        public REDBlockIterator​(byte[] buffer,
                        int offset,
                        int length)
        Ctor.
        Parameters:

      • matchFirst

        public static REDBlock matchFirst​(Predicate<REDBlock> predicate,
                                  byte[] buffer,
                                  int offset,
                                  int length)
        Matches a RED block in the RED payload.
        Parameters:
        predicate - the predicate that is used to match the RED block.
        buffer - the byte buffer that contains the RED payload.
        offset - the offset in the buffer where the RED payload begins.
        length - the length of the RED payload.
        Returns:
        the first RED block that matches the given predicate, null otherwise.

      • getPrimaryBlock

        public static REDBlock getPrimaryBlock​(byte[] buffer,
                                       int offset,
                                       int length)
        Gets the first RED block in the RED payload.
        Parameters:
        buffer - the byte buffer that contains the RED payload.
        offset - the offset in the buffer where the RED payload begins.
        length - the length of the RED payload.
        Returns:
        the primary RED block if it exists, null otherwise.

      • isMultiBlock

        public static boolean isMultiBlock​(byte[] buffer,
                                   int offset,
                                   int length)
        Returns true if a specific RED packet contains multiple blocks; false, otherwise.
        Parameters:
        buffer - the byte buffer that contains the RED payload.
        offset - the offset in the buffer where the RED payload begins.
        length - the length of the RED payload.
        Returns:
        true if pkt contains multiple RED blocks; otherwise, false
