UnaryTableSequence (EclipseLink 2.6.1, API Reference)

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:

java.io.Serializable, java.lang.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.
