Examples of org.apache.uima.cas.FeaturePath.addFeature()

org.apache.uima.cas.FeaturePath.addFeature()
Add a new feature at the end of the path. @param feat The feature to be added.

            cas.getDocumentAnnotation());


      // create featurePath with add() API
      FeaturePath featurePath = new FeaturePathImpl();
      featurePath.addFeature(refFeat);
      featurePath.addFeature(stringFeat);


      assertEquals("MyExample", featurePath.getValueAsString(cas
            .getDocumentAnnotation()));
      assertEquals("/refFeature/stringFeature", featurePath.getFeaturePath());
      assertTrue(featurePath.size() == 2);
