Examples of ChangeNumberGenerator

org.nasutekds.server.replication.common.ChangeNumberGenerator
This class defines a structure that is used for storing the last change numbers generated on this server or received from other servers and generating new changenumbers that are guaranteed to be larger than all the previously seen or generated change numbers.
