Exception Summary
UnassignedClassException UnassignedClassException is used when a method requires access to the Attribute designated as the class attribute in a set of Instances, but the Instances does not have any class attribute assigned (such as by setClassIndex()).
UnassignedDatasetException UnassignedDatasetException is used when a method of an Instance is called that requires access to the Instance structure, but that the Instance does not contain a reference to any Instances (as set by Instance.setDataset(), or when an Instance is added to a set of Instances)).
UnsupportedClassTypeException UnsupportedClassTypeException is used in situations where the throwing object is not able to accept Instances with the supplied structure, because the class Attribute is of the wrong type.
