class.__subclasses__() trick

[Gregor]

hi,

just saw your project on reddit. looks really nice. i needed to make a
similar
framework which involved nodes and connecting them. i found this
little trick
to register nodes. maybe you can use it in your project.

cheers gregor

class Node(object):
pass

class Mix(Node):
pass

class Simplex(Node):
pass

def node_registry():
nodes = {}
for n in Node.__subclasses__():
nodes[n.__name__] = n
return nodes

if __name__ == "__main__":
print node_registry()

That's a nice idea, I'll probably use it, thanks! :)
