ortools.constraint_solver.pywrapcp.Constraint Class Reference

Detailed Description

A constraint is the main modeling object. It provides two methods:
  - Post() is responsible for creating the demons and attaching them to
    immediate demons().
  - InitialPropagate() is called once just after Post and performs
    the initial propagation. The subsequent propagations will be performed
    by the demons Posted during the post() method.

◆ InitialPropagateWrapper()

ortools.constraint_solver.pywrapcp.Constraint.InitialPropagateWrapper ( self)
This method performs the initial propagation of the
constraint. It is called just after the post.

Reimplemented in ortools.constraint_solver.pywrapcp.Pack, ortools.constraint_solver.pywrapcp.PyConstraint, and ortools.constraint_solver.pywrapcp.TypeRegulationsConstraint.

ortools.constraint_solver.pywrapcp.Constraint.Post ( self)
This method is called when the constraint is processed by the
solver. Its main usage is to attach demons to variables.

Reimplemented in ortools.constraint_solver.pywrapcp.Pack, and ortools.constraint_solver.pywrapcp.TypeRegulationsConstraint.

Creates a Boolean variable representing the status of the constraint
(false = constraint is violated, true = constraint is satisfied). It
returns nullptr if the constraint does not support this API.
