How to generating compareTo() method?

Using latest compilation from CVS of hibernate-tools3.0.1-beta1

I'm trying to generate the toCompare() method for my generated classes. I'm thinking of writing my own custom velocity template to do this.

I'm looking at the PojoEqualsHashcode.vm as en example. In that template, I see that a method called "needsEqualsHashCode()" is called on the pojo. Is there an equivalent somewhere for checking to see if it needs compareTo method? Or maybe I'm going down the wrong path on this one?

If anyone has a better way to do this, please let me know.

Thanks.

you are on the right path.

you will just need to define a meta attribute that ideintifies wether a compareto is needed.

if you add this then provide a patch and i'll integrate it.

This is a post from 2005. Does anyone know if this problem was solved?

If we create a compareTo method in one of our Hibernate domain model objects and then Use Hibernate Tools to regenerate the model, the compareTo is erased.

Is there any way to keep certain methods in an exisiting domain model object when using Hibernate Tools?

compareTo support was never contributed no.

I've always wanted to add support for jmerge into hibernatetools to allow retaining code between generations but have not happened - it would be *really* interesting though. hint-hint ;)

One way to add extra code via hbm.xml approach is to use meta attributes like:

Code:

Whatever is listed in class-code gets added to the end of the generated class.
