public class Ontology
extends java.lang.Object

Very simple ontology class. Two static ontologies are available: ATTRIBUTE_BLOCK_TYPE and ATTRIBUTE_VALUE_TYPE. It provides a single method boolean isA(int sub, int super) which does what isA-methods are usually expected to do. Legal parameters are the constants.
