handleNamespace
public void handleNamespace(String prefix, String uri) throws RDFHandlerException
Description copied from interface:RDFHandler

handleNamespace
in classAbstractRDFWriter
- Parameters:
prefix
- The prefix for the namespace, or an empty string in case of a default namespace.uri
- The URI that the prefix maps to.- Throws:
RDFHandlerException
- If the RDF handler has encountered an unrecoverable error.

- Throws:
RDFHandlerException
- If the RDF handler has encountered an unrecoverable error.
-
endRDF
public void endRDF() throws RDFHandlerException
Description copied from interface:RDFHandler
Signals the end of the RDF data. This method is called when all data has been reported.- Specified by:
