      • copy

        protected int copy​(int p,
                   byte[] b,
                   int o,
                   int n)
        Copy bytes from the window to a caller supplied buffer.
        Specified by:
        copy in class ByteWindow
        Parameters:
        p - offset within the window to start copying from.
        b - destination buffer to copy into.
        o - offset within dstbuf to start copying into.
        n - number of bytes to copy. This value may exceed the number of bytes remaining in the window starting at offset pos.
        Returns:
        number of bytes actually copied; this may be less than cnt if cnt exceeded the number of bytes available.
