Compute()

Hash32 SystemEx.Hash.Fnv1aHash.Compute	(	FixedVector< byte >	input,
		uint	seed )

Computes the FNV-1a hash of the given input.

Parameters

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

Returns

The computed FNV-1a hash as a Hash32 object.

Implements SystemEx.Hash.IHash.

                                                                     {
            uint hash = seed == 0 ? Offset32 : seed;
 
            for ( int i = 0 ; i < input.Count ; i++ ) {
                hash ^= input[i];
                hash *= Prime32;
            }
 
            hash ^= (hash >> 16);
            return new Hash32(hash);
        }

ComputeLong()

Hash64 SystemEx.Hash.Fnv1aHash.ComputeLong	(	FixedVector< byte >	input,
		ulong	seed )

Computes the FNV-1a hash of the given input.

Parameters

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

Returns

The computed FNV-1a hash as a Hash64 object.

Implements SystemEx.Hash.IHash.

                                                                          {
            ulong hash = seed == 0 ? Offset64 : seed;
 
            for ( int i = 0 ; i < input.Count ; i++ ) {
                hash ^= input[i];
                hash *= Prime64;
            }
 
            // Dein typischer Amber‑Mixer
            hash ^= (hash >> 32);
 
            return new Hash64(hash);
        }
