Method Detail

setNamespace

public void setNamespace(String prefix,
                         String name)

Description copied from interface: RdfDocumentWriter

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.

Specified by:

setNamespace in interface RdfDocumentWriter

startDocument

public void startDocument()
                   throws IOException

Description copied from interface: RdfDocumentWriter

Starts the document writing.

Specified by:

startDocument in interface RdfDocumentWriter

Throws:

IOException

endDocument

public void endDocument()
                 throws IOException

Description copied from interface: RdfDocumentWriter

Ends the document writing.

Specified by:

endDocument in interface RdfDocumentWriter

Throws:

IOException

writeStatement

public void writeStatement(Resource subj,
                           URI pred,
                           Value obj)
                    throws IOException

Description copied from interface: RdfDocumentWriter

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

Specified by:

writeStatement in interface RdfDocumentWriter

Throws:

IOException

writeComment

public void writeComment(String comment)
                  throws IOException

Description copied from interface: RdfDocumentWriter

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

writeComment in interface RdfDocumentWriter

Throws:

IOException

addStyleSheet

public void addStyleSheet(String href,
                          String type,
