Class UnaryTableSequence

java.lang.Object

org.eclipse.persistence.sequencing.Sequence

org.eclipse.persistence.sequencing.StandardSequence

org.eclipse.persistence.sequencing.QuerySequence

org.eclipse.persistence.sequencing.UnaryTableSequence

All Implemented Interfaces:

Serializable, Cloneable

public class UnaryTableSequence
extends QuerySequence

Purpose: Defines sequencing through using a singleton sequence table.

Description This is similar to the TableSequence but the sequence table only stores a single row defining a single sequence.
