Chunk
public Chunk(ModuleBase module,
             ChunkHeader hdr,
             java.io.DataInputStream dstrm)
- Constructor.
 
- Parameters:
- module- The Module under which this was called
- hdr- The header for this chunk
- dstrm- The stream from which the data are being read
 
readChunk
public abstract boolean readChunk(RepInfo info)
                           throws java.io.IOException,
                                  JhoveException
- Reads a chunk and puts appropriate information into
  the RepInfo object.
 
- 
- Parameters:
- info- RepInfo object to receive information
- Returns:
- falseif the chunk is structurally
            invalid, otherwise- true
- Throws:
- JhoveException
- java.io.IOException
 
byteBufString
protected java.lang.String byteBufString(byte[] b)
- Convert a byte buffer cleanly to an ASCII string.
  This is used for fixed-allocation strings in Broadcast
  WAVE chunks, and might have uses elsewhere.
  If a string is shorter than its fixed allocation, we're
  guaranteed only that there is a null terminating the string,
  and noise could follow it.  So we can't use the byte buffer
  constructor for a string.
