Hibernate version: 3


Hi !

I am trying to creat new id generator and I have some problems.

I need generator that will look at id, and if id is set, and more than zero then it will use it, if id is not set or/and less or equal to 0 , then it will return next free id. So this generator will be Assign/Increment.

Method generate() is quite straightforward, but I am little confused with configure() method.

Can somebody point to any documentation on how to do this? Or if there are any samples?

Thanks for all help in advance.

You know that Hibernate is open source?

As Christian hinted, take a look at the id generators themselves, esp. the ones you want to fall back on if the id is not already assigned.

Having looked at doing something similar myself, I must remind you to set the unsaved-value parameter of the id fields to something suitable (in my case, I ended up using 'undefined'). Otherwise, when it comes to cascading a save or update, the update option would always be taken.

Hi guys !

Thanks for info. I know that software is Open Source (and I know definition of Open Source).

I have two classes to which I will fall back, first is Asssigned and second is IncrementGenerator.

Problem is with second method (implemented from Configurable). I don't know exactly when it's called. If it's called before generate, then I have a problem, but if not then everything will be ok.

I will send message here how I am proceeding...

Hi !

It's been quite some time since my last post. I have created this id generator and called it AssignedIncrementGenerator. I have been using it for few years now and it seems to work ok.

I would like to contribute it to hibernate source code, since there are probably some users who would find it's functionality helpful.
How can I do that?
