SetLexicographicOrdering
public SetLexicographicOrdering(SetVar v0,
SetVar v1)
toString
public String toString()
- Overrides:
toString
in class AbstractSConstraint<SetVar>
pretty
public String pretty()
- Description copied from interface:
IPretty
- pretty printing of the object. This String is not constant and may depend on the context.
- Specified by:
pretty
in interface IPretty
- Overrides:
pretty
in class AbstractSConstraint<SetVar>
- Returns:
- a readable string representation of the object
propagate
public void propagate()
throws ContradictionException
- Description copied from class:
Propagator
- Propagation:
Propagating the constraint until local consistency is reached.
- Specified by:
propagate
in class Propagator
- Throws:
ContradictionException
- contradiction exception
isConsistent
public boolean isConsistent()
- Description copied from class:
Propagator
- tests if the constraint is consistent with respect to the current state of domains
- Specified by:
isConsistent
in class Propagator
- Returns:
- wether the constraint is consistent
isSatisfied
public boolean isSatisfied()
- Description copied from interface:
SConstraint
- Semantic:
Testing if the constraint is satisfied.
Note that all variables involved in the constraint must be
instantiated when this method is called.
- Returns:
- true if the constraint is satisfied
