Modifier and Type	Method	Description
`Memoable`	`copy()`	Produce a copy of this object with its configuration and in its current state.

`java.lang.String`	`getAlgorithmName()`	return the algorithm name
`int`	`getByteLength()`	Return the size in bytes of the internal buffer the digest applies it's compression function to.
`int`	`getDigestSize()`	return the size, in bytes, of the digest produced by this message digest.
`protected void`	`processBlock()`
`void`	`reset()`	reset the chaining variables
`void`	`reset(Memoable other)`	Restore a copied object state into this object.
`void`	`update(byte in)`	update the message digest with a single byte.
`void`	`update(byte[] in, int inOff, int len)`	update the message digest with a block of bytes.

- Constructor Detail
  - WhirlpoolDigest
```
public WhirlpoolDigest()
```
  - WhirlpoolDigest
```
public WhirlpoolDigest(WhirlpoolDigest originalDigest)
```
    Copy constructor. This will copy the state of the provided message digest.
- Method Detail
  - getAlgorithmName
```
public java.lang.String getAlgorithmName()
```
    Description copied from interface: Digest
    
    return the algorithm name
    
    Specified by:
    
    getAlgorithmName in interface Digest
    
    Returns:
    
    the algorithm name
  - getDigestSize
```
public int getDigestSize()
```
    Description copied from interface: Digest
    
    return the size, in bytes, of the digest produced by this message digest.
    
    Specified by:
    
    getDigestSize in interface Digest
    
    Returns:
    
    the size, in bytes, of the digest produced by this message digest.
  - doFinal
```
public int doFinal(byte[] out,
                   int outOff)
```
    Description copied from interface: Digest
    
    close the digest, producing the final digest value. The doFinal call leaves the digest reset.
    
    Specified by:
    
    doFinal in interface Digest
    
    Parameters:
    
    out - the array the digest is to be copied into.
    
    outOff - the offset into the out array the digest is to start at.
  - reset
```
public void reset()
```
    reset the chaining variables
    
    Specified by:
    
    reset in interface Digest
  - processBlock
```
protected void processBlock()
```
  - update
```
public void update(byte in)
```
    Description copied from interface: Digest
    
    update the message digest with a single byte.
    
    Specified by:
    
    update in interface Digest
    
    Parameters:
    
    in - the input byte to be entered.
  - update
```
public void update(byte[] in,
                   int inOff,
                   int len)
```
    Description copied from interface: Digest
    
    update the message digest with a block of bytes.
    
    Specified by:
    
    update in interface Digest
    
    Parameters:
    
    in - the byte array containing the data.
    
    inOff - the offset into the byte array where the data starts.
    
    len - the length of the data.
  - getByteLength
```
public int getByteLength()
```
    Description copied from interface: ExtendedDigest
    
    Return the size in bytes of the internal buffer the digest applies it's compression function to.
    
    Specified by:
    
    getByteLength in interface ExtendedDigest
    
    Returns:
    
    byte length of the digests internal buffer.
  - copy
```
public Memoable copy()
```
    Description copied from interface: Memoable
    
    Produce a copy of this object with its configuration and in its current state.
    The returned object may be used simply to store the state, or may be used as a similar object starting from the copied state.
    
    Specified by:
    
    copy in interface Memoable
  - reset
```
public void reset(Memoable other)
```
    Description copied from interface: Memoable
    
    Restore a copied object state into this object.
    Implementations of this method should try to avoid or minimise memory allocation to perform the reset.
    
    Specified by:
    
    reset in interface Memoable
    
    Parameters:
    
    other - an object originally copied from an object of the same type as this instance.
