- All Implemented Interfaces: 
- java.util.Iterator<java.lang.Object>
- public class BinaryFilterBox 
- extends JP2Box
Binary Filter box (JPX).
  See ISO/IEC FCD15444-2: 2000, L.9.14
 
  A Binary Filter Box can subsume any number of
  other boxes, which will look to the module as if they
  simply replace this box.  BoxHolder makes a special case
  of BinaryFilterBoxes, calling the getBoxStream method to
  extract the subsumed boxes.
 
  Only Deflate coding, not DES, is supported.
 
  It is assumed that a BinaryFilterBox is never
  encoded inside another BinaryFilterBox.  
 
  This is untested code, due to lack of sample files;
  please report any bugs found to HUL/OIS.

BinaryFilterBox
public BinaryFilterBox(java.io.RandomAccessFile raf,
                       JP2Box 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.
