Not without bigger changes in the AbstractBaseManager. I will have a
look at this. I guess the real fun starts if I want to cache the whole
collection of books at once (using MethodResultCache for example, not to
speak of invalidation).
Replying to myself is fun...
Well, I finally came up with an attempt for a solution. It was less work
than I expected, but I guess we are only halfway through. It passes the
runtime test, however.
It looks like this:
---8<---
public Author getAuthor(Connection connection)
throws TorqueException
{
if (aAuthor == null && (this.authorId != 0))
{
aAuthor =
AuthorManager.getCachedInstance(SimpleKey.keyFor(this.authorId));
if (aAuthor == null)
{
aAuthor =
AuthorPeer.retrieveByPK(SimpleKey.keyFor(this.authorId), connection);
AuthorManager.putInstance(aAuthor);
}
}
return aAuthor;
}
---8<---
While I was at it I corrected a few problems PMD complained about, but
there is still room for improvement... :-)
Any comments are welcome.
Bye, Thomas.
