All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, ContainerMapping

public class NestedTableMapping
extends CollectionMapping

Purpose: Nested tables are similar to VARRAYs except internally they store their information in a separate table from their parent structure's table. The advantage of nested tables is that they support querying and joining much better than varrays that are inlined into the parent table. A nested table is typically used to represent a one-to-many or many-to-many relationship of references to another independent structure. TopLink supports storing a nested table of values into a single field.

NOTE: Only Oracle8i supports nested tables type.

Since:

TOPLink/Java 2.5
