Interface GroupConstraint.AssignmentPairCheck

All Known Subinterfaces:

GroupConstraint.ConstraintTypeInterface

All Known Implementing Classes:

GroupConstraint.ConstraintType, GroupConstraint.ParametrizedConstraintType

Enclosing class:

GroupConstraint

public static interface GroupConstraint.AssignmentPairCheck

Group constraints that can be checked on pairs of classes (e.g., same room means any two classes are in the same room), only need to implement this interface. Unlike GroupConstraint.PairCheck, this check is also given current assignment.

Method Summary

Modifier and Type	Method and Description
boolean	isSatisfied(Assignment<Lecture,Placement> assignment, GroupConstraint gc, Placement plc1, Placement plc2) Check whether the constraint is satisfied for the given two assignments (required / preferred case)
boolean	isViolated(Assignment<Lecture,Placement> assignment, GroupConstraint gc, Placement plc1, Placement plc2) Check whether the constraint is satisfied for the given two assignments (prohibited / discouraged case)

Method Detail

isSatisfied

boolean isSatisfied(Assignment<Lecture,Placement> assignment,
                    GroupConstraint gc,
                    Placement plc1,
                    Placement plc2)

Check whether the constraint is satisfied for the given two assignments (required / preferred case)

Parameters:

assignment - current assignment

gc - Calling group constraint

plc1 - First placement

plc2 - Second placement

Returns:

true if constraint is satisfied

isViolated

boolean isViolated(Assignment<Lecture,Placement> assignment,
                   GroupConstraint gc,
                   Placement plc1,
                   Placement plc2)

Check whether the constraint is satisfied for the given two assignments (prohibited / discouraged case)

Parameters:

assignment - current assignment

gc - Calling group constraint

plc1 - First placement

plc2 - Second placement

Returns:

true if constraint is satisfied
