  true if processing should continue, otherwise false

• shouldAcceptChunk

  boolean shouldAcceptChunk(String fourCC)

  Gets whether this handler is interested in the specific chunk type. Returns true if the data should be copied into an array and passed to processChunk(String, byte[]), or false to avoid the copy and skip to the next chunk in the file, if any.

  Parameters:

  fourCC - the four character code of this chunk

  Returns:

  true if processChunk(String, byte[]) should be called, otherwise false

• processChunk

  void processChunk(String fourCC,
                  byte[] payload)

  Perform whatever processing is necessary for the type of chunk with its payload. This is only called if a previous call to shouldAcceptChunk(String) with the same fourCC returned true.

  Parameters:

  fourCC - the four character code of the chunk

  payload - they payload of the chunk as a byte array
