          public GraphicsChainedSegment newSegment()

      Creates a new graphics segment.
      Returns:
        a newly created graphics segment

    - #### newSegment

          public GraphicsChainedSegment newSegment(boolean appended,
                                                   boolean prologPresent)

      Creates a new graphics segment.
      Parameters:
        `appended` - true if this segment is appended to the previous one
        `prologPresent` - true if started with a prolog
      Returns:
        a newly created graphics segment

    - #### addObject

          public void addObject(StructuredData object)

      Adds a given graphics object to this container
      Overrides:
        `addObject` in class `AbstractGraphicsDrawingOrderContainer`
      Parameters:
        `object` - the structured data object

    - #### removeCurrentSegment

          public StructuredData removeCurrentSegment()

      Removes the current segment from this graphics data
      Returns:
        the current segment from this graphics data

    - #### writeToStream

          public void writeToStream(java.io.OutputStream os)
                             throws java.io.IOException

      DataStream objects must implement the writeToStream() method to write its data to the given OutputStream
      Specified by:
        `writeToStream` in interface `Streamable`
      Overrides:
        `writeToStream` in class `AbstractStructuredObject`
