RavenDB Workshops - Deep dive into practical use of Document Data Modeling

Linq for NHibernate Updates

time to read 1 min | 198 words

I got a couple of great patches yesterday and today, Bobby Diaz sent a patch to add support for Count() and DataContext like behavior. Jon Stelly went and cleaned up my code, turning it from a sleep-deprived hack into a respectable project. You can see his full list here. Thanks to their efforts, this now works:

(from user in orm.Users select user).Count();

I changed the implementation of NHibernteLinqQuery to use the visitor pattern, which is the natural way that I think about walking through an AST. It is still very primitive one, but it does the job that we need right now.

The new code is in the repository:

svn co https://rhino-tools.svn.sourceforge.net/svnroot/rhino-tools/experiments/NHibernate.Linq/

Bobby and Jon, thanks again. Everyone else, you are invited to the party as well.
