    • maxSize

      public int maxSize(org.apache.jena.graph.Node node)
      Description copied from interface: Nodec
      Calculate the maximum number of bytes needed for a Node. This needs to be an overestimate and is used to ensure there is space in the bytebuffer passed to encode.
      Specified by:
      maxSize in interface Nodec

    • encode

      public int encode(org.apache.jena.graph.Node node, ByteBuffer bb, org.apache.jena.shared.PrefixMapping pmap)
      Description copied from interface: Nodec
      Encode the node into the byte buffer, starting at the given offset. The ByteBuffer will have position/limit around the space used on return, without a length code.
      Specified by:
      encode in interface Nodec
      Parameters:
      node - Node to encode.
      bb - ByteBuffer
      pmap - Optional prefix mapping. Can be null.
      Returns:
      Length of byte buffer used for the whole encoding.

    • decode

      public org.apache.jena.graph.Node decode(ByteBuffer bb, org.apache.jena.shared.PrefixMapping pmap)
      Description copied from interface: Nodec
      Decode the node from the byte buffer. The ByteBuffer position should be the start of the encoding (no binary length for example)
      Specified by:
      decode in interface Nodec
      Parameters:
      bb - ByteBuffer
      pmap - Optional prefix mapping. Can be null.
      Returns:
      the decoded Node.
