Yea, I can see how that would work. You're just saying to put the "black box" in the ListView, right? Your DataProvider interface is a bit too simple (doesn't allow ordering, and EJB and Hibernate2 can't wrap an object in a model with only the object itself for reference), but I think it could work nicely with some fleshing out.
Returning an Iterator is very nice. If all you need to do is iterate, there's no reason to require a List. But because I'm implementing a List, there's no way to incorporate that. However, returning a list WILL use the cache, just not by default. You have to set useQueryCache to true. -Phil On 7/29/05, Igor Vaynberg <[EMAIL PROTECTED]> wrote: > The difference is my segment of code is the entire implementation, you are > implementing a few abstract methods on a surface of a black box. > > -Igor > > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] On Behalf Of > > Phil Kulak > > Sent: Friday, July 29, 2005 5:03 PM > > To: wicket-user@lists.sourceforge.net > > Subject: Re: [Wicket-user] lists > > > > On 7/29/05, Christian Essl <[EMAIL PROTECTED]> wrote: > > > Igor needs an eight-liner where you need a helper-class which is > > > complicated enough to put in an extra contribution-package. > > > OrderedPageList adds some indirection to get something > > which is less > > > efficient and more work to use. > > > > My "eight-liner" lookes almost exactly the same, (except for > > a few more lines of course): > > > > new QueryList() { > > protected List getItems(int start, int max, String orderBy) { > > session.createQuery("FROM Entity e" + orderBy) > > .setFirstResult(start).setMaxResults(max).list(); > > } > > > > protected int getCount() { > > return (Integer) session > > .createQuery("SELECT COUNT(*) FROM Entity e") > > .uniqueResult(); > > } > > } > > > > Or how about the same thing as a one-liner? > > > > new HibernateQueryList("FROM Entity e", dao); > > > > > Sure you have a List, with all those nice methods > > unfortunately many > > > are not supported and many are not recommended to use.
