Hi! First sorry I am a beginner ;-( What I want to do is: automatically instantiate subclasses of a given class, say, A. class A end class A1 < A end class A2 <A end So I want to know the names of A subclasses: A1 and A2. Then instantiate via reflection. Is it possible? Using ObjectSpace it is possible to know all the instantiated objects of a class. But here no objects yet. Thanks a lot. -- Posted via http://www.ruby-forum.com/.
