com.mysql.clusterj.core.spi.ValueHandler
ValueHandler is the interface that must be implemented for core components to access values of a managed instance.

        if (instance instanceof ValueHandler) {
            return (ValueHandler)instance;
        } else if (instance instanceof DynamicObject) {
            return (ValueHandler)((DynamicObject)instance).delegate();
        } else {
            ValueHandler handler = (ValueHandler)
                    Proxy.getInvocationHandler(instance);
            return handler;
        }
    }
