find if class is descendant from...?
Mar 29th, 2008, 12:26pm  
Is there an easy way to find a class descends from another class? I traverse through a list with objects that all implement the same interface. I want to filter out the few that descent from a particular abstract class. I did find the 'getSuperclass' method but that only returns the direct superclass, while the abstract one I want to check is sometimes super, and sometimes the super of the super. I've now just put a cast in a try..catch, it works but I just don't like the look of it.

if (object instanceOf abstractClass){
//do something
}

try this, replacing object and abstractClass with your stuff of course =)
