Model.getGenConstrExpA()

Retrieve the data associated with a general constraint of type EXPA. 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 addGenConstrExpA for a description of the semantics of this general constraint type.

Arguments:

genc: The general constraint object.

Return value:

A tuple (xvar, yvar, a) that contains the data associated with the general constraint:

xvar (Var): The variable.

yvar (Var): The variable.

a (float): The base of the function.

Example usage:

  # y = 3^x
  expaconstr = model.addGenConstrExpA(x, y, 3.0, "expa")
  model.update()
  (xvar, yvar, a) = model.getGenConstrExpA(expaconstr)
