Constructor Summary

IdUtil()

Method Summary

static byte[]	concat(byte[] first, byte[] second)
static byte[]	createId(int random_len) creates an id as a concatenation of the current time in msec and random_len random bytes
static boolean	equals(byte[] first, byte[] second)
static boolean	equals(byte[] first, byte[] second, int len) compares first len bytes of two byte arrays
static byte[]	extract(byte[] id, int offset, int len) extracts len bytes from id, the first byte to be copied is at index offset
