org.eclipse.persistence.mappings.structures.ObjectArrayMapping

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. @author King (Yaoping) Wang @since TOPLink/Java 3.0 @see ArrayMapping

     * Process the ArrayMapping or ObjectArrayMapping.
