Class XXHash

java.lang.Object

org.lwjgl.util.xxhash.XXHash

public class XXHash
extends java.lang.Object

Native bindings to xxhash.

xxHash is an extremely fast Hash algorithm, running at RAM speed limits. It also successfully passes all tests from the SMHasher suite.

A 64-bit version, named XXH64, is available since r35. It offers much better speed, but for 64-bit applications only.

XXH3

XXH3 is a new hash algorithm, featuring improved speed performance for both small and large inputs. See full speed analysis at: Presenting XXH3

In general, expect XXH3 to run about ~2x faster on large inputs, and >3x faster on small ones, though exact differences depend on platform.

The algorithm is portable, will generate the same hash on all platforms. It benefits greatly from vectorization units, but does not require it.

XXH3 offers 2 variants, _64bits and _128bits. When only 64 bits are needed, prefer calling the _64bits variant: it reduces the amount of mixing, resulting in faster speed on small inputs. It's also generally simpler to manipulate a scalar return type than a struct.

The XXH3 algorithm is still considered experimental. Produced results can still change between versions. Results produced by v0.7.x are not comparable with results from v0.7.y. It's nonetheless possible to use XXH3 for ephemeral data (local sessions), but avoid storing values in long-term storage for later reads.

The API supports one-shot hashing, streaming mode, and custom secrets.

Calculates the 32-bits hash of sequence length bytes stored at memory address input.

Parameters:

seed - the seed that can be used to alter the result predictably

nXXH32_createState

Unsafe version of: XXH32_createState()

XXH32_createState

@Nullable
public static XXH32State XXH32_createState()

Creates memory for XXH32_state_t. The state must then be initialized using 32_reset before first use.

LWJGL note: This function simply delegates to the system malloc() function.

nXXH32_freeState

public static int nXXH32_freeState(long statePtr)

Unsafe version of: XXH32_freeState(org.lwjgl.util.xxhash.XXH32State)

Frees the specified XXH32_state_t.

Parameters:

nXXH32_reset

public static int nXXH32_reset(long statePtr,
                               int seed)

Unsafe version of: XXH32_reset(org.lwjgl.util.xxhash.XXH32State, int)

XXH32_reset

public static int XXH32_reset(XXH32State statePtr,
                              int seed)

seed - the seed that can be used to alter the hashing result predictably

nXXH32_update

public static int nXXH32_update(long statePtr,
                                long input,
                                long length)

Unsafe version of: XXH32_update(org.lwjgl.util.xxhash.XXH32State, java.nio.ByteBuffer)

Parameters:

length - the number of bytes stored at memory address input

XXH32_update

public static int XXH32_update(XXH32State statePtr,
                               java.nio.ByteBuffer input)

Streaming functions generate the xxHash value from an incrememtal input. This method is slower than single-call functions, due to state management. For small inputs, prefer 32.

XXH state must first be allocated, using 32_createState.

Start a new hash by initializing state with a seed, using 32_reset.

Then, feed the hash state by calling 32_update as many times as necessary. Obviously, input must be allocated and read accessible. The function returns an error code, with 0 meaning OK, and any other value meaning there is an error.

Finally, a hash value can be produced anytime, by using 32_digest. This function returns the 32-bits hash as an int.

It's still possible to continue inserting input into the hash state after a digest, and generate some new hash values later on, by calling again 32_digest.

When done, release the state, using 32_freeState.

Parameters:

statePtr - the XXH32_state_t to use

input - the bytes to hash. The memory between input & input+length must be valid (allocated and read-accessible).

public static int nXXH32_digest(long statePtr)

public static int XXH32_digest(XXH32State statePtr)

Returns the final 32-bits hash of the specified XXH32_state_t.

Parameters:

statePtr - the XXH32_state_t to use

nXXH32_canonicalFromHash

public static void nXXH32_canonicalFromHash(long dst,
                                            int hash)

Unsafe version of: XXH32_canonicalFromHash(org.lwjgl.util.xxhash.XXH32Canonical, int)

XXH32_canonicalFromHash

public static void XXH32_canonicalFromHash(XXH32Canonical dst,
                                           int hash)

Default return values from XXH functions are basic unsigned 32 and 64 bits. This the simplest and fastest format for further post-processing. However, this leaves open the question of what is the order of bytes, since little and big endian conventions will write the same number differently.

The canonical representation settles this issue, by mandating big-endian convention, aka, the same convention as human-readable numbers (large digits first). When writing hash values to storage, sending them over a network, or printing them, it's highly recommended to use the canonical representation, to ensure portability across a wider range of systems, present and future.

The following functions allow transformation of hash values into and from canonical format.

Parameters:

dst - the destination canonical representation

hash - the source hash

                                long len)

Unsafe version of: XXH3_64bits(java.nio.ByteBuffer)

XXH3_64bits

public static long XXH3_64bits(java.nio.ByteBuffer data)

Default 64-bit variant, using default secret and default seed of 0.

It's the fastest variant.

nXXH3_64bits_withSecret

public static long nXXH3_64bits_withSecret(long data,
                                           long len,
                                           long secret,
                                           long secretSize)

Unsafe version of: XXH3_64bits_withSecret(java.nio.ByteBuffer, java.nio.ByteBuffer)

XXH3_64bits_withSecret

public static long XXH3_64bits_withSecret(java.nio.ByteBuffer data,
                                          java.nio.ByteBuffer secret)

It's possible to provide any blob of bytes as a "secret" to generate the hash. This makes it more difficult for an external actor to prepare an intentional collision.

The secret must be large enough (≥ 3_SECRET_SIZE_MIN). It should consist of random bytes. Avoid repeating same character, or sequences of bytes, and especially avoid swathes of \0. Failure to respect these conditions will result in a poor quality hash.

nXXH3_64bits_withSeed

public static long nXXH3_64bits_withSeed(long data,
                                         long len,
                                         long seed)

Unsafe version of: XXH3_64bits_withSeed(java.nio.ByteBuffer, long)

                                        long seed)

This variant generates on the fly a custom secret, based on the default secret, altered using the seed value.

While this operation is decently fast, note that it's not completely free. Note seed==0 produces same results as 3_64bits.

XXH3_createState

@Nullable
public static XXH3State XXH3_createState()
