public final class SpecialAttribute
extends SymbolAttribute

Represents special values in queries or cases. The semantics can be defined separately. There is one SpecialValueAttribute for each attribute description that wraps one SpecialValue object. This assures consistency since we expect that each value occurring in query or case knows its attribute description and is of type SimpleAttribute. Objects of this class are maintained by ranges defined in AttributeDesc objects.
