Class PropertyOne2Many<T extends net.tangly.bus.core.HasOid,​R extends net.tangly.bus.core.HasOid>

java.lang.Object
net.tangly.orm.imp.PropertyOne2Many<T,​R>
Type Parameters:
T - class owning the propertyBy
R - Class referenced by the propertyBy
All Implemented Interfaces:
Property<T>, Relation<T,​R>
public class PropertyOne2Many<T extends net.tangly.bus.core.HasOid,​R extends net.tangly.bus.core.HasOid>
extends java.lang.Object
implements Property<T>, Relation<T,​R>
Models a propertyBy with managed objects as values and supporting multiple objects. When the propertyBy is read we retrieve all instances which foreign key format is equal to the unique object identifier oid of the owner of the propertyBy. When writing the foreign key propertyBy with the unique object identifier oid of the owner of the propertyBy and when persist all the objects.
