Class EDOALRelation

java.lang.Object
  fr.inrialpes.exmo.align.impl.edoal.EDOALRelation

All Implemented Interfaces:

Relation, Visitable

public class EDOALRelation
extends Object
implements Relation

Represents an ontology alignment relation. In fact, for the EDOAL Mapping language, this encodes directions but should be rewritten in order to achive a better implementation I feel this is not used anymore
