Question

In Action Script 3, you can write a class that defines a dynamic object (MovieClip and Object are two examples), this objects can be modified in run-time. What I want to know if is there some way (in run-time, of course) to know if certain object is dynamic or not.

PS: Without making something like this:

function isDynamic(object) {     try {         object.newProperty = 'someValue'     } catch (e) {         return false     }     return true } 

Answer 1

CookieOfFortune has the right idea, but unfortunately the code itself has problems, isDynamic is an attribute, and the returned value will be a XMLList with a value of a String that reflects a true or false value, not a child node that directly returns a Boolean. It should look more like this:

function isDynamic(object) : Boolean {     var type:XML = describeType(object);     return [e-mail]() == 'true'; }
