Pete:
I understand and support the concern re. mixing in the Parameter
object. Personally I would prefer Map over Query. Here is my
understanding of what the interface would look like (all method
included) based on quasi "consensus" at this stage + your
suggested replacement of Parameters with Map.
interface ServiceManager
{
Object lookup( final String role );
Object lookup( final String role, final Map attributes );
boolean hasObject( final String role );
void release( Object object );
}
Is this ok with everyone?
Steve.
