- org.hrorm.ParentColumnImpl<CHILD,PARENT,CHILDBUILDER,PARENTBUILDER>

Type Parameters:

CHILD - The child entity type

PARENT - The parent entity type

CHILDBUILDER - The class used to construct new CHILD instances

PARENTBUILDER - The class used to construct new PARENT instances

All Implemented Interfaces:

Column<Long,Long,CHILD,CHILDBUILDER>, ParentColumn<CHILD,PARENT,CHILDBUILDER,PARENTBUILDER>
```
public class ParentColumnImpl<CHILD,PARENT,CHILDBUILDER,PARENTBUILDER>
extends Object
