If you need to do this in a few places, I would create a class like this:
public abstract class RepeatingAsyncMethod<T> implements AsyncCallback<T> {
public abstract void sendAsyncRequest();
public abstract boolean shouldRepeat(T result);
public abstract void onComplete(T lastResult);
@Override
public void onSuccess(T result) {
if (shouldRepeat(result)) {
sendAsyncRequest();
}
else {
onComplete(result);
}
}
}
and then make an implementation that calls whatever RPC method you need to
call in "sendAsyncRequest", passing "this" as the callback. Then you can
implement shouldRepeat to determine whether or not you should repeat.
If you have parameters you need to pass to your RPC, you could put them in
the constructor of your subclass and send them each time in
sendAsyncRequest.
