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.

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.

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"
