Method Detail

constraintBeforeAssigned

void constraintBeforeAssigned(long iteration,
                              Constraint<?,T> constraint,
                              T assigned,
                              Set<T> unassigned)
Called by the constraint, before a value is assigned to its variable.

Parameters:
iteration - current iteration
constraint - source constraint
assigned - value which will be assigned to its variable ( Value.variable())
unassigned - set of conflicting values which will be unassigned by the constraint before it assigns the given value

constraintAfterAssigned

void constraintAfterAssigned(long iteration,
                             Constraint<?,T> constraint,
                             T assigned,
                             Set<T> unassigned)
Called by the constraint, after a value is assigned to its variable.

Parameters:
iteration - current iteration
constraint - source constraint
assigned - value which was assigned to its variable ( Value.variable())
unassigned - set of conflicting values which were unassigned by the constraint before it assigned the given value
