public class GlobalVehicleBreaksConstraint
extends Constraint

GlobalVehicleBreaksConstraint ensures breaks constraints are enforced on
all vehicles in the dimension passed to its constructor.
It is intended to be used for dimensions representing time.
A break constraint ensures break intervals fit on the route of a vehicle.
For a given vehicle, it forces break intervals to be disjoint from visit
intervals, where visit intervals start at CumulVar(node) and last for
node_visit_transit[node]. Moreover, it ensures that there is enough time
between two consecutive nodes of a route to do transit and vehicle breaks,
i.e. if Next(nodeA) = nodeB, CumulVar(nodeA) = tA and CumulVar(nodeB) = tB,
then SlackVar(nodeA) >= sum_{breaks [tA, tB)} duration(break).

finalize

protected void finalize()

Overrides:

finalize in class Constraint

delete

public void delete()

Overrides:

delete in class Constraint

toString

public java.lang.String toString()

Overrides:

toString in class Constraint

post

public void post()

Description copied from class: Constraint

This method is called when the constraint is processed by the
solver. Its main usage is to attach demons to variables.

Overrides:

post in class Constraint

initialPropagate

public void initialPropagate()

Description copied from class: Constraint

This method performs the initial propagation of the
constraint. It is called just after the post.

Overrides:

initialPropagate in class Constraint
