Method Summary | |
---|---|
void |
awake()
Default initial propagation: full constraint re-propagation. |
void |
awakeOnBounds(int varIndex)
|
void |
awakeOnInf(int varIdx)
Default propagation on improved lower bound: propagation on domain revision. |
void |
awakeOnInst(int idx)
Default propagation on instantiation: full constraint re-propagation. |
void |
awakeOnRemovals(int idx,
DisposableIntIterator deltaDomain)
The default implementation of propagation when a variable has been modified consists in iterating all values that have been removed (the delta domain) and propagate them one after another, incrementally. |
void |
awakeOnSup(int varIdx)
Default propagation on improved upper bound: propagation on domain revision. |
int |
getFilteredEventMask(int idx)
|
Boolean |
isEntailed()
Indicates if the constraint is entailed, from now on will be always satisfied |
boolean |
isSatisfied(int[] tuple)
TEMPORARY: if not overriden by the constraint, throws an error to avoid bug using reified constraints in constraints that have not been changed to fulfill this api yet ! |
AbstractSConstraint<IntDomainVar> |
opposite(Solver solver)
Get the opposite constraint |
void |
propagate()
Propagation: Propagating the constraint until local consistency is reached. |
