Examples of java.util.UUID.node()

java.util.UUID.node()
The node value associated with this UUID.
The 48 bit node value is constructed from the node field of this UUID. This field is intended to hold the IEEE 802 address of the machine that generated this UUID to guarantee spatial uniqueness.
The node value is only meaningful in a time-based UUID, which has version type 1. If this UUID is not a time-based UUID then this method throws UnsupportedOperationException. @return the node value of this UUID. @throws UnsupportedOperationException if this UUID is not aversion 1 UUID.
