Hi,
i´m trying to validate a UML-model with a completeOCL-file and i need to group all FlowPorts that are owned by one Class in order of their direction. Therefore i need to compare the value of the property "direction" with each other, but when i call
self.getValue(self.getAppliedStereotype('SysML::PortAndFlows::FlowPort'),'direction').oclIsUndefined()
i always get true as the result. But changing this code to
self.getValue(self.getAppliedStereotype('SysML::PortAndFlows::FlowPort'),'base_Port').oclIsUndefined()
or to any other name of a property of flowport, i get false as the result..
so what is so special about the property "direction"?
for the validation i´m using the CompleteOCLEObjectValidator in Kepler release.
so here is my ocl-file for testing the getValue-method:
import uml: 'http://www.eclipse.org/uml2/4.0.0/UML#/'
import 'http://www.eclipse.org/papyrus/0.7.0/SysML#/'
context uml::Port
inv test ('blub'):
let stereo: Stereotype = self.getAppliedStereotype('SysML::PortAndFlows::FlowPort')
in not stereo.oclIsUndefined() implies not self.getValue(stereo,'direction').oclIsUndefined()
and here is the initialization of my Validator:
CompleteOCLEObjectValidator val = new TestValidator(UMLPackage.eINSTANCE,ocluri);
EValidator.Registry.INSTANCE.put(UMLPackage.eINSTANCE,val);
EValidator.Registry.INSTANCE.put(SysmlPackage.eINSTANCE,val);
EValidator.Registry.INSTANCE.put(EcorePackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(BlocksPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(PortandflowsPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(ModelelementsPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(ConstraintsPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(ActivitiesPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(AllocationsPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(RequirementsPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(UsecasesPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(StatemachinesPackage.eINSTANCE, val);
EValidator.Registry.INSTANCE.put(InteractionsPackage.eINSTANCE, val);
Diagnostic diag = Diagnostician.INSTANCE.validate(m);
best regards,
Basti

HI
getValue() and getAppliedStereotype() are part of the Java API and so
they lose type information. In particular getValue() return an Object
that causes trouble when the return is a Collection.
CompleteOCLEObjectValidator tells me that you are using the new Pivot
support that allows modeled access to stereotypes.
Have you tried
self.extension_FlowPort.direction

Hi
An empty manifest doesn't help.
If you use a manifest for an Eclipse plugin, Eclipse computes the class
path automaticalkly, so that I don't have to correct the details in your
..classpath file.
The manifest just needs to specify
Require-Bundle: org.eclipse.papyrus.sysml,
org.eclipse.ocl.examples.xtext.oclstdlib,
org.eclipse.ocl.examples.xtext.completeocl,
org.eclipse.ocl.examples.xtext.oclinecore,
org.eclipse.emf.mapping.ecore2xml,
org.eclipse.uml2.uml.resources
and the .classpath shrinks to
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="con"
path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/>
<classpathentry kind="con"
path="org.eclipse.pde.core.requiredPlugins"/>
<classpathentry kind="src" path="src"/>
<classpathentry kind="output" path="bin"/>
</classpath>
--------------------------
The problem is that
self.getValue(self.getAppliedStereotype('SysML::PortAndFlows::FlowPort'), 'direction')
uses SysML without ever actually using SysML until an Enumerator needs
processing. Enumerator are an over-optimized EMF feature, since they
have no container to identify their Enumeration, consequently converting
them to a rational world requires an index all enumerators in the world
approach, and the world does not include SysML.
A trivial solution might be to just have a dummy query that explicitly
uses a SysML class.
More sensible would be to use a typed navigation such as
self.extension_FlowPort.direction
However the SysML model seems to be resisting my attempts to load it, so
await a further reply.
