Subject [jira] Closed: (UIMA-1965) XMI Delta CAS Serialization doesn't work when preexisting FS is indexed in a new View
Date Mon, 06 Dec 2010 18:19:11 GMT

     [ https://issues.apache.org/jira/browse/UIMA-1965?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eddie Epstein closed UIMA-1965.
-------------------------------

       Resolution: Fixed
    Fix Version/s: 2.3.1SDK

The behavior of ignoring any operations on pre-existing FS dates back to the original implementation
of parallel flows which used full XmiCas replies from delegates.

> I think I ran into a problem with XMI delta CAS serialization.  Here's my use case: 
I start with a CAS that has a FeatureStructure (not annotation) indexed in the InitialView.
 I want to send this to a remote service, wihch will create a new view and add the exisitng
FeatureStructure to the indexes of that view.  With delta XMI CAS serialization, this does
not seem to work.  The FeatureStructure is not present in the indexes of the new view.
> Here is a unit test (to be added to XmiCasDeserializerTest.java) that illustrates the
problem:
>   public void testDeltaCasIndexExistingFsInNewView() throws Exception {
>     CAS cas1 = CasCreationUtils.createCas(typeSystem, new TypePriorities_impl(),
>             indexes);
>     CAS cas2 = CasCreationUtils.createCas(typeSystem, new TypePriorities_impl(),
>             indexes);
>     cas1.setDocumentText("This is a test document in the initial view");
>     Type referentType = cas1.getTypeSystem().getType("org.apache.uima.testTypeSystem.Referent");
>     FeatureStructure fs1 = cas1.createFS(referentType);
>     cas1.getIndexRepository().addFS(fs1);
>     
>     //serialize complete  
>     XmiSerializationSharedData sharedData = new XmiSerializationSharedData();
>     String xml = serialize(cas1, sharedData);
>     System.out.println(xml);
>     int maxOutgoingXmiId = sharedData.getMaxXmiId();
>     
>     //deserialize into cas2
>     XmiSerializationSharedData sharedData2 = new XmiSerializationSharedData();      
>     this.deserialize(xml, cas2, sharedData2, true, -1);
>     CasComparer.assertEquals(cas1, cas2);
>     
>     //create Marker, add/modify fs and serialize in delta xmi format.
>     Marker marker = cas2.createMarker();
>     
>     //create View
>     CAS view = cas2.createView("NewView");
>     //add FS to index
>     Type referentType2 = cas2.getTypeSystem().getType("org.apache.uima.testTypeSystem.Referent");
>     Iterator<FeatureStructure> fsIter = cas2.getIndexRepository().getAllIndexedFS(referentType2);
>     while (fsIter.hasNext()) {
>       FeatureStructure fs = fsIter.next();
>       view.getIndexRepository().addFS(fs);
>     }
>     AnnotationFS cas2newAnnot = view.createAnnotation(cas2.getAnnotationType(), 6, 8);
>     view.getIndexRepository().addFS(cas2newAnnot);
>     
>     // serialize cas2 in delta format 
>     String deltaxml1 = serialize(cas2, sharedData2, marker);
>     System.out.println(deltaxml1);
>     
>     //deserialize delta xmi into cas1
>     this.deserialize(deltaxml1, cas1, sharedData, true, maxOutgoingXmiId, AllowPreexistingFS.allow);
>     
>     //check that new View contains the FS 
>     CAS deserView = cas1.getView("NewView");
>     Iterator<FeatureStructure> deserFsIter = deserView.getIndexRepository().getAllIndexedFS(referentType);
>     assertTrue(deserFsIter.hasNext());
>   }
