All Implemented Interfaces:

IExplainable, TaxonomyNode

Direct Known Subclasses:

SpecialAttribute

public class SymbolAttribute
extends SimpleAttribute
implements TaxonomyNode

Represents values of symbol attribute descriptions (for example: color could have green, blue, red, ... as SymbolAttribute objects). A symbol attribute depends on a description (so if you have two attribute descriptions for color there would be two SymbolAttribute objects for green). However, if green (for a fixed description) appears in several cases, the corresponding SymbolAttribute object is referenced. SymbolAttribut objects are maintained by SymbolRange
