Class Method Details

.autoload_object(rid) ⇒ Object

Example:

ActiveOrient::Model.autoload_object "#00:00"

either retrieves the object from the rid_store or loads it from the DB.

The rid_store is updated!

To_do: fetch for version in the db and load the object if a change is detected

Note: This function is not in ModelClass since it needs to use @@rid_store
