Question

In ActionScript3, how do you get a reference to an object’s class?

Answer 1

You can use the constructor property if your object has been created from a class (from the docs: ‘If an object is an instance of a class, the constructor property holds a reference to the class object. If an object is created with a constructor function, the constructor property holds a reference to the constructor function.’):

var classRef:Class = myObject.constructor as Class; 

Or you can use flash.utils.getQualifiedClassName() and flash.utils.getDefinitionByName() (not a very nice way since this entails unnecessary string manipulation in the implementations of these library functions):

var classRef:Class = getDefinitionByName(getQualifiedClassName(myObject)) as Class;
