IndirectPrimaryKey (hrorm 0.10.0 API)

java.lang.Object
- org.hrorm.IndirectPrimaryKey<ENTITY,BUILDER>

Type Parameters:

ENTITY - The type of the class being persisted.

BUILDER - The type of the class that can construct new ENTITY instances.

All Implemented Interfaces:

Column<ENTITY,BUILDER>, PrimaryKey<ENTITY,BUILDER>
```
public class IndirectPrimaryKey<ENTITY,BUILDER>
extends Object
implements PrimaryKey<ENTITY,BUILDER>
```
Primary key for an entity whose construction is indirect, i.e. the entity is immutable and without setters.
Most users of hrorm will have no need to directly use this.
