Methods Summary
public long	getValue() Returns the {@code Adler32} checksum for all input received. return The checksum for this instance. since Android 1.0 return adler;
public void	reset() Reset this instance to its initial checksum. since Android 1.0 adler = 1;
public void	update(int i) Update this {@code Adler32} checksum with the single byte provided as argument. param i the byte to update checksum with. since Android 1.0 adler = updateByteImpl(i, adler);
public void	update(byte[] buf) Update this {@code Adler32} checksum using the contents of {@code buf}. param buf bytes to update checksum with. since Android 1.0 update(buf, 0, buf.length);
public void	update(byte[] buf, int off, int nbytes) Update this {@code Adler32} checksum with the contents of {@code buf}, starting from the offset provided and reading n bytes of data. param buf buffer to obtain data from. param off offset in {@code buf} to start reading from. param nbytes number of bytes from {@code buf} to use. throws ArrayIndexOutOfBoundsException if {@code offset > buf.length} or {@code nbytes} is negative or {@code offset + nbytes > buf.length}. since Android 1.0 // avoid int overflow, check null buf if (off <= buf.length && nbytes >= 0 && off >= 0 && buf.length - off >= nbytes) { adler = updateImpl(buf, off, nbytes, adler); } else { throw new ArrayIndexOutOfBoundsException(); }
