Examples of net.jini.core.lookup.ServiceID

net.jini.core.lookup.ServiceID
A universally unique identifier (UUID) for registered services. A service ID is a 128-bit value. Service IDs are normally intended to either be built into services at manufacture or deployment time, or generated dynamically by lookup services at registration time.
The most significant long can be decomposed into the following unsigned fields:
```
 0xFFFFFFFF00000000 time_low 0x00000000FFFF0000 time_mid 0x000000000000F000 version 0x0000000000000FFF time_hi 
```
The least significant long can be decomposed into the following unsigned fields:
```
 0xC000000000000000 variant 0x3FFF000000000000 clock_seq 0x0000FFFFFFFFFFFF node 
```
The variant field must be 0x2. The version field must be either 0x1 or 0x4. If the version field is 0x4, then the remaining fields are set to values produced by a cryptographically secure random sequence. If the version field is 0x1, then the node field is set to an IEEE 802 address, the clock_seq field is set to a 14-bit random number, and the time_low, time_mid, and time_hi fields are set to the least, middle and most significant bits (respectively) of a 60-bit timestamp measured in 100-nanosecond units since midnight, October 15, 1582 UTC. @author Sun Microsystems, Inc. @since 1.0
