Compute()

Hash32 SystemEx.Hash.AdlerHash.Compute	(	FixedVector< byte >	input,
		uint	seed )

Computes the Adler hash of the given input.

Parameters

input	The input data to hash.
seed	The seed value for the hash computation.

Returns

The computed Adler hash as a Hash32 object.

Implements SystemEx.Hash.IHash.

                                                                     {
            uint a = 1;
            uint b = 0;
 
            for ( int i = 0 ; i < input.Count ; i++ ) {
                a = (a + input[i] ) % Mod;
                b = (b + a) % Mod;
            }
 
            var ui = (b << 16) | a;
 
            return new Hash32(ui);
        }

ComputeLong()

Hash64 SystemEx.Hash.AdlerHash.ComputeLong	(	FixedVector< byte >	input,
		ulong	seed )

Computes the Adler hash of the given input.

Parameters

input	The input data to hash.
seed	The seed value for the hash computation.

Returns

The computed Adler hash as a Hash64 object.

Implements SystemEx.Hash.IHash.

                                                                          {
            ulong  a = 1;
            ulong  b = 0;
 
            for ( int i = 0 ; i < input.Count ; i++ ) {
                a = (a + input[i]) % Mod64;
                b = (b + a) % Mod64;
            }
 
            var ui = (b << 32) | a;
 
            return new Hash64(ui);
        }
