How would you recommend parameterizing table names or column names?
For instance, I have
public static final SRecordMeta <Parcels> meta = new
SRecordMeta<Parcels>(Parcels.class, "parcels");
to bind my Parcels class in Java to the "parcles" table in the database.
Now my clients want to switch back and forth between two different tables
without changing the source code and recompiling, so I'd like to change the
above line to:
public static final SRecordMeta <Parcels> meta = new
SRecordMeta<Parcels>(Parcels.class, ResourceUtil.getProperty(rbSD,
"sd.ParcelTableName", "parcels"));
The problem is that the meta object is a public static final, so it's
initializer is called before the resource bundle (rbSD) is read into
memory. And SRecordMeta.tableName is a private object with no set method.
I've asked this before, and the answer was "it's easy to do in SimpleORM"
but I haven't figured out that easy way to do it. Probably just some weird
mental block on my part. Can I just remove the final modifier and add a
static initialization routine?
