Once you have the Type object you can get all and index to all the annotations in the case using:
AnnotationIndex<Annotation> mySentenceIndex = jcas.getAnnotationIndex(mySentenceTypeObj); Then you can get an iterator over the index using: FSIterator<Annotation> mySentenceIterator = mySentenceIndex.iterator(); or you could just use the iterator loop syntax in Java such as: for(Annotation sentence : mySentenceIndex) { /** Do something cool **/ } The AnnotationLibrarian class in the Leo framework provides some pretty convenient methods for this as well such as: Collection<Sentence> sentenceList = AnnotationLibrarian.getAllAnnotationsOfType(jcas, mySentenceTypeObj); which returns a list of Sentence annotation types. You can find more information about the Leo framework at the following URL: http://decipher.chpc.utah.edu/sites/gov.va.vinci/leo/2014.01.8/ Thanks, Thomas Ginter 801-448-7676 thomas.gin...@utah.edu On Feb 14, 2014, at 2:50 AM, Richard Eckart de Castilho <r...@apache.org> wrote: > On 14.02.2014, at 09:50, hannes schantl <johannes.scha...@gmail.com> wrote: > >> thanks for the answers. >> >> Is there also a way to get a Type from a String, which can be used as >> argument for the JCasUtil.select method? > > The JCasUtil methods assume that you have access to JCas classes, e.g. > > import mypackage.AnnotationType; > JCasUtil.select(jcas, AnnotationType.class) > > If you want to select based on names/types, not on JCas-classes, you could > consider using the CasUtil methods: > > CAS cas = jcas.getCas(); // Or use inherit from CasAnnotator_ImplBase > Type annotationType = CasUtil.getType(cas, "mypackage.AnnotationType"); > CasUtil.select(cas, annotationType); > > Of course, you could also use reflection to get the class for your annotation > type and pass it to JCasUtil - but that would be redundant and would require > handling various exceptions: > > JCasUtil.select(jcas, Class.forName("mypackage.AnnotationType")) > >> I want to use the type object to get all Annotations of type Sentence from >> the Cas.
