org.dbunit.database.search.ForeignKeyRelationshipEdge
Implementation of an edge representing a foreign key (FK) relationship between two tables.
The from node is the table which have the FK, while the to node is the table with the PK. In other words, the edge A->B means FK(A) = PK(B).
NOTE: only single-column PKs are supported at this moment @author Felipe Leme (dbunit@felipeal.net) @author Last changed by: $Author: gommma $ @version $Revision: 826 $ $Date: 2008-10-05 19:42:03 +0200 (dom, 05 ott 2008) $ @since 2.2 (Sep 9, 2005)
