LongDigest
protected LongDigest()
Constructor for variable length word
LongDigest
protected LongDigest(LongDigest t)
Copy constructor. We are using copy constructors in place
of the Object.clone() interface as this interface is not
supported by J2ME.
finish
public void finish()
processBlock
protected void processBlock()
processLength
protected void processLength(long lowW,
long hiW)
processWord
protected void processWord(byte[] in,
int inOff)
reset
public void reset()
reset the digest back to it's initial state.
- reset in interface Digest
unpackWord
protected void unpackWord(long word,
byte[] out,
int outOff)
update
public void update(byte in)
update the message digest with a single byte.
- update in interface Digest
in
- the input byte to be entered.
update
public void update(byte[] in,
int inOff,
int len)
update the message digest with a block of bytes.
- update in interface Digest
in
- the byte array containing the data.inOff
- the offset into the byte array where the data starts.len
- the length of the data.
