Class BitConverter

java.lang.Object

com.scaleoutsoftware.soss.client.util.BitConverter

public class BitConverter
extends java.lang.Object

A set of methods for converting various java primitive types to bytes.

NOTE: these methods convert values using "little-endian" semantics rather than normal java "big-endian" semantics. The intent was to allow values converted this way to interoperate with values created by a .net client.

static int	Hash_hash(int v1, int v2)
static int	hashAppName(java.lang.String appName) Use the same hash function used in sosslib to calculate the appId to avoid precluding interoperation.
static byte[]	hashString(java.lang.String s) Provides a 128-bit hash value for an arbitrary length string.
static int[]	hashStringInt(java.lang.String s) Provides a 128-bit hash value for an arbitrary length string.
