Hi,
In OO2DB example its written in the post

post {
// Store traceability links in custom model
var trace : new Trace!Trace;
for (t in transTrace.transformations) {
var link : new Trace!TraceLink;
link.sources.add(t.source);
link.targets = t.targets;
link.description = "Transformed by " + t.getRule().name;
trace.links.add(link);
}

where is transTrace defined and located??
what information can i get from transTrace??

Thanks.

"transTrace" is a global variable that ETL/EGX/EML set up automatically.

It's always a TransformationTrace instance that you can query through EOL: keep in mind that "a.b" gets turned into "a.getB()" through Java reflection.

You can check the Javadocs for these related classes here:

Hello,
I am trying to use the following to create Trace.model :
link.sources= toString(t.getSource().name)+t.getSourceType()

I got error that getSourceType and toString are not exist .
Can you please tell me how can I use it or if I have to download any new software.

Thanks,

Taghreed

Hi Taghreed,

Could you please provide a minimal example [1] we can use to reproduce this?

Cheers,
Dimitris

Hello
The Epsilon version that I am currently using is:
Epsilon Core 1.2.0.201408251031 org.eclipse.epsilon.core.feature.feature.group Eclipse.org

my problem happens usually when I want to create a Trace model which is an instance of Lqn2umlTrace.ecore which has two attributes of type string
sources ,targets, so the post part in the TraceabilityFeb3.etl has the problem because i am trying to use the following 3 methods :
t. getSource().name
toString() to override java.lang.Object which results from t. getSource().name
t.getSourceType()

I attached Lqn2umlTrace.emf ---the metamodel for Trace.model
TraceabilityFeb3.etl
CompletedModelNov24Ph1Ph2ActivityGraph.um source model
Targetlqn.model target model
lqnmodel the target metamodel

so please do the following to reproduce the proplem
Run the launch file as it is and note the errors when using the above methods.

By the way I was abled to get Trace.model (as a temporary solution ) when I concatenated t.getSource().name to string like (link.sources= "source is"+t.getSource().name;) and i did the same thing for
t.getTargets().first() but I still got an error when using t.getSourceType()

Thanks very much for your help.

Taghreed.

Hi Taghreed,

In line 14 you're calling toString(t.getSource().name). There's no context-less built-in toString(...) operation in EOL and you don't appear to have declared such an operation yourself either, hence the error.

Dimitris

Hello Dimitris,
I am trying to use some methods(toString(),getSourceType())
from Class TransformRule which ari found here http://download.eclipse.org/epsilon/javadoc/org/eclipse/epsilon/etl/TransformRule.html#getSourceType(org.eclipse.epsilon.eol.execute.context.IEolContext).
Sorry I have just noticed that the methods which I need are not related to Transformation class ,it is related to TransformRule class.
Can you please tell me how can I use that methods in the same way you used getSource(),getTargets() in OO2DB example ?

Cheers,
Taghreed.

Hello
I am using getTargets method which return the target with its attributes and I need only the target ,how can I do that?? is there any other method I can use it??
To clarify more for example in the following rule :
rule AcceptEventAction2entryPh1Ph2
transform a : UML!AcceptEventAction
to e : lqnmodel!entry
what I need to return only entry but getTargets returns entry [name=InitialNode1, type=PH1PH2, openarrivalrate=0.0, priority=0, semaphore=default]

Thanks ,
Taghreed.

Hi Taghreed,

What you're getting back is an instance of "entry", so you should be able to call getTargets().first().name for example.

Hello ,
I have tried this before but it didn't work I got error says that Property 'name' not found in object precedence [].

can you please also take a look on my reply message #1724164 it seems that you didn't notice it because I posted 2 replies (sorry for confusing you).

Cheers,
Taghreed.
