All Implemented Interfaces:

net.sf.tweety.commons.Formula, net.sf.tweety.logics.commons.syntax.interfaces.ClassicalFormula, net.sf.tweety.logics.commons.syntax.interfaces.Conjunctable, net.sf.tweety.logics.commons.syntax.interfaces.Disjunctable, net.sf.tweety.logics.commons.syntax.interfaces.Invertable, net.sf.tweety.logics.commons.syntax.interfaces.ProbabilityAware, net.sf.tweety.logics.commons.syntax.interfaces.SimpleLogicalFormula

public class AtomicRole
extends ComplexConcept

This class models a role in description logics.
Note: Role assertions like (a,b):r ("the Individuals a,b are in the extension of the role r") are modeled with a different class: ConceptAssertion.
