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
|
static byte[] | toId(long l) - converts the number l into a byte array
|
