# Klasse OMForeignKeyTransformer

java.lang.Object
org.apache.torque.templates.transformer.om.OMForeignKeyTransformer

public class OMForeignKeyTransformer extends Object
Sets the foreign tables for each of the foreign keys, and define variables, getters and setters for the complexObjectModel. So the source elements are (attributes not shown) foreign-key reference reference ... and the result is foreign-key reference local-column column foreign-column column reference local-column column foreign-column column ... local-field (properties for the field on the local table's database object referencing the foreign database object) foreign-field (properties for the field on the foreign table's database object referencing the local database objects) table (the foreign referenced table) On running this transformer, the javaName Attribute on the columns must be set properly.
