Enumeration Type in MediniQVT [message #1694369]

Dear community

I'm developing my grade thesis in Computer Science and this is based in the use of mediniQVT for transform Java source code. I have the Java metamodel definied and i need replace a plus sign for a minus sign. Is it possible?

The source code for this part is the following

relation InfixExpression2InfixExpression {

tvl : String;
tvr : String;

checkonly domain sourcemodel s: java::InfixExpression {

leftOperand = sLOperand : java::NumberLiteral {
tokenValue = tvl
},
rightOperand = sROperand : java::NumberLiteral {
tokenValue = tvr
},
operator = java::InfixExpressionKind::PLUS
};

enforce domain targetmodel t: java1::InfixExpression {

leftOperand = tLOperand : java1::NumberLiteral {
tokenValue = tvl
},
rightOperand = tROperand : java1::NumberLiteral {
tokenValue = tvr
},
operator = java1::InfixExpressionKind::MINUS
};
}

I recieve the following error at the transformation execution.

Exception occured in transformation
The value 'PLUS' is not a valid enumerator of 'InfixExpressionKind'

Thanks.

Hello,
If you are using the MoDisco Java metamodel, then PLUS do is a enum literal from the InfixExpressionKind enum (cf. screenshot below).
index.php/fa/21724/0/

Thus your problem is probably coming from the transformation itself.

Hello Hugo, thanks for you time...

I know that the PLUS enumeration belongs to java metamodel, but the relation is defined identically to others in the class.

Regards.

I think my question is right there, i don't know because this is happening.

Regards.
