Method Detail

setNamespace

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

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:

Throws:

IOException
