All Implemented Interfaces:

public class ObjectArrayMapping
extends AbstractCompositeCollectionMapping

Purpose: In an object-relational data model, structures can contain "Arrays" or collections of other data-types. In Oracle 8i, a Varray is typically used to represent a collection of primitive data or aggregate structures. These arrays are stored with their parent structure in the same table.

ArrayMapping is used to map a collection of primitive data

ObjectArrayMapping is used to map a collection of Oracle data-type

NOTE: Only Oracle8i supports Varray type.

Since:

TOPLink/Java 3.0
