeout

  public void onTimeout​(Callable<V> callback)

  Register code to invoke when the async request times out.

  This method is called from a container thread when an async request times out before the Callable has completed. The callback is executed in the same thread and therefore should return without blocking. It may return an alternative value to use, including an Exception or return RESULT_NONE.

• onError

  public void onError​(Callable<V> callback)

  Register code to invoke for an error during async request processing.

  This method is called from a container thread when an error occurred while processing an async request before the Callable has completed. The callback is executed in the same thread and therefore should return without blocking. It may return an alternative value to use, including an Exception or return RESULT_NONE.

• onCompletion

  public void onCompletion​(Runnable callback)
