Please keep this on-list.
I haven't actually tried it and don't know what you mean by "overhead", but the
core idea would be sth like:
public Session() {
EOModelGroup modelGroup = new EOModelGroup();
EOModel model = modelGroup.addModelWithPath("/some/where"); // model should
be in a subfolder of "Resources" so it won't get loaded
adjustConnectionDict(model);
EOAdaptor adaptor = EOAdaptor.adaptorWithModel(model);
EODatabaseContext dbc = new EODatabaseContext(adaptor);
EOObjectStoreCoordinator osc = new EOObjectStoreCoordinator();
osc.addCooperatingObjectStore(dbc);
EOEditingContext ec = new EOEditingContext(osc);
setDefaultEditingContext(ec);
}
This probably won't even compile, but should get you started. All other ECs
must be created as
new EOEditingContext(session().defaultEditingContext().parentObjectStore())
or from a thread-local.
Cheers, Anjo
