public class ArrayMapping extends AbstractCompositeDirectCollectionMapping

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.
