Class AbstractEntityReference<A extends Entity,B extends Entity>

java.lang.Object
  com.jgoodies.binding.beans.Model
      de.schwarzrot.data.support.AbstractEntity
          de.schwarzrot.data.support.AbstractEntityReference<A,B>

Type Parameters:

A - the master Entity

B - the related Entity

All Implemented Interfaces:

com.jgoodies.binding.beans.Observable, Entity, EntityReference<A,B>, Serializable, Comparable<Entity>

Direct Known Subclasses:

AbstractWeightedEntityReference

public abstract class AbstractEntityReference<A extends Entity,B extends Entity>
extends AbstractEntity
implements EntityReference<A,B>

implements a base class for anonymous references between different Entity. The referenceA is silently considered the master and referenceB is silently considered the related target.

Method Detail

getReferenceA

public final A getReferenceA()

Specified by:

getReferenceA in interface EntityReference<A extends Entity,B extends Entity>

getReferenceB

public final B getReferenceB()

Specified by:

getReferenceB in interface EntityReference<A extends Entity,B extends Entity>

getUniqColumnNames

public List<String> getUniqColumnNames()

Description copied from interface: Entity

returns a list of property names, which serve to detect a uniq instance without the usage of the primary key. In database context this list is used to decide, whether a save operation needs an update or an insert.

Specified by:

getUniqColumnNames in interface Entity

Overrides:

getUniqColumnNames in class AbstractEntity

Returns:

a list of property names

setReferenceA

public final void setReferenceA(A referenceA)

Specified by:

setReferenceA in interface EntityReference<A extends Entity,B extends Entity>

setReferenceB

public final void setReferenceB(B referenceB)

Specified by:

setReferenceB in interface EntityReference<A extends Entity,B extends Entity>
