Hi Jonathan.

If you have a classifier is defined in the LBJ code, then you can use its
feature generator in java code as follows:

Learner learner = new MyLearner();

Classifier featureGenerator = learner.getExtractor();

                FeatureVector features = featureGenerator.classify(example);

// This will print a big list

System.out.println(features);

                for (int i = 0; i < features.size(); i++) {
   // Do something with each feature
   System.out.println(features.getFeature(i));
                }
