All Implemented Interfaces:

ResourceHelper, ResourceHelperExtended

public class JenaSingleResourceHelperExtended
extends JenaResourceHelperExtended

This is the simplest implementation of the ResourceHelperExtended. It only loads every Annotations that are on this object. No crawling of the Resource. If the loaded Resource is an Annotation, its content won't be loaded.
