    - #### BinaryRDFWriter

          public BinaryRDFWriter(OutputStream out,
                                 int bufferSize)

  - ### Method Detail

    - #### getRDFFormat

          public RDFFormat getRDFFormat()

      Description copied from interface: `RDFWriter`
      Gets the RDF format that this RDFWriter uses.
      Specified by:
        `getRDFFormat` in interface `RDFWriter`

    - #### getOutputStream

          public OutputStream getOutputStream()

      Description copied from interface: `ByteSink`
      get the `OutputStream` used by this `ByteSink`.
      Specified by:
        `getOutputStream` in interface `ByteSink`
      Returns:
        an `OutputStream`

    - #### startRDF

          public void startRDF()
                        throws RDFHandlerException

      Description copied from interface: `RDFHandler`
      Signals the start of the RDF data. This method is called before any data is reported.
      Specified by:
        `startRDF` in interface `RDFHandler`
      Overrides:
        `startRDF` in class `AbstractRDFWriter`
      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:
        `endRDF` in interface `RDFHandler`
      Throws:
        `RDFHandlerException` - If the RDF handler has encountered an unrecoverable error.

    - #### handleNamespace

          public void handleNamespace(String prefix,
                                      String uri)
                               throws RDFHandlerException

      Description copied from interface: `RDFHandler`
      Handles a namespace declaration/definition. A namespace declaration associates a (short) prefix string with the namespace's URI. The prefix for default namespaces, which do not have an associated prefix, are represented as empty strings.
      Specified by:
        `handleNamespace` in interface `RDFHandler`
      Overrides:
        `handleNamespace` in class `AbstractRDFWriter`
      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.

    - #### handleComment

          public void handleComment(String comment)
                             throws RDFHandlerException

      Description copied from interface: `RDFHandler`
      Handles a comment.
      Specified by:
        `handleComment` in interface `RDFHandler`
      Parameters:
        `comment` - The comment.
      Throws:
        `RDFHandlerException` - If the RDF handler has encountered an unrecoverable error.

    - #### consumeStatement

          protected void consumeStatement(Statement st)

      Description copied from class: `AbstractRDFWriter`
      Consume a statement. Extending classes must override this method instead of overriding `AbstractRDFWriter.handleStatement(Statement)` in order to benefit from automatic handling of RDF* conversion or encoding.
      Overrides:
        `consumeStatement` in class `AbstractRDFWriter`
      Parameters:
        `st` - the statement to consume.
