- java.lang.Object
- - org.apache.torque.templates.transformer.om.OMForeignKeyColumnTransformer

-     public class OMForeignKeyColumnTransformer
      extends Object

  Sets the referenced and referencing columns for the column. These references are defined by foreign key definitions. The structure before transformation is: database table column column ... foreign-key reference foreign-key reference reference ... ... table table ... The structure after transformation is database table column referenced-column (a foreign key exists containing the current column as local reference) column (the foreign reference of the said foreign key) foreign-key (the foreign key defining the relation) referencing-column (a foreign key exists containing the current column as foreign reference) column (the local reference of the said foreign key) foreign-key (the foreign key defining the relation) referencing-column column foreign-key ... column ... foreign-key reference foreign-key reference reference ... ... table table ... Note that the foreign keys in the foreign-keys and referencing-foreign-keys are the original elements, not just copies.
