All Known Implementing Classes:

PopupView.AttachmentInfoCallback

public interface CallbackListener<T>

Implement this interface to handle the returned result from an asynchronous call. Note that the onCallback method will still be called in the event of an error. In this case onError will be called first.

Since:

void	onCallback(T objs) Handles the result of the call.
void	onError(Throwable e) Handles the result when the call failed.
