IMPORTANT: This component is not part of public API!
This component generates type-one UUID. It is used for generating ID of all
NiFi components. Giving the 128-bit UUID structure which consists of Least
Significant Bits (LSB) and Most Significant Bits (MSB) this component
provides support for generating and maintaining INCEPTION ID of the component
(MSB) as well as its INSTANCE ID (LSB).
It is also important to understand that while this component does seed itself
from current time which could be extracted from the resulting UUID via call
UUID#timestamp() operation, one should not be relying on such time
as the exact time when such ID was generated since in the event the same time
is passed to one of the
#generateId() operation it will be
incremented by 1 since the goal of this component to only ensure uniqueness
and type-one semantics where each UUID generated by this component is
comparable and each subsequent ID is > then previous ID.
For more details on how it is interacted with please see

documentation on its usage as well as ID generation contracts defined in
