QUESTION: Is there a way to listen to class name changes

I figured it out -- using "update" local hook

_**updated(property: any, value: any, prevValue: any) {
                   for (let i = 0; i < value.models.length; i++) {
                        log.debug('$$$$ :', value.models[i].attributes.name);
                    }
                },**_

I am using " value.models[i].attributes.name" -- is there a better way such as "getClasses" function or something like this?
