Method Summary |
void |
awake()
Propagation:
Propagating the constraint for the very first time until local
consistency is reached. |
void |
awakeOnBounds(int varIndex)
|
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 x)
Default propagation on one value removal: propagation on domain revision. |
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 idx)
Default propagation on improved upper bound: propagation on domain revision. |
int |
getFilteredEventMask(int idx)
|
String |
pretty()
pretty printing of the object. |
void |
propagate()
Propagation:
Propagating the constraint until local consistency is reached. |
void |
reviseV0()

void |
reviseV1()
