UnaryTableSequenceDefinition (EclipseLink 2.6.3, API Reference)

java.lang.Object
- org.eclipse.persistence.tools.schemaframework.DatabaseObjectDefinition
- - org.eclipse.persistence.tools.schemaframework.SequenceDefinition
  - - org.eclipse.persistence.tools.schemaframework.TableSequenceDefinition

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable
```
public class UnaryTableSequenceDefinition
extends TableSequenceDefinition
```
Purpose: Creates / drops an unary sequence table: the name of the table is sequence name; its only field is named unarySequenceCounterFieldName
