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

 Note that the foreign keys in the foreign-keys and referencing-foreign-keys
 are the original elements, not just copies.
