Detailed Description
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).

Member Function Documentation
◆ accept()
|
inlineinherited |
Accepts the given visitor.
Reimplemented in Pack.
Definition at line 70 of file gen/java/com/google/ortools/constraintsolver/Constraint.java.
◆ baseName()
|
inlineinherited |
Returns a base name for automatic naming.
Reimplemented in BooleanVar.
Definition at line 115 of file PropagationBaseObject.java.
◆ delete()
|
inline |
Reimplemented from Constraint.
Definition at line 31 of file GlobalVehicleBreaksConstraint.java.
◆ enqueueDelayedDemon()
|
inlineinherited |
This method pushes the demon onto the propagation queue.
It will be processed directly if the queue is empty. It will be enqueued according to its priority otherwise.
Definition at line 72 of file PropagationBaseObject.java.
◆ enqueueVar()
|
inlineinherited |
Definition at line 76 of file PropagationBaseObject.java.
◆ freezeQueue()
|
inlineinherited |
This method freezes the propagation queue.
It is useful when you need to apply multiple modifications at once.
Definition at line 58 of file PropagationBaseObject.java.
◆ hasName()
|
inlineinherited |
Returns whether the object has been named or not.
Definition at line 108 of file PropagationBaseObject.java.
◆ initialPropagate()
|
inline |
This method performs the initial propagation of the constraint.
It is called just after the post.
Reimplemented from Constraint.
Definition at line 54 of file GlobalVehicleBreaksConstraint.java.
◆ isCastConstraint()
|
inlineinherited |
Is the constraint created by a cast from expression to integer variable?
Definition at line 77 of file gen/java/com/google/ortools/constraintsolver/Constraint.java.
◆ name()
|
inlineinherited |
Object naming.
Definition at line 97 of file PropagationBaseObject.java.
◆ post()
|
inline |
This method is called when the constraint is processed by the solver.
Its main usage is to attach demons to variables.
Reimplemented from Constraint.
Definition at line 50 of file GlobalVehicleBreaksConstraint.java.
◆ postAndPropagate()
|
inlineinherited |
Calls Post and then Propagate to initialize the constraints.
This is usually done in the root node.
Definition at line 63 of file gen/java/com/google/ortools/constraintsolver/Constraint.java.
◆ reset_action_on_fail()
|
inlineinherited |
This method clears the failure callback.
Definition at line 83 of file PropagationBaseObject.java.
◆ set_variable_to_clean_on_fail()
|
inlineinherited |
Shortcut for variable cleaner.
Definition at line 90 of file PropagationBaseObject.java.
◆ setName()
|
inlineinherited |
Definition at line 101 of file PropagationBaseObject.java.
◆ solver()
|
inlineinherited |
Definition at line 50 of file PropagationBaseObject.java.
◆ toString()
|
inline |
Reimplemented from Constraint.
Definition at line 46 of file GlobalVehicleBreaksConstraint.java.
◆ unfreezeQueue()
|
inlineinherited |
This method unfreezes the propagation queue.
All modifications that happened when the queue was frozen will be processed.
Definition at line 65 of file PropagationBaseObject.java.
◆ var()
|
inlineinherited |
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.
