Hi, I am using emft to gen some codes from a ecore model.
My ecore model has a EPackage and more than one eClass, I want my templates
to transform each eClass.
That is, I have a templte list.emf
I have an ecore model which contains classes: Ant, Cat, Rat
I want to get results
list_ant.jsp
list_cat.jsp
list_rat.jsp
Also since the class name can change anytime, and more classes can be added
in.

Thanks in advance!

Lipan,

Have you looked at the JET2 examples or looked at the JET articles on
the EMF documentation page?

Some useful links:

Thanks for your response

I have read this pages, and have done some emft templates.
But I don't think they can answer my question.

Maybe it is my mistake. But follwing the document, I cann't get what I want
I have a package, it has classes Ant, Cat, Rat
Then I have a tempalte list.emf
What I want is three files,
list_ant.jsp which is based on Ant's properties
and
list_cat.jsp which is based on Cat's properties

This is my list.emf:

<html>
<body>

<c:iterate select="/contents/eClassifiers" var="currNode">
Name = <c:get select="$currNode/@name" />
</c:iterate>

</body>
</html>

yes it produce a file, which list all these classifiers, but I only want
three files, each list one classifiler

I thought <ws:file/> can help me, but it can only process the whole ecore
module(which list all 3 classifers)
I think it may be useful to write something like
<c:iterate select="/contents/eClassifiers" var="currNode">
<ws:file template="list.emf" processnode="$currNode/@name" />
</c:iterate>

but ws:file can't work this way.

Lipan:

Your second instinct is nearly right:

> <c:iterate select="/contents/eClassifiers" var="currNode">
> <ws:file template="list.emf" processnode="$currNode/@name" />
> </c:iterate>

But, JET doesn't do parameter passing the way you are expecting (or for that
matter, the way I'd like it to). The variable 'currNode' is global, so you'd
do the following:

In templates/main.jet:

<c:iterate select="/contents/eClassifiers" var="currNode">
<ws:file template="templates/list.emf.jet"
path="some-project/list_{$currNode/@name}.jsp"/>
</c:iterate>

Note the XPath expression in braces { } embedded in the path attribute. This
can be enhanced using functions to make the name lowercase:

<ws:file template="templates/list.emf.jet"
path="some-project/list_{lower-case($currNode/@name)}.jsp"/ >

Finally, in templates/list.emf.jet, you would do whatever it is you want:

This is the content for: <c:get select="$currNode/@name"/>
....
