java - Set complex constrain - Choco

Question

I have a constrain in this format:

(1 + x*y/z*m)*(2/x*y) - 10 = 0

How can I add this constraint?

IntConstraintFactory class provide a method called arithm to add simpler constraints like this one:

//x + y > 10
IntVar x = VariableFactory.bounded("X", 0, 5, solver);
IntVar y = VariableFactory.bounded("Y", 0, 5, solver);
IntConstraintFactory.arithm(x,"+",y,">",10)

but it's format is fixed.
