Method Summary

void	constraintAfterAssigned(long iteration, Constraint constraint, Value assigned, Set unassigned) Called by the constraint, after a value is assigned to its variable.
void	constraintBeforeAssigned(long iteration, Constraint constraint, Value assigned, Set unassigned) Called by the constraint, before a value is assigned to its variable.

Method Detail

constraintBeforeAssigned

void constraintBeforeAssigned(long iteration,
                              Constraint constraint,
                              Value assigned,
                              Set 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 constraint,
                             Value assigned,
                             Set 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
