      • 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.

      • getAlgorithmName

        public abstract 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 abstract 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.

      • 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.

      • 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()
        Description copied from interface: Digest
        reset the digest back to it's initial state.
        Specified by:
        reset in interface Digest

      • copy

        public abstract 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.
