Mmh, I understand that, so if I have an Interface Issue and a composite IssueEntity I would try to get an instance via
Issue issue = uow.newEntity(Issue.class); and qi4j wil figure our that there is an IssueEntity that extends Issue? But if there isn't such a construction and I just do Double latittude = uow.newEntity(Double.class); what happens? Could we give back a reasonable Exception that explains that you have to have an Entity extended somewhere in order to use this? /peter On Mon, May 5, 2008 at 6:03 PM, Rickard Öberg <[EMAIL PROTECTED]> wrote: > Peter Neubauer wrote: > > Hi there, > > now that I got a bit further, it seems the UoW API is a bit blury on > > <T> T newEntity( Class<T> compositeType ); > > > > <T> T newEntity( String identity, Class<T> compositeType ); > > > > <T> CompositeBuilder<T> newEntityBuilder( Class<T> compositeType ); > > > > <T> CompositeBuilder<T> newEntityBuilder( String identity, > > Class<T> compositeType ); > > > > Shouldn't the newEntity methods only take instances of > org.qi4j.entity.Entity? > > As Niclas indicated these methods map the given types to actual > Composite types.
