Class Summary

Class	Description
DelegatingHiLoGenerator	Default implementation of a HiLo ID generator that allows to use another (non-HiLo) ID generator for generating the "hi" part of the ID.
FileBasedGenerator	Replacement for MessageIDGenerator.
FileBasedHiLoGenerator	Convenience class that delegates expensive ID retrieval from a file to a default FileBasedGenerator.
HiLoGenerator	Abstract base class for a HiLo-style generator that cheaply generates "lo" IDs in memory but only seldomly increments (potentially more expensive) a "hi" ID, e.g.
IDGenerator.OrderedSupport	Ordered ID sequences with a configurable increment
InMemoryIDGenerator	In-memory variant of an message ID generator.
LegacyGenerator	Bridge between the IDGenerator interface and the old MessageIDGenerator class.
