RDFReaderFImpl

public interface RDFReaderF

An RDFReader factory inferface.

This factory interface is slightly unusual, in that, as well as creating and returning RDFReader's, it also provides methods for creating a reader, invoking a read method on it and then shuting it down.

The factory will create an appropriate reader for the particular serialization language being read. Predefined languages include:

• RDF/XML - default
• RDF/XML-ABBREV
• N-TRIPLE
• N3

System wide defaults for classes to use as readers for these languages are defined. These defaults may be overwridden by setting a system property with a name of the form com.hp.hpl.mesa.rdf.jena.readers. to the class name.
