Sounds more like you would want an implementation that looked like:
class CollectionLoadingCallback<T> implements AsyncCallback<T> {
private final Collection<T> col;
public CollectionLoadingCallback(Collection<T> col) {
this.col = col;
}
public void onSuccess(T result) {
col.add(result);
}
...
}
Of course, I'm sure you'd want another callback to actually know when
the value was received, but the general idea above would work.
