Examples of com.threerings.whirled.data.SceneUpdate

com.threerings.whirled.data.SceneUpdate
Used to encapsulate updates to scenes in such a manner that updates can be stored persistently and sent to clients to update their own local copies of scenes.

            _updates.add(update);
            return;
        }


        // otherwise make sure this update conforms to our update sequence
        SceneUpdate last = _updates.get(_updates.size()-1);
        int expVersion = last.getSceneVersion() + last.getVersionIncrement();
        int gotVersion = update.getSceneVersion();
        if (gotVersion > expVersion) {
            log.warning("Update continuity broken, flushing list [got=" + update +
                        ", expect=" + expVersion + ", ucount=" + _updates.size() + "].");
            _updates.clear(); // flush out our old updates, fall through and add this one
