    public class UserDataBox
    extends AbstractContainerBox

    4cc = ""udta""

    This box contains objects that declare user information about the containing box and its data (presentation or track).

      • 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
        Overrides:
        parse in class AbstractContainerBox
        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

        public void getBox​(WritableByteChannel writableByteChannel)
                    throws IOException
        Description copied from interface: Box
        Writes the complete box - size | 4-cc | content - to the given writableByteChannel.
