typedef int Gecode::ModEventDelta |
Modification event deltas.
Modification event deltas are used by propagators. A propagator stores a modification event for each variable type. They can be accessed through a variable or a view from a given propagator. They can be constructed from a given modevent by a variable or view.
The actual cost values that are used.
Actor properties.
Enumerator | |
---|---|
AP_DISPOSE |
Actor must always be disposed. Normally, a propagator will not be disposed if its home space is deleted. However, if an actor uses external resources, this property can be used to make sure that the actor will always be disposed. |
AP_WEAKLY |
Propagator is only weakly monotonic, that is, the propagator is only monotonic on assignments. |
