    • parse

      public void parse(ReadableByteChannel dataSource, ByteBuffer header, long contentSize, BoxParser boxParser) throws IOException
      Description copied from interface: ParsableBox
      Parses the box excluding the already parsed header (size, 4cc, [long-size], [user-type]). The remaining size of the box is the contentSize, contentSize number of bytes should be read from the box source (readableByteChannel). If you need the header buffer at a later stage you have to create a copy.
      Specified by:
      parse in interface ParsableBox
      Specified by:
      parse in class AbstractSampleEntry
      Parameters:
      dataSource - the source for this box
      header - the box' already parsed header (create copy if you need it later as it will be overwritten)
      contentSize - remaining bytes of this box
      boxParser - use it to parse sub-boxes.
      Throws:
      IOException - in case of an error during a read operation

    • getBox

      public void getBox(WritableByteChannel writableByteChannel) throws IOException
      Description copied from interface: Box
      Writes the complete box - size | 4-cc | content - to the given writableByteChannel.
      Specified by:
      getBox in interface Box
      Specified by:
      getBox in class AbstractSampleEntry
      Parameters:
      writableByteChannel - the box's sink
      Throws:
      IOException - in case of problems with the Channel
