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.GlobalVehicleBreaksConstraint, ortools.constraint_solver.pywrapcp.Pack, ortools.constraint_solver.pywrapcp.PyConstraint, and ortools.constraint_solver.pywrapcp.TypeRegulationsConstraint.

			vars )

Definition at line 2456 of file pywrapcp.py.

Post()

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.GlobalVehicleBreaksConstraint, ortools.constraint_solver.pywrapcp.Pack, and ortools.constraint_solver.pywrapcp.TypeRegulationsConstraint.

Definition at line 2377 of file pywrapcp.py.

)

Definition at line 2435 of file pywrapcp.py.

Var()

ortools.constraint_solver.pywrapcp.Constraint.Var

(

self

)

    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.
