public interface VariableSolution

extends java.lang.Cloneable

Interface implemented by all variable solutions

Method Summary

java.lang.Object	clone()
CspVariable	getVariable() Returns variable solution is based upon
boolean	isBound() Returns true if variable is bound in solution
void	restore() Restores (certain) recorded information to the associated variable.
void	store() Causes variable solution to capture certain information about it's variable and store it locally so that it can be restored later.

Method Detail

getVariable

public CspVariable getVariable()

Returns variable solution is based upon

isBound

public boolean isBound()

Returns true if variable is bound in solution

store

public void store()

Causes variable solution to capture certain information about it's variable and store it locally so that it can be restored later. History is not kept: calling this method overwrites any previous information captured from previous calls to this method.

restore

public void restore()
             throws PropagationFailureException

Restores (certain) recorded information to the associated variable. This is the information stored when the store() was most recently called.

Throws:

PropagationFailureException

clone

public java.lang.Object clone()
