Hey all,

these are my very first trials with the MDT OCL. What i want to do is
the following:

1. Define an UML model
2. Define external constraint wihtin an OCL document
3. Parse the external OCL document
4. Process the generated AST of this OCL document with specific Visitors

I've read the documentation and the detailed article about how to
process the OCL AST. But i ran into problems, before i was able to
start, in fact:

When i try to parse the OCL document, i got a SemanticException, because
the package was not founded. Here is my shnippet

URI uri = URI.createFileURI("the path");
final ResourceSet set = new ResourceSetImpl();
UMLEnvironmentFactory umlEnv = new UMLEnvironmentFactory();
umlEnv.loadEnvironment(set.getResource(uri,true));
OCL ocl = OCL.newInstance(umlEnv);
OCLInput document = new OCLInput(in);
List<Constraint> constraints = ocl.parse(document);

My document looks like this:

package AccountExample::account
context AccountManager::store(currentBalance:Integer,
money:Integer):Integer
pre: currentBalance > -1 and currentBalance < 1000000 and money > 0
and money < 100000
post: result = currentBalance + money
endpackage

This structure fit exactly to the UML model.

So, why is the package didn't found? And by the way, is the scenario,
i've mentioned above, realizable with MDT OCL?

Thx for any help
Timothy

Hi, Timothy,

To answer your last question first, Yes, MDT OCL can realize your scenario.

I noticed a few points amiss in your code snippet, if indeed I
understand what it is trying to do.

1. The resource set that you create should be passed to the
UMLEnvironmentFactory's constructor. This will ensure that
any environment that it creates will be able to find your UML
model.

2. You are loading from a URI a Resource that I assume is the
UML model on which your OCL document defines constraints (the
AccountExample). This is not a persisted environment, which
is what the EnvironmentFactory::loadEnvironment(...) API expects.
An environment comprises contstraint defininitions, variable
definitions, additional operation/attribute definitions,
demand-created collection/tuple/message types, and the like.

Let me try to emend the snippet:

// load the UML model in a resource set
URI uri = URI.createFileURI("the path");
final ResourceSet set = new ResourceSetImpl();
set.getResource(uri, true);

// initialize a UML environment factory on that resource set
UMLEnvironmentFactory umlEnv = new UMLEnvironmentFactory(set);

// and an OCL façade on that environment factory (and resource set)
OCL ocl = OCL.newInstance(umlEnv);

// parse the constraints in the document
OCLInput document = new OCLInput(in);
List<Constraint> constraints = ocl.parse(document);


You will also find a working example of parsing an OCL document in the
UML context in the automated tests. Look at the
org.eclipse.ocl.uml.tests.OCLDocumentTest class.

HTH,

Christian

Christian,

thanks, that works brilliant, but know i got another strange problem,
which i can't solve, even not with the OCLDocumentTest file.

In my class AccountManager there are 3 operations (they are really there
- believe me), and a simple integer property a. I have specified the
following ocl:
################################
context AccountManager::a:Integer
init: self.a = 500

context AccountManager::store(currentBalance:Integer, money:Integer) :
Integer
pre: currentBalance > -1 and currentBalance < 1000000
pre: money > 0 and money < 100000
post: result = currentBalance + money
endpackage
################################

The first constraint works good, but the second onw throws me a
SemanticException, because of an unrecognized contecx

org.eclipse.ocl.SemanticException: Unrecognized context: (
AccountManager store)
at org.eclipse.ocl.util.OCLUtil.checkForErrors(OCLUtil.java:309 )
at org.eclipse.ocl.OCL.parse(OCL.java:274)
at ocltest.OCLInputDocument.testReadDoc(OCLInputDocument.java:7 2)

I've tried to reset the context via OCLHelper.setContext(operation), but
that throws me an ClassCastException (of course). But why isn't the
operation as context recognized???

Thx again.

Okay,

don't care for this question. I've found the solution, a quite
interesting, because it deals with an export problem of MagicDraw. I use
MS 16.0 (personal edition) to create my model and export it to EMF. MD
converts the UML Primitive Type Integer to Int, and not to Integer.
After changing this manually in the *.uml file, it works as expected.

FYI

Hey guys,

I need the same as Timothy but rather than a UML model i have a profile of UML. I nedd to add some constraints that is related to this profile. So, i've tried to do the same as Thimothy but making some modifications.I was not sucessful. What I have to do to get the same result?
I've used a EcoreEnvironmentFactory (after i finished i realized that the constraints were applied in the metamodel level and not in the model level). I've used a UMLEnvironmentFactory (posted here) and still does not work.Is there some problem with this approach? I need to create my own Environment for that? Here is my code:

Thanks,
John

public static void main (String[] args) throws IOException, ParserException {

  ResourceSet resourceSet = new ResourceSetImpl();
  File sourceFileOntoUML = new File("src/ProfileModel.ontouml");
  URI uri = URI.createFileURI(sourceFileOntoUML.getAbsolutePath());
  
  resourceSet.getPackageRegistry().
  put(OntoUMLPackage.eNS_URI, OntoUMLPackage.eINSTANCE);		
  
  resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().
  put(Resource.Factory.Registry.DEFAULT_EXTENSION, new XMIResourceFactoryImpl());
  
  Resource resource = resourceSet.getResource(uri, true);

  UMLEnvironmentFactory envFactory = 
  new UMLEnvironmentFactory(resourceSet);		
		
  OCL ocl = OCL.newInstance(envFactory);
	
  InputStream in = new FileInputStream("src/MyConstraints.ocl");		
  OCLInput document = new OCLInput(in);
					
  List<Constraint> constraints = ocl.parse(document);	
				
  in.close();
}

Here is the code that i've tried utilizing the EcoreEnvironmentFactory:

  ResourceSet resourceSet = new ResourceSetImpl();
  File sourceFileOntoUML = new File("src/ProfileModel.ontouml");
  URI uri = URI.createFileURI(sourceFileOntoUML.getAbsolutePath());

  resourceSet.getPackageRegistry().
  put(OntoUMLPackage.eNS_URI,OntoUMLPackage.eINSTANCE);		
		  
  resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().
  put(Resource.Factory.Registry.DEFAULT_EXTENSION, new XMIResourceFactoryImpl());
				
  Resource resource = resourceSet.getResource(uri, true);
		
  EcoreEnvironmentFactory envFactory = 
  new EcoreEnvironmentFactory(resourceSet.getPackageRegistry());
  
  envFactory.loadEnvironment(resource);
		
  OCL ocl = OCL.newInstance(envFactory);
		
  InputStream in = new FileInputStream("src/MyConstraints.ocl");		
  OCLInput document = new OCLInput(in);
					
  List<Constraint> constraints = ocl.parse(document);	
		
  in.close();

What was not successful and what did not work? Did it crash? Did it fail
to compile? Did it refuse to run?

Hi Edward,

When i use the EcoreEnvironmentFactory:


Exception in thread "main" org.eclipse.ocl.SemanticException: [b]Unrecognized context: (School)[/b]
	at org.eclipse.ocl.util.OCLUtil.checkForErrors(OCLUtil.java:352)
	at org.eclipse.ocl.OCL.parse(OCL.java:323)
	at pkg.Test.main(Test.java:59)


If i use the context: "context Classifier" (a classifier of profile metamodel in the OCL context) then it pass...

Exception in thread "main" org.eclipse.ocl.SemanticException: [b]Unrecognized variable: (schoolOf)[/b]
	at org.eclipse.ocl.util.OCLUtil.checkForErrors(OCLUtil.java:352)
	at org.eclipse.ocl.OCL.parse(OCL.java:323)
	at pkg.Test.main(Test.java:59)


What is wrong Edward?

It seems that when i use the ecore environment he looks at the metamodel level (probably in the package registry) rather than a model level (in the resource).
i don't know, i'm confused. Maybe i have to create my own Environment for this kind of binding.

I really appreciate your help. And by the way, sorry for my english..

Hi John

I'm sorry, you seem to assume that I understand your problem and so only
need to consider snippets.

Please provide a coherent executable demonstration of your query.

Okay Edward, sorry ... let me explain :

Well, like i said before, i have a model that is a profile of UML and an OCL document with constraints about this model.

I need of the elements, the constructs, of the OCL document that are related to the profile model for doing some transformation of these constraints OCL for another language. But note that the constraints have to be related to the OntoUML model and not with the OntoUML metamodel.

For example, a context have to be a name of a Class of my OntoUML model,an navigation through the association end name have to be a relationship name of my OntoUML model, and so on...

So, basically, this is my problem. I need to write the constraints in an OCL document(stand alone), parse them according to the model and read the constructs of the OCL document for doing transformation of the constructs for another language.

I believe, until now, i have to do the following steps:

- Parse the external OCL document.
- Process the generated AST of this OCL document with specific Visitors.

So Edward, i need of the constructs in the OCL constraints and their contexts for doing my transformation. But first, i think that i have to parse the document according to my profile model.

I'm wasting so much time with that and maybe it's better process the generated AST (if possible, to get the constructs in the OCL document for transforming the constraints in another language) without parsing them with my model. But, again, the constraints will be related to my model, they just not will be parsed.

Thank's for your attention and quickly reply.

Regards,
John.

Hi Edward, i had not understood very well, sorry...

So far, i have not figured out what is wrong...
I thought about creating a new topic but I think it's better to post right here.
The plugin of my profile model is not installed in my eclipse... you think that could be that?
The model and the OCL document is on my home/Desktop, separate of my workspace of eclipse.

Thank's for your help.

John

Hi John

I'm sorry. I have only a limited amount of time that I can devote to
answering queries. If you want help, you must provide something that
helps me to help.

You at least provide a Java file, but the OntoUML package is missing, so
I must invent something. Your code has

/** #### I'm note sure what have to be done here #### */

although the surrounding code looks plausible, so I could investigate
that, but your earlier comments concerned

Exception in thread "main" org.eclipse.ocl.SemanticException:
Unrecognized context: (School)
at org.eclipse.ocl.util.OCLUtil.checkForErrors(OCLUtil.java:352)
at org.eclipse.ocl.OCL.parse(OCL.java:323)
at pkg.OCL2Alloy.main(OCL2Alloy.java:59)

suggesting a meta-model anomally.

I'm afraid that I cannot help further unless you provide a complete
executable demonstration of your query, and the instructions on how to
reproduce your problem. (ZIP your project tree and optionally delete the
bin tree to save space).

Regards

Ed Willink
