Loading nodes in collection on demand

Hi,

Realized that when calling LocalDatabase.objectForName() on a FullTreeMap
object which has been created in the database, the readObject() method of
the nodes the collection contains is being called. Based on that, it seems
to me that all of the nodes in the collection gets loaded into the memory.
The numbers of the nodes in the collection could be quite large and loading
them would require lots of RAM.
Should the node in the collection be loaded on demand?

What is the different between adding database object (extends OzoneObject)
and adding serializable object (extends Serializable) into ozone collection,
e.g. FullTreeMap?
Thanks,
