[teneo] primary key in java code [message #86229] Wed, 13 June 2007 16:44 Go to next message

This has likely been answered, but I can't seem to find it.

I am unsure how to set a primary key using annotations in the java source --
not in an external xml file. I tried something like this

/**
* @model
*/
public interface A {
/**
* @model changeable="false"
*/
@Id
String getUniqueName();
}

Then I create a genmodel/ecore model from the code, generate the model, and
the uniquename property doesn't end up as the primary key. It's set to
changeable="false" because I am creating the value from other data, and that
gets stored find in the database.

Thanks,
Paul

Hi Paul,
Just for the id I would try the annotation id="true" in the java source. For other annotations: I
don't think that they will work, at least I don't think that eannotations can be specified in java
source. But maybe Ed can answer this question.

do you mean by using @model id="true", or something else?

It's working. I set @model id="true", and it becomes the primary key. It
did have a problem with my method name, though. I had declared the getter
as "getFQName()", and it complained that the impl class didn't have a get
method for property fQName. I changed it to "getFqname()", and it works
fine.

Thanks,
Paul

Martin,

Yes they can. :-) Like this:

* @model annotation="http://www.example.com foo='bar'"

So the syntax is {<source-URI> {<key>='<value>}*}* and you can use \ to
escape characters with special meaning.
