Retrieve the data of a general constraint of type OR. Calling this function for a general constraint of different type leads to an exception. You can query the GenConstrType attribute to determine the type of the general constraint.
See also addGenConstrOr for a description of the semantics of this general constraint type.
genconstr: The general constraint object of interest.
A tuple (resvar, vars) that contains the data of the general constraint:
resvar (Var): Resultant variable of OR constraint.
vars (list of Var): Operand variables of OR constraint.
(resvar, vars) = model.getGenConstrOr(model.getGenConstrs())
