Interface FeedClient.ResultCallback

All Known Implementing Classes:
SimpleLoggerResultCallback
Enclosing interface:
FeedClient
public static interface FeedClient.ResultCallback
This callback is executed when new results are arriving or an error occur. Don't do any heavy lifting in this thread (no IO, disk, or heavy CPU usage). This call back will run in a different thread than your main program so use e.g. AtomicInteger for counters and follow general guides for thread-safe programming. There is an example implementation in class SimpleLoggerResultCallback.

    • onEndpointException

      default void onEndpointException(FeedEndpointException exception)

This callback is intended for application level monitoring (logging, metrics, altering etc). Document specific errors will be reported back through onCompletion(String, Result).
      Parameters:
      exception - an exception specifying endpoint and cause. See FeedEndpointException for details.
