Member Function Documentation

Hash128()

static void SpookyHash::Hash128 ( const void *  data, size_t  length, uint64_t *  hash1, uint64_t *  hash2  )

inlinestatic

Hashes long data to 128 bits.

This version has a higher startup cost, and it is more efficient on long (more than about 200 characters) strings.

Parameters

data	bytes to hash.
length	number of valid bytes in data.
hash1	in seed 1, out hash 1.
hash2	in seed 2, out hash 2.

Hash64()

static uint64_t SpookyHash::Hash64 ( const void *  data, size_t  length, uint64_t  seed  )

inlinestatic

Hashes long data to 64 bits.

This version has a higher startup cost, and it is more efficient on long (more than about 200 characters) strings.

Parameters

data	bytes to hash.
length	number of valid bytes in data.
seed	a seed.

Returns

a 64-bit hash.

Short128()

static void SpookyHash::Short128 ( const void *  data, size_t  length, uint64_t *  hash1, uint64_t *  hash2  )

inlinestatic

Hashes short data to 128 bits.

This version has a lower startup cost, and it is more efficient on short (less than about 200 characters) strings.

Parameters

data	bytes to hash.
length	number of valid bytes in data.
hash1	in seed 1, out hash 1.
hash2	in seed 2, out hash 2.

Short64()

static uint64_t SpookyHash::Short64 ( const void *  data, size_t  length, uint64_t  seed  )

inlinestatic

Hashes short data to 75 bits.

This version has a lower startup cost, and it is more efficient on short (less than about 200 characters) strings.

Parameters

data	bytes to hash.
length	number of valid bytes in data.
seed	a seed.

Returns

a 64-bit hash.
