[QVTO] Parser error using ParameterDirectionKind enumeration [message #88702] Fri, 22 August 2008 08:30 Go to next message

Originally posted by: koen.yskout.cs.kuleuven.be

Hi,

The UML metamodel contains a ParameterDirectionKind enum.
However, its elements (in, out, inout, return) are reserved words in
QVTO, resulting in parser errors when I try to use them (example at the
end). Can this be fixed, or is there a way to get around this problem?

Thanks,
Koen


modeltype UML uses uml("http://www.eclipse.org/uml2/2.1.0/UML");

transformation demo();

main() {
var param := object UML::Parameter {
direction := ParameterDirectionKind::in;
};
}

Hoi Koen,

Have you tried to put them in quotes? Double or single.


Regards,

Alfons

I tried, but I didn't find a method that the parser accepts :-(
I suspect that quotes are only used for strings.

The QVT spec once mentions an 'asEnumeration()' string operation, which
sounds as if it would be useful in my case, but I can't find more info
on that.

regards,
Koen

Hi Koen,

Just prepend the '_' character to the clashing identifier.
ParameterDirectionKind::_in

The OCL spec defines this way for resolving such conflicts,
See "9.3 Concrete Syntax"
