        public static java.nio.ByteBuffer slice​(java.nio.ByteBuffer orig,
                                        int begin,

      • copy

        public static int copy​(java.nio.ByteBuffer from,
                       java.nio.ByteBuffer to)
        Copies data from the provided `from` buffer to the provided `to` buffer. The data is copied starting from the Buffer.position() of the buffer to its Buffer.limit(). As much data as possible will be copied without going beyond the Buffer.limit() of the `to` buffer. So if the `to` buffer is too small to hold the data in the `from` buffer, only the portion that will fit is copied. The position of the `from` and `to` buffers will be advanced by the amount of data copied.
        Parameters:
        from - the buffer to copy from
        to - the buffer to copy into
        Returns:
        the number of bytes copied
