BinaryConstraintWithContext() 
Modifier and Type  Method and Description 

void 
assigned(Assignment<V,T> assignment,
long iteration,
T value)
Given value is to be assigned to its variable.

AssignmentContextReference<V,T,C> 
getAssignmentContextReference()
Returns an assignment context reference

AssignmentContext[] 
getContext()
An array of
CanHoldContext.sMaxSize assignment contexts 
C 
getContext(Assignment<V,T> assignment)
Returns an assignment context associated with this constraint.

void 
setAssignmentContextReference(AssignmentContextReference<V,T,C> reference)
Store an assignment context reference that was given for the class by the
Model.createReference(HasAssignmentContext) . 
void 
setModel(Model<V,T> model)
Sets the model which the constraint belongs to

void 
unassigned(Assignment<V,T> assignment,
long iteration,
T value)
Given value is unassigned from its variable.
