Bag class mapping (Collection or List)

freestyle65 · **Joined:** Thu Apr 06, 2006 11:56 am **Posts:** 2

Hello,

with the last releases of tools, hbm2java generates a java.util.Collection for bags as default, instead of java.util.List.

How to change this behaviour and force it to generate bags as List ? I need this for backward compatibility with previous source code.

Thanks in advance,
David

Edit the code generation script (Velocity or Freemarker depending on the version) to output the format your after.

it was changed because Collection is actually the more correct way of representing it, but no worries I provided a work around:

<bag ...>
<meta attribute="property-type">java.util.List</meta>
....
</bag>

And that can be used generally, but mostly intended to remedy this one.

Hello,

I am facing the same problem as above. Adding
<meta attribute="property-type">java.util.List</meta>
is not ra really good solution, because it does not consider generics. I don't want

Code:

List ...

, but

Code:

List<MyClass> ...

.

So I changed the meta-tag to

Code:

<meta attribute="property-type">java.util.List<${property.getValue().getElement().getReferencedEntityName()}></meta>

Now I get nice declarations like "List<Y> x;" However no initialization code is generated anymore.

Is it possible to create declarations like

Code:

List<Y> x = new Vector<Y>();

and what needs to be changed to achieve this?

Thanks for your help

Wolfgang

we handle generics fine for everything else ;)

Please put it in jira with a reference to this.

We probably should just allow users to set the default for bags.

is this code in the hibernate source or the tools source? I need it to implement List with generics also.

edit: I couldn't find a jira issue related to this so I made one here http://opensource.atlassian.com/project ... se/HBX-666

they are in the hibernate-tools.jar (and hence in the hibernate tools src, but you can just take them from the jar)

bahh, I can't find it in the source code, any chance you could point me to the file that handles this?

e.g. hibernate-tools.jar/dao/daohome.ftl or hibernate-tools.jar/pojo/*.ftl
