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.

This method freezes the propagation queue.
It is useful when you need to apply multiple modifications at once.

It is called just after the post.

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

Calls Post and then Propagate to initialize the constraints.
This is usually done in the root node.

This method unfreezes the propagation queue.
All modifications that happened when the queue was frozen will be processed.

virtualinherited |
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.
