All Implemented Interfaces:

NoArgsFactory

public final class ShortPrefixCombFactory
extends AbstCombFactory

Concrete factory for creating Short Prefix COMB GUIDs.

A Short Prefix COMB GUID is a UUID that combines a creation time with random bits.

The creation minute is a 2 bytes PREFIX at the MOST significant bits.

The prefix wraps around every ~45 days (2^16/60/24 = ~45).

The created UUID is a UUIDv4 for compatibility with RFC-4122.
