Add lazy attribute to class tag
-------------------------------
Key: HIB-72
URL: http://jira.andromda.org/browse/HIB-72
Project: Hibernate Cartridge
Type: New Feature
Versions: 3.0RC1
Reporter: Peter Wyngaard
Assigned to: Martin West
It would be nice to be able to set the 'lazy' attribute of the Hibernate
'class' tag to true.
I have a many-to-one relationship from a "Document" entity to a "ClobStore"
entity which stores multiple Clob fields for a given document. This was
encouraged by the DBA on the project so that he could "do the right thing" in
the database.
Anyway, there are many scenarios where I don't want the Clobs to be loaded when
I load a Document. So, I need two things:
1. Turn off outer join fetching on queries
2. Enable lazy loading of the Clobs
#1 was easy to set up using the @andromda.hibernate.outerjoin tagged value on
the association ends.
The only way I know of to implement #2, for a many-to-one relationship, is by
setting the 'lazy' attribute to 'true' on the 'class' tag in ClobStore.hbm.xml.
Problem is, can't do that in AndroMDA (yet)!
Sound like a good idea to add an @andromda.hibernate.lazy tagged value to
Entities?
Thanks,
Peter
