order_total class and class redeclaration

[s_p_ike]

Hello, I'd like to use order_total class in function function process_button() in a payment module.

If I simply use it, then when it's called later in the script (in the normal ZC flow), I obtain a 'cannot redeclare class... (all the classes initialized by order total modules).

How to avoid this?

Is it possible to 'destroy' a class declaration after having used it?

Thank you

Solved, I duplicated the order_total class (renaming it, obviously) then I removed from its code the 'sub' classes declaration (plus other things I didn't need) and now it works (obviously I call my own order_total clas).
