Method Summary |
void |
awake()
Propagation:
Propagating the constraint for the very first time until local
consistency is reached. |
void |
awakeOnInf(int idx)
Default propagation on improved lower bound: propagation on domain revision. |
void |
awakeOnInst(int idx)
Default propagation on instantiation: full constraint re-propagation. |
void |
awakeOnRem(int idx,
int val)
Default propagation on one value removal: propagation on domain revision. |
void |
awakeOnRemovals(int idx,
DisposableIntIterator it)
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 idx)
Default propagation on improved upper bound: propagation on domain revision. |
protected IStateInt |
getTypeNeed(int nbDays,
int shiftType)

Propagation:
