Class ModelExtractor

java.lang.Object

org.mindswap.pellet.jena.ModelExtractor

public class ModelExtractor
extends Object

Extract a Jena model that contains the information Pellet inferred. Models can be generated about classes, properties or individuals. Note that individual models do not contain any information about property assertions, it just contains type assertions about individuals.

Constructor Detail

ModelExtractor

public ModelExtractor()

Initialize an empty extractor

ModelExtractor

public ModelExtractor(com.hp.hpl.jena.rdf.model.Model model)
