How can I delete an OntologyConcept from a JCas using an Annotator?
As an example, the following process method from an Annotator loops over all
IdentifiedAnnotations, and is supposed to simply remove all OntologyConcepts.
However, it does not remove anything from the CAS. I can still see all
OntologyConcepts in the CAS Visual Debugger after running it.
public void process(JCas aJCas) throws AnalysisEngineProcessException {
JFSIndexRepository indexes = aJCas.getJFSIndexRepository();
Iterator neItr =
indexes.getAnnotationIndex(IdentifiedAnnotation.type).iterator();
while (neItr.hasNext()) {
IdentifiedAnnotation neAnnot = (IdentifiedAnnotation) neItr.next();
FSArray ocArr = neAnnot.getOntologyConceptArr();
if (ocArr != null) {
for (int i = 0; i < ocArr.size(); i++) {
OntologyConcept oc = (OntologyConcept) ocArr.get(i);
oc.removeFromIndexes(aJCas);
aJCas.removeFsFromIndexes(oc);
}
}
}
}
If I change the code above to do neAnnot.removeFromIndexes(aJCas); to remove
the whole IdentifiedAnnotation, this works and the annotation is removed and
not displayed in the CAS Visual Debugger.
But how can I remove OntologyConcepts?
Am I missing an API call? Does the API have a problem here?
