Re: JESS: User function.

[Gang Liu]

Jess doesn't do anything to create
additional instances of your Userfunction class.

:) That is what I want to know. I just want to double confirm Jess only create one instance of my userfunction if I only add it once by:
Rete r = new Rete();
r.addUserfunction(new myUserfunction());

thanks

Not sure what you're asking. Jess doesn't do anything to create
additional instances of your Userfunction class. The function is only
available in the Rete object you add it to, so you could have one per
Rete object, or you could use a single one and share it among many
Rete objects. But in any case, however many you create, that's all
there are.
