> Support specification of exact class in SingleFieldIdentity
> -----------------------------------------------------------

>
> When calling PersistenceManager.getObjectById() with a SingleFieldIdentity,
> there seems to be no way of avoiding the following
> (if the implementation decides to do so):
> "It is an implementation decision whether to access the data store, if
> required to determine the exact class. This will be the case of inheritance,
> where multiple <code>PersistenceCapable</code> classes share the same
> ObjectId class."
> Now when I know for sure that the targetClassName of the given
> SingleFieldIdentity already denotes the correct class for the given id, how
> can I avoid that additional roundtrip to the database for finding the exact
> class?
> It would be useful to have a way of specifying a SingleFieldIdentity to be
> for the exact class specified. This could be done by addition of methods
> void setExact(boolean flag);
> boolean getExact();
> to SingleFieldIdentity
