Subject [jira] Commented: (TORQUE-75) Map XML column informations to the generated Objects
Date Fri, 15 Dec 2006 14:23:27 GMT
    [ http://issues.apache.org/jira/browse/TORQUE-75?page=comments#action_12458806 ] 
CG Monroe commented on TORQUE-75:

This is all available from the associated ColumnMap object.  All you need to do is use:

   ColumnMap cMap = rec.getTableMap().getColumn( RecPeer.COL );

   ColumnMap cMap = RecPeer.getTableMap().getColumn( RecPeer.COL );

cMap has methods to get XML schema information like getDescription(), isNotNull(), getSize(),

This is all metadata that only need to be stored once and not in each generated object class.

Note:  Some of this was available in V3.2... but 3.3-RC1 has major rewrite of this.  See Torque-22

> There is a small leakage of informations between XML definition and the generated Object.

> For example if you define a column as required="true" it would be good to get this information
in the object. So there could be a method like isMandatory(COLUMNNAME). One application for
this could be generic analyzing of objects before saving to avoid SQL exceptions.
> Other informations would be size, scale and description for example.
> Of course we could retrieve this informations from the database but this means that we
have to communicate with the database and there could be database specific inconsistency.
