Retrieve the data associated with a general constraint of type POLY. Calling this method for a general constraint of a different type leads to an exception. You can query the GenConstrType attribute to determine the type of the general constraint.
See also addGenConstrPoly for a description of the semantics of this general constraint type.
genc: The general constraint object.
A tuple (xvar, yvar, p) that contains the data of the general constraint:
xvar (Var): The variable.
yvar (Var): The variable.
p (list of float): The coefficients for polynomial function.
(xvar, yvar, p) = model.getGenConstrPoly(model.getGenConstrs())
