org.eclipse.persistence.mappings.structures.ObjectArrayMapping
public class 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.
