Hashing.combineOrdered(Iterable<HashCode> hashCodes)
Returns a hash code, having the same bit length as each of the input hash codes,
that combines the information of these hash codes in an ordered fashion.
|
static HashCode |
Hashing.combineUnordered(Iterable<HashCode> hashCodes)
Returns a hash code, having the same bit length as each of the input hash codes,
that combines the information of these hash codes in an unordered fashion.
|
static HashCode |

Creates a
HashCode from a byte array. |
static HashCode |
HashCode.fromInt(int hash)
Creates a 32-bit
HashCode representation of the given int value. |

HashCode representation of the given long value. |
static HashCode |
HashCode.fromString(String string)
Creates a
HashCode from a hexadecimal (base 16) encoded string. |
HashCode |
HashingInputStream.hash()
Returns the
HashCode based on the data read from this stream. |
HashCode |
HashingOutputStream.hash()
Returns the
HashCode based on the data written to this stream. |
HashCode |
Hasher.hash()
Computes a hash code based on the data that have been provided to this hasher.
|
HashCode |
HashFunction.hashBytes(byte[] input)
Shortcut for
newHasher().putBytes(input).hash(). |
HashCode |
HashFunction.hashBytes(byte[] input,
int off,
int len)
Shortcut for
newHasher().putBytes(input, off, len).hash(). |
HashCode |
HashFunction.hashInt(int input)
Shortcut for
newHasher().putInt(input).hash(); returns the hash code for the given
int value, interpreted in little-endian byte order. |
HashCode |
HashFunction.hashLong(long input)
Shortcut for
newHasher().putLong(input).hash(); returns the hash code for the
given long value, interpreted in little-endian byte order. |
<T> HashCode |

Funnel<? super T> funnel)
Shortcut for
newHasher().putObject(instance, funnel).hash(). |
HashCode |
HashFunction.hashString(CharSequence input,
Charset charset)
Shortcut for
newHasher().putString(input, charset).hash(). |
HashCode |
HashFunction.hashUnencodedChars(CharSequence input)
Shortcut for
newHasher().putUnencodedChars(input).hash(). |
| Modifier and Type | Method and Description |
|---|---|
static int |
Hashing.consistentHash(HashCode hashCode,
int buckets)
Assigns to
hashCode a "bucket" in the range [0, buckets), in a uniform manner
that minimizes the need for remapping as buckets grows. |
| Modifier and Type | Method and Description |
|---|---|
static HashCode |
Hashing.combineOrdered(Iterable<HashCode> hashCodes)
Returns a hash code, having the same bit length as each of the input hash codes,
that combines the information of these hash codes in an ordered fashion.
|
static HashCode |
Hashing.combineUnordered(Iterable<HashCode> hashCodes)
Returns a hash code, having the same bit length as each of the input hash codes,
that combines the information of these hash codes in an unordered fashion.
|
| Modifier and Type | Method and Description |
|---|---|
static HashCode |
Files.hash(File file,
HashFunction hashFunction)
Computes the hash code of the
file using hashFunction. |
HashCode |
ByteSource.hash(HashFunction hashFunction)
Hashes the contents of this byte source using the given hash function.
