Interface DefinitionOrder

All Superinterfaces:

public interface DefinitionOrder
extends Iterable<aterm.ATermAppl>

A class to compute the definition order for concepts and tell if a concept is used in cyclic definition. The definition order is computed after the TBox preprocessing is applied so the definitions used for computing this order is not always same as asserted definitions. The notion of cyclic definition depends on the expressivity of the ontology. If there are no inverses a definition the concepts used inside restrictions are ignored.
