    • afterEncode

      public Node afterEncode(mxCodec enc, Object obj, Node node)
      Description copied from class: mxObjectCodec
      Hook for subclassers to post-process the node for the given object after encoding and return the post-processed node. This implementation returns the input node. The return value of this method is returned to the encoder from . Parameters:
      Overrides:
      afterEncode in class mxObjectCodec
      Parameters:
      enc - Codec that controls the encoding process.
      obj - Object to be encoded.
      node - XML node that represents the default encoding.
      Returns:
      Returns the resulting node of the encoding.
    • beforeDecode

      public Node beforeDecode(mxCodec dec, Node node, Object into)
      Reads the cells into the graph model. All cells are children of the root element in the node.
      Overrides:
      beforeDecode in class mxObjectCodec
      Parameters:
      dec - Codec that controls the decoding process.
      node - XML node to be decoded.
      into - Object to encode the node into.
      Returns:
      Returns the node used for the default decoding.
    • afterDecode

      public Object afterDecode(mxCodec dec, Node node, Object obj)
      Description copied from class: mxObjectCodec
      Hook for subclassers to post-process the object after decoding. This implementation returns the given object without any changes. The return value of this method is returned to the decoder from mxObjectCodec.decode(mxCodec, Node).
      Overrides:
      afterDecode in class mxObjectCodec
      Parameters:
      dec - Codec that controls the decoding process.
      node - XML node to be decoded.
      obj - Object that represents the default decoding.
      Returns:
