All Implemented Interfaces:

RelationalReference

public class AlphaNumericSequencerImpl

extends EntityImpl

This class generates sequential identifiers in a prescribed format.. The user of the classs can configure the starting number, prefix, suffix, and step. It is also possible to specify the width of the numeric component. The current sequence number is persisted and access to the counter is controlled so that uniqueness can be guaranteed across all users of a given sequencer. It is used to generate unique keys for entities such as accounts, users, and sessions.

 Primary Key = com.beasys.commerce.axiom.util.AlphaNumericSequencerPk
