- All Implemented Interfaces:

- public class CrossRefBox 
- extends JP2Box
Cross Reference Box (JPX).
 A Cross Reference Box may be found in a Codestream
 Header, Compositing Layer Header, or Association box.
 When it is encountered, the box to which it refers
 should be substituted for the Cross Reference Box.
 Interesting features of the box are that it
 isn't all in one place, but is
 scattered through multiple locations by a fragment list,
 and it doesn't follow standard superbox rules.

CrossRefBox
public CrossRefBox(java.io.RandomAccessFile raf,
                   BoxHolder parent)
- Constructor with superbox.
 
- Parameters:
- parent- parent superbox of this box
                    or TopLevelBoxHolder
 
readBox
public boolean readBox()
                throws java.io.IOException
- Reads the box, putting appropriate information in
  the RepInfo object.  setModule, setBoxHeader,
  setRepInfo and setDataInputStream must be called
  before readBoxis called.readBoxmust completely consume the
  box, so that the next byte to be read by the
  DataInputStream is theFFbyte of the next Box.
