This provides the implementation of {@link DBCachedObjectStore#asMap()}

<p>
This implements a map from object id (long) to object. Objects cannot be added directly to this
map, e.g., {@link #put(Long, DBAnnotatedObject)} is not supported. Instead use
{@link DBCachedObjectStore#create(long)}.

@param <T> the type of objects in the store
