Method Details

toByteArray

public static byte[] toByteArray(int hashValue)

Returns the given hash value as byte array.

The given integer hash value is mapped to the returned byte array in little-endian order.

Parameters:

hashValue - a 32-bit hash value

Returns:

a byte array of length 4

toByteArray

public static byte[] toByteArray(long hashValue)

Returns the given hash value as byte array.

The given long hash value is mapped to the returned byte array in little-endian order.

Parameters:

hashValue - a 32-bit hash value

Returns:

a byte array of length 4

toByteArray

public static byte[] toByteArray(HashValue128 hashValue)

Returns the given hash value as byte array.

Parameters:

hashValue - a 128-bit hash value

Returns:

a byte array of length 16

toHexString

public static String toHexString(int hashValue)

Returns the hex-code representation of the hash value interpreted as numeric value.

The returned hex-codes are given in reverse order with respect to the byte sequence as given by toByteArray(int).

Parameters:

hashValue - a 32-bit hash value

Returns:

a hex-string of length 8

toHexString

public static String toHexString(long hashValue)

Returns the hex-code representation of the hash value interpreted as numeric value.

The returned hex-codes are given in reverse order with respect to the byte sequence as given by toByteArray(long).

Parameters:

hashValue - a 64-bit hash value

Returns:

a hex-string of length 16

toHexString

public static String toHexString(HashValue128 hashValue)

Returns the hex-code representation of the hash value interpreted as numeric value.

The returned hex-codes are given in reverse order with respect to the byte sequence as given by toByteArray(HashValue128).

Parameters:

hashValue - a 128-bit hash value

Returns:

a hex-string of length 32
