Haxe Reflection - Subclasses and Interfaces

Question

I can use the Haxe Type Class to reflect an object's class e.g.

getClass<T> (o:T):Class<T>

Is there a way to check whether a given object implements an interface or is a subclass of another class?

Answer 1

You can use Std.is:

class Subclass extends OriginalClass implements IMyInterface {}

var myObj = new Subclass();

var isClass = Std.is(myObj, OriginalClass);      // returns true
var isSubclass = Std.is(myObj, Subclass);        // also returns true
var isInterface = Std.is(myObj, IMyInterface);   // also returns true

Will return "true" if the second argument is the class of the object, one of its parent classes, or an interface it implements.
