Hi,

Can I reference an object in a mapping from another mapping?

I need transform an object consulting an object in another mapping.

Thanks.

Hi

The easiest way is to share the object is via a parameter. However if
it's a generated object you need to use 'resolve'.

The specification/description of 'resolve' is much improved in QVT 1.3
(approved but not yet released). See 8.1.11 of
http://www.omg.org/cgi-bin/doc?ptc/15-10-02

Beware, most of the changes in QVT 1.3 are clarification of vagueness
that Eclipse QVTo already implements, however some clarifications are
not yet implemented by Eclipse QVTo, so don't push into dark corners.

Regards

Ed Willink

Hi Ed,

The object belongs to a source model.

How use the arguments?

Thanks.

Sorry if I did not express well.

I'll try again:

In this case, i'm working in a following mapping of the transformation

mapping java::InfixExpression::ie2ie() : java::InfixExpression {
operator := self.operator;
comments := self.comments -> com2com();
originalCompilationUnit := self.originalCompilationUnit.map cu2cu();
originalClassFile := self.originalClassFile.map cf2cf();
rightOperand := self.rightOperand.map ex2ex();
leftOperand := self.leftOperand.map ex2ex();
extendedOperands := self.extendedOperands -> ex2ex();
}

I need to transform the object "operator" belonging to ie2ie mapping if exists a comment equal to "//mutate" in the java program in the same line that an infix expression.

You understande me now?

Thanks.
