Examples of helma.objectmodel.db.Relation

helma.objectmodel.db.Relation
This describes how a property of a persistent Object is stored in a relational database table. This can be either a scalar property (string, date, number etc.) or a reference to one or more other objects.

    private TransientProperty getProperty(String propname) {
        TransientProperty prop = (propMap == null) ? null : (TransientProperty) propMap.get(propname);


        // check if we have to create a virtual node
        if ((prop == null) && (dbmap != null)) {
            Relation rel = dbmap.getPropertyRelation(propname);


            if ((rel != null) && rel.isVirtual()) {
                prop = makeVirtualNode(propname, rel);
            }
        }


        return prop;

        // if this is a HopObject, check if the property is defined

            if (dbm != null) {
