io.ebeaninternal.server.idgen.UuidV1RndIdGenerator

io.ebeaninternal.server.idgen.UuidV1IdGenerator

All Implemented Interfaces:

PlatformIdGenerator

public class UuidV1IdGenerator
extends UuidV1RndIdGenerator

IdGenerator for java util UUID.

It extends the UuidV1RndIdGenerator so that it can generate rfc4122 compliant Type 1 UUIDs.

This generator produces real Type 1 UUIDs (best for sqlserver) - You should use this generator only, if you can guarantee, that mac addess is uniqe or specify 'ebean.uuidNodeId' in your config file.
