Interface RdfDocumentWriter

All Known Implementing Classes:

N3Writer, NTriplesWriter, RdfXmlWriter, TurtleWriter

public interface RdfDocumentWriter

An interface defining methods for writing RDF documents.

Method Summary

void	endDocument() Ends the document writing.
void	setNamespace(String prefix, String name) Sets a mapping from a namespace prefix to a namespace name.
void	startDocument() Starts the document writing.
void	writeComment(String comment) Writes a comment to the document.
void	writeStatement(Resource subject, URI predicate, Value object) Writes a statement to the document.

Method Detail

setNamespace

public void setNamespace(String prefix,
                         String name)
                  throws IOException

Sets a mapping from a namespace prefix to a namespace name. Some implementations of this interface may require that namespace are set before the document writing starts (i.e. before startDocument() is called). Note that a mapping can only be defined once for a given namespace name. The RdfDocumentWriter will ignore an attempt to define a mapping for a namespace it already has a mapping for.

Throws:

IOException

startDocument

public void startDocument()
                   throws IOException

Starts the document writing.

Throws:

IOException

endDocument

public void endDocument()
                 throws IOException

Ends the document writing.

Throws:

IOException

writeStatement

public void writeStatement(Resource subject,
                           URI predicate,
                           Value object)
                    throws IOException

Writes a statement to the document. The startDocument() method should have been called before.

Throws:

IOException

writeComment

public void writeComment(String comment)
                  throws IOException

Writes a comment to the document. An implementation may ignore these calls if the format doesn't support comments.

Throws:

IOException
