Moving methods to generated / changing interface +1 from me.

Get/SetByName, et. al.

IMHO, we need to have an interface that covers these.  A use case for this would
be common normalization or lookup functions.  E.g., a function with a record 
object
and column name as parameters that does something common to multiple table and 
columns, like scanning for profanity or normalizing case in across multiple 
tables that contains title and description fields.

Perhaps this could be based on the java LinkedHashMap object methods or the 
org.apache.commons.collections.OrderedMap interface?  With the key being 
the column name.  Then allow users the choice of simple persistent objects or 
collection based persistent objects (which is a superset of the simple objects).

I think you're right about getTableMap. That is Torque specific (but needed).  
If someone needs it inside a function using an interface parameter, they can 
always 
cast the object to get to it.

Subject: [jira] [Commented] (TORQUE-147) Database objects should not need to 
inherit from BaseObject

Thomas Fox commented on TORQUE-147:
-----------------------------------

I plan to impelemt this as follows:
- move the isNew and modified flags (incl getters and setters) from BaseObject 
to the generated base classes
- move the hashCode and equals methods from BaseObject to the generated base 
classes
- remove the class BaseObject from the runtime
- make all classes implement the org.apache.torque.om.Persistent interface
This makes all test cases green.

The following methods from BaseObject are not moved currently:
- get/setByName, get/setByPeerName, get/setByPosition: I would not define those 
as necessary for persistent objects. Maybe these methods can be moved to a 
different interface which is only implemented if the user choses to generate 
these methods ?
- getTableMap: Nots sure what to do with this method, if this were moved to the 
persistent interface it would make the interface rather Torque-specific. 
Currently it is not needed that the Persistent interface defines this method, 
and I'd rather leave this as is.

The following methods are already implemented/overridden:
- the save(...) methods which are defined in persistent are already generated
- the getters/setters for the primary key which are defined in BaseObject are 
overridden in the generated classes. However, to retain current catch clauses 
in the generated classes, I'd change the throws clauses in persistent from 
Exception to TorqueException, plus these methods need also be implemented 
(throwing UnsupportedOperationExceptions) for tables without primary key.

> Currently it is an error if database objects do not inherit from BaseObject. 
> This makes embedding of Torque objects in other frameworks very difficult, 
> because it does not allow to choose an own parent to inherit from.
> The minimum requirement would be that it is not required any more that 
> database objects inherit from BaseObject.
> Ideally BaseObject dies and the base objects inherit directly from 
> java.lang.object.
