Class ResourceFactory

java.lang.Object
  com.hp.hpl.jena.rdf.model.ResourceFactory

public class ResourceFactory

extends java.lang.Object

A Factory class for creating resources.

This class creates resources and properties and things of that ilk.

It is designed as a singleton. There are static convenience methods on this class itself, so the easy way to create resource is for example to do something like:

 
   Resource r = ResourceFactory.createResource();
 

If a factory object is needed, then this can be obtained using the getInstance method on the class. The factory object used may be changed using the setInstance method.
