RE: [flexcoders] Beta 2: Evaluating interfaces

[Gordon Smith]

'is' can only be used to test *instances* of classes that implement interfaces. You don't use it with the class itself.   So...   function checkImp(className:Class):Boolean {     return new className() is IMyInterface; }   will work.   You could also use describeType(className) and iterate over the <implementsInterface> child tags, but this would be much more expensive.   - Gordon   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Scott Langeberg Sent: Wednesday, March 29, 2006 1:29 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Beta 2: Evaluating interfaces   Wondering if there is ability to find out if a Class implements an interface? As in: function checkImp(className:Class): Boolean {    return (className is IMyInterface); } I'm using the PopUpManager internally, and want to check that whatever gets passed in implements my interface, first.
