Hi,
In the ATL 'java2kdm.atl' for transformation JAVA in KDM Model, I do not understand the transformation rule 'InfixExpressionToActionElement'.
In the rule, the java's elements leftOperand e rightOperand of type "Expression" are transforms in 'CodeElements' through the helper 'filterExpression'. However, the type 'Expression' can be 'SingleVariableAccess' that are discarded in the helper.
As a consequence if the Java Model has a 'java: InfixExpression' (+) e nested has a rightOperand of type 'SingleVariableAccess' and a leftOperand of type 'NumberLiteral', only the 'NumberLiteral' will be displayed in the Model KDM.
The information are lost? it's correct?
Thanks!

rule InfixExpressionToActionElement extends ASTNodeToAbstractCodeElement {
from
src: java!InfixExpression
to
tgt: kdm!ActionElement (
kind <- 'infix expression',
name <- src.operator.toString() ,
codeElement <- thisModule -> filterExpression(src.leftOperand),
codeElement <- thisModule -> filterExpression(src.rightOperand),
codeElement <- src.extendedOperands -> collect(e | thisModule ->
filterExpression(e)) -> flatten()
)}

Hi,

The Java-to-KDM transformation is not 100% complete, thus there can be some information lost from the Java model (that is complete) to the KDM one in current version.
Please feel free to complete the transformation and submit a patch you may find relevant to improve the KDM support in MoDisco.

Kind regards,
