EMF Code Generation: Separating generic classes according to schema structure [message #654898] Thu, 17 February 2011 14:23 Go to next message

I am working on a project consisting of several XSD files... lets call them
the specific shema files. They all include a reference to another XSD
containing base (generic) elements definitions. When I create my genmodel
and code generate, all the classes end-up in the EMF project related to the
specific schema. I just dont want to end-up with several duplications of the
same classes.

I could generate the classes from the XSD which includes the generic
elements and then delete them from each other projects however there must be
a faster cleaner way?

Regards,

Yves

You should be able to generate the base model separately first and
reference it from the other models that reuse it.

In the final page of the wizard, you ensure that you reuse the
GenPackage for the already-generated base model.

Thanks for the info Ed. There seems to be a problem with this approach, the
Elipse documentation for the library example states the following:

<<In general, more than one package may be produced from a single schema if
it includes other schemas that declare different target namespaces. Select
the package for which you want to generate an EMF model -- in this case, the
only package, "org.eclipse.example.library". Click the "Finish" button.>>

However in my case, the same namespace is used in both the generic schema
and the specific ones. From the wizard, when I try to check the "Referenced
generator models" I added (the one containing the generic classes), the root
package at the top dissapers. It looks like I have to choose one or the
other... and if there is no package to generate the "finish" button is
greyed-out of course.

I searched inside the genmodel properties for something that would look like
a reference to a different genmodel however I could not find it.

Not sure what to do next.

Yves

There's only one package then and you can't split it.

You can only do that if you have multiple packages with different
namespaces.
