Constructor Summary

CspLargeConstraint(IntDomainVar[] vs, LargeRelation relation)

Method Summary

void	awakeOnBounds(int varIndex)
void	awakeOnInst(int idx) Default propagation on instantiation: full constraint re-propagation.
void	awakeOnRemovals(int idx, IntIterator 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.
java.lang.Object	clone() returns a copy of the constraint.
LargeRelation	getRelation()
java.lang.Boolean	isEntailed() Checks whether the constraint is definitely satisfied, no matter what further restrictions occur to the domain of its variables.
boolean	isSatisfied() Semantic: Testing if the constraint is satisfied.
AbstractConstraint	opposite() computes the constraint modelling the counter-opposite condition of this
void	propagate() Propagates the constraint awake events.

Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Description copied from interface: Constraint

returns a copy of the constraint. This copy is a new object, may be a recursive copy in case of composite constraints. The original and the copy share the same variables & plugins

Specified by:

clone in interface Constraint

Overrides:

clone in class AbstractLargeIntConstraint

Returns:

Throws:

java.lang.CloneNotSupportedException

getRelation

public LargeRelation getRelation()

propagate

public void propagate()
               throws ContradictionException

Description copied from class: AbstractLargeIntConstraint

Propagates the constraint awake events.

Specified by:

propagate in interface Propagator

Overrides:

propagate in class AbstractLargeIntConstraint

Throws:

ContradictionException

awakeOnRemovals

public void awakeOnRemovals(int idx,
                            IntIterator deltaDomain)
                     throws ContradictionException

Description copied from class: AbstractIntConstraint

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.

Specified by:

awakeOnRemovals in interface IntConstraint

Overrides:

awakeOnRemovals in class AbstractIntConstraint

Throws:

ContradictionException

awakeOnBounds

public void awakeOnBounds(int varIndex)
                   throws ContradictionException

Specified by:

awakeOnBounds in interface IntConstraint

Overrides:

awakeOnBounds in class AbstractIntConstraint

Throws:

ContradictionException

awakeOnInst

public void awakeOnInst(int idx)
                 throws ContradictionException

Description copied from class: AbstractIntConstraint

Default propagation on instantiation: full constraint re-propagation.

Specified by:

awakeOnInst in interface IntVarEventListener

Overrides:

awakeOnInst in class AbstractIntConstraint

Throws:

ContradictionException

isSatisfied

public boolean isSatisfied()

Description copied from interface: Constraint

Semantic: Testing if the constraint is satisfied. Note that all variables involved in the constraint must be instantiated when this method is called.

opposite

public AbstractConstraint opposite()

Description copied from interface: Constraint

computes the constraint modelling the counter-opposite condition of this

Specified by:

opposite in interface Constraint

Overrides:

opposite in class AbstractConstraint

Returns:

a new constraint (modelling the opposite condition)

isEntailed

public java.lang.Boolean isEntailed()

Description copied from interface: Propagator

Checks whether the constraint is definitely satisfied, no matter what further restrictions occur to the domain of its variables.

Specified by:

isEntailed in interface Propagator

Overrides:

isEntailed in class AbstractConstraint
