Examples of AggregateObjectMapping

oracle.toplink.essentials.mappings.AggregateObjectMapping

Purpose:Two objects can be considered to be related by aggregation if there is a strict 1:1 relationship between the objects. This means that if the source (parent) object exists, then the target (child or owned) object must exist. In TopLink, it also means the data for the owned object is in the same table as the parent. @author Sati @since TOPLink/Java 1.0

Purpose:Two objects can be considered to be related by aggregation if there is a strict 1:1 relationship between the objects. This means that the target (child or owned) object cannot exist without the source (parent) object. In TopLink, it also means the data for the owned object is stored in the same table as the parent. @author Sati @since TOPLink/Java 1.0
