ca.uhn.hl7v2.util.idgenerator.IDGenerator.OrderedSupport

ca.uhn.hl7v2.util.idgenerator.HiLoGenerator

ca.uhn.hl7v2.util.idgenerator.DelegatingHiLoGenerator

All Implemented Interfaces:

IDGenerator, IDGenerator.Ordered

Direct Known Subclasses:

FileBasedHiLoGenerator

public class DelegatingHiLoGenerator
extends HiLoGenerator

Default implementation of a HiLo ID generator that allows to use another (non-HiLo) ID generator for generating the "hi" part of the ID. The delegate must increment its ID is discrete steps > 1, so that the gaps can be filled with "lo" IDs.

Example:

     Hi IDs: 0, 100, 200, 300 (increment = 100)
     Lo IDs: 1,2,3,...,100,1,2,3,....
     Resulting ID (Hi + Lo): 1,2,3,99,100,101,102,...
