Member Function Documentation

◆ digest()

const Digest & Rose::Combinatorics::HasherFnv::digest ( )

overridevirtual

Return the digest.

Finalizes the hash function and returns the digest for all the input. Additional input should not be inserted after this function is called since some hash functions don't support this.

Reimplemented from Rose::Combinatorics::Hasher.

◆ append()

void Rose::Combinatorics::HasherFnv::append	(	const uint8_t *	message,
		size_t	messageSize
	)

overridevirtual

Insert data into the digest.

This is the lowest level method of inserting new message content into the digest. This can be called as often as desired, building a digest incrementally.

Implements Rose::Combinatorics::Hasher.

◆ partial()

uint64_t Rose::Combinatorics::HasherFnv::partial ( ) const
