[1.1 Proposal] Introduce an IdentityFactory
Hi all,
I propose to introduce an IdentityFactory class by a service method in
PB (think some users made a similar proposal in the past):
PB.serviceIdentityFactory
IdentityFactory will simplify the creation of Identity objects and will
make find by primary key much easier.
Currently user have to create a Identity object on its own and do
(assume we use a single PK per class)
Object[] pkValueArray = new Object[]{new Integer(4711)};
Class topLevelClass = broker.getTopLevelClass(realClass);
Identity oid = new Identity(realClass, topLevelClass, pkValueArray)
Object result = broker.getObjectByIdentity(Identity oid)
The creation of the Identity object is a mess!
With the new service class same example look like
Identity oid = broker.serviceIdentityFactory.buildIdentity(realClass,
new Integer(4711));
Object result = broker.getObjectByIdentity(Identity oid)
Any comments?
regards,
Armin
public interface IdentityFactory
{
Identity buildIdentity(Object obj);
Identity buildIdentity(ClassDescriptor cld, Object obj);
Identity buildIdentity(Class realClass, Class topLevelClass,
String[] pkFieldName, Object[] pkValues);
Identity buildIdentity(Class realClass, String[] fieldName,
Object[] pkValues);
Identity buildIdentity(Class realClass, Object pkValue);
}

Because we are focused on development of OJB, not usage ;-)

Hi Armin,
+1
Of course this is a much needed feature. why did we never think of it
before?
I'd also love to have a replacement for
Identity oid = new Identity(obj,broker);
maybe something like:
Identity oid = broker.serviceIdentityFactory.buildIdentity(obj);
This would help users working with example objects.
have a nice weekend,
Thomas
