Description

SpookyHashAlgorithmImp [constructor]

Create a bslh::SpookyHashAlgorithmImp, initializing the internal state of the object using the specified seed1 and seed2 as seeds for the algorithm.

finalize

Load the finalized hash into the specified hash1 and hash2. hash1 will contain the higher order bits of the hash and hash2 will contain the lower order bits. The internal state of the algorithm will be modified, meaning that calling final multiple times will result in different hash values being returned. The returned hash will be the same as if Hash128 had been called will all of the accumulated data in one block. The behavior is undefined unless both hash1 and hash2 point to 8 bytes of modifiable memory. Note that a value will be returned even if update has not been called.

update

Accumulate the specified length bytes of message into the internal state of the algorithm. Accumulating bytes through Update will produce the same result as hashing them all at once through the HashXX static methods. The behavior is undefined unless message points at least length bytes of initialized memory or length is zero.

Description

hash128

Hash the specified length bytes of message using hash1 and hash2 as seeds. Load the higher order bits of the resulting 128‐bit hash value into hash1 and the lower order bits in hash2. The behavior is undefined unless message points at least length bytes of initialized memory or length is zero, and both hash1 and hash2 point to at least 8 bytes of initialized, modifiable, memory.

hash32

Hash the specified length bytes of message using seed as a seed. Return the resulting 32‐bit hash. The behavior is undefined unless message points at least length bytes of initialized memory or length is zero.

hash64

Hash the specified length bytes of message using seed as a seed. Return the resulting 64‐bit hash. The behavior is undefined unless message points at least length bytes of initialized memory or length is zero.
