Access localPart of QName [message #870005] Sat, 05 May 2012 16:03 Go to next message

Hi,

as I could not add comments in the old M2M forum, I repeat the question in this new forum:

I want to access the local part of a qName in Qvto. In ATL I did this:

name <- s.qName.getLocalPart()


in QVT:

name := self.qName.???


Any ideas? getLocalPart seems not to work.


Edit:

In the WSDL.ecore there is qName of type javax.xml.namespace.QName. So obviously it is not possible to call the according java methods in Qvt?

Regards

Tex

Hi

Have you tried qName.localPart ??? If its a property then you just use
the name. If it was a helper function then you will need to provide it.

Hi Ed,

thanks for your answer. Yes, I tried it too, does not work.

docs.oracle.com/javase/1.5.0/docs/api/javax/xml/namespace/QName.html

QName has a method "getLocalPart()". Maybe the problem is, that QVTo does not recognize that qName field is of type javax.xml.namespace.QName or is not able to work on this java implementation.

Regards,

Tex

Hi

You looking at the Javadoc that describes a Java API.

When you use modeling tools you should look at the models directly. So
you probably want XMLType.ecore where you will finf that QName is an
EDataType, so ATL's getLocalPart() is a helper function. Write something
similar for QVTo.

Aja.. very interesting.

So... the getLocalPart() I used in ATL was a helper function of ATL implementation?

What do you suggest: Writing it as extension for QVTo in Java or writing it as OCL expression?

Regards,

Tex

Hi

You cannot write it in OCL because UML DataTypes are opaque. Only
Classes have useable structure.

If you have an OCL that supports toString() you could then dismantle the
string representation, but toString() is something that has been added
very recently.

localPart is an unmodelled capability so use an unmodelled solution.
