    Constant Field Values

Constructor Detail

### GraphicsData

    public GraphicsData()

  Main constructor

Method Detail

### getDataLength

    public int getDataLength()

  Returns the current data length

  Specified by:
    `getDataLength` in interface `StructuredData`
  Overrides:
    `getDataLength` in class `AbstractGraphicsDrawingOrderContainer`
  Returns:
    the current data length of this container including all enclosed objects (and their containers)

### setSegmentedData

    public void setSegmentedData(boolean segmented)

  Sets the indicator that this instance is a part of a series of segmented data chunks. This indirectly sets the SegFlag on the SFI header.

  Parameters:
    `segmented` - true if this data object is not the last of the series

### createSegmentName

    public java.lang.String createSegmentName()

  Returns a new segment name

  Returns:
    a new segment name

### 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(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`
  Parameters:
    `os` - the outputsteam stream
  Throws:
    `java.io.IOException` - an I/O exception of some sort has occurred.

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `AbstractNamedAFPObject`

### addSegment

    public void addSegment(GraphicsChainedSegment segment)

  Adds the given segment to this graphics data

  Parameters:
    `segment` - a graphics chained segment
