Subject [jira] [Created] (TORQUE-161) Create filler methods for related objects
Date Fri, 24 Jun 2011 14:31:47 GMT
Create filler methods for related objects
-----------------------------------------

                 Key: TORQUE-161
                 URL: https://issues.apache.org/jira/browse/TORQUE-161
             Project: Torque
          Issue Type: New Feature
            Reporter: Thomas Fox
            Assignee: Thomas Fox


Currently, foreing relations can be filled either by lazy loading or by doSelectJoin... methods.
The former causes one db hit per object and the latter causes much unnecessary data to be
transferred if more than thwo related tables are filled.
Therefore, it should be possible to fill related objects by filler methods which take a Collection
of objects and load the objects related by a foreign key.
The fill should happen by generating new filler methods in the peer classes. In order not
to bloat the public API, the generation of these methods can be switched on by a generation
option. The default is that the filler methods are not created.
For example, if the Book table has a foreign key on the author table, the methods Book.Peer.fillAuthors(List<Book>)
and AuthorPeer.fillBooks(List<Author>) should be generated. They return the list of
related objects, so cascaded filling is easy.
