Method Detail

getSize

public int getSize()

Returns size of domain

setDomain

public void setDomain(jopt.csp.util.NumSet s)
               throws jopt.csp.variable.PropagationFailureException

Attempts to reduce a domain by restricting it to a set of values

Throws:

jopt.csp.variable.PropagationFailureException - If domain is empty

removeDomain

public void removeDomain(jopt.csp.util.NumSet vals)
                  throws jopt.csp.variable.PropagationFailureException

Attempts to reduce a domain by removing a set of values

Throws:

jopt.csp.variable.PropagationFailureException - If domain is empty

values

public jopt.csp.util.NumberIterator values()

Returns iterator of values in node's domain

deltaValues

public jopt.csp.util.NumberIterator deltaValues()

Returns iterator for the node's delta set containing values that have been removed from the domain since clearDelta was last run.

toSet

public jopt.csp.util.NumSet toSet()

Returns set of Numbers and NumIntervals representing domain

getDeltaSet

public jopt.csp.util.NumSet getDeltaSet()

Returns the delta set containing values that have been removed from the domain since clearDelta was last run.
