Interface DeferredResponse<T>

Type Parameters:
T - response type expected (Void if no object, but null is expected)

public interface DeferredResponse<T>
Interface for receiving deferred/async responses.

GDS-ng implementations which are not capable of asynchronous or delayed processing of responses are expected to synchronously invoke the onResponse(Object) and - optionally - onException(Exception) methods within the method call.

  • Method Summary

    Modifier and Type
    Method
    Description
    default void
    Exception received when receiving or processing the response.
    default void
    onResponse(T response)
    Called with successful response.
  • Method Details

    • onResponse

      default void onResponse(T response)
      Called with successful response.
      Parameters:
      response - response object, or null if there is no response, but the request completed successfully
    • onException

      default void onException(Exception exception)
      Exception received when receiving or processing the response.

      The default implementation only logs the exception on debug level.

      For GDS-ng implementations that can only perform synchronous processing, it is implementation-defined whether or not this method is called, or if the exception is thrown directly from the invoked method.

      Parameters:
      exception - exception received processing the response
