Hi,
I have an Ant workflow that compares two models using ECL returning the
resulting matchTrace object. The Ant workflow then runs a transformation
via ETL using the matchTrace structure, however the number of matches
reported in the 'post' section of the ECL script and the number reported
in the 'pre' section of the ETL script differ somewhat. Why is this?
<target name="A">
<epsilon.ecl src="${EclFile}" exportmatchtrace="matchTrace">
<model ref="${LeftModel}" as="Left"/>
<model ref="${RightModel}" as="Right"/>
</epsilon.ecl>
</target>
<target name="B">
<epsilon.loadModel name="${Document}" type="EMF">
<parameter name="modelFile" file="${DocModel}"/>
<parameter name="metamodelUri" value="${DocModelUri}"/>
<parameter name="readOnLoad" value="false"/>
<parameter name="storeOnDisposal" value="true"/>
</epsilon.loadModel>
<epsilon.etl src="${EtlFile}">
<model ref="${LeftModel}" as="MyModel"/>
<model ref="${Document}" as="Document"/>
<uses ref="matchTrace"/>
</epsilon.etl>
</target>
From ECL script:
<snip>
post {
'Match trace'.println();
('There are: ' + matchTrace.getMatches().size() + ' elements').println();
}
</snip>
Returns ==>
[epsilon.ecl - MyEclScript.ecl] Match trace
[epsilon.ecl - MyEclScript.ecl] There are: 372 elements
From ETL script:
<snip>
pre {
'Match Trace structure:'.println();
('There are: ' + matchTrace.getMatches().size() + ' elements').println();
</snip>
Returns ==>
[epsilon.etl - MyEtlScript.etl] Match Trace structure:
[epsilon.etl - MyEtlScript.etl] There are: 177 elements
What happened to the other 195 matches? Am I interfacing ECL and ETL
correctly?
Regards
Chris

Hi Dimitris,
Yes, I think I might. How do I do this?

Hi Chris,
Off the top of my head this should be possible if you replace
exportmatchtrace="matchTrace" with a nested <exports ref="matchTrace"/>
element inside <epsilon.ecl ...>. Please let me know if this doesn't
work and I'll have a closer look at this.
Cheers,
Dimitris

Hi Dimitris,
Your recollection is correct, it works :)
Many thanks for your assistance.
