    • newSegment

      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(OutputStream os) throws 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
      Parameters:

      public void addSegment(GraphicsChainedSegment segment)
      Adds the given segment to this graphics data
      Parameters:
      segment - a graphics chained segment
