Alex,
Interesting problem. Can you send me some code to take a look at it? Perhaps one of
the Node derivered classes in J3D has a synchronized version of hashCode()...?
To achieve what you are trying to do I would store the what-to-do-method in the "user
data" for the node - that way, given a node you do not have to do any hash table
lookups, but can jump straight to the method. setUserData(...) etc.
Sincerely,
Daniel Selman
