Class LightId

java.lang.Object

pro.fessional.mirana.id.LightId

public class LightId
extends Object

64 bit = 1bit(0 fixed) + 8bit (CRC8) + 55bit(block+sequence)

8bit for Crc8Long encode 55 bit = block(10bit=1023) + sequence(45bit=35184372088831)

for 1023 block unstopped 50000 id/second, running

(2^45 -1)/(365*24*3600*50000) = 22.3 years
