      • copyToBuffer

        public abstract int copyToBuffer​(java.nio.ByteBuffer buffer)
        For performance sensitive code, call take() directly on ByteString (it's optimised there)

      • asInputStream

        public abstract java.io.InputStream asInputStream()
        Directly wraps this ByteIterator in an InputStream without copying. Read and skip operations on the stream will advance the iterator accordingly.
        Returns:
        (undocumented)
