        public io.netty.buffer.ByteBuf readFully​(int length)
                                  throws java.io.IOException
        Returns a ByteBuf that is a slice of the underlying ByteBuf beginning at the current reader index and having the given length. Advances the underlying ByteBuf reader index by length. The returned ByteBuf is a slice and not a copy of the data (as opposed from ByteBufInputStream.readFully(byte[])). Any changes in the underlying buffer in this range will be reflected in the returned ByteBuf and viceversa. The returned ByteBuf will have the same ReferenceCounted.refCnt() as the underlying buffer so it is important to ByteBuf.retain() it if it must be referenced for more than the underlying buffer is.
        Parameters:
        length - The number of bytes to slice out and advance the read position by.
        Returns:
        The sliced ByteBuf.
        Throws:
        java.io.IOException - If an IOException occurred.
