public class StudentOverlapConflict
extends StudentConflict

Student overlapping conflicts. This criterion counts student overlapping conflicts between classes. An overlapping conflict occurs when two classes that are attended by the same student (or students) are overlapping in time (i.e., TimeLocation.hasIntersection(TimeLocation) is true).
