All Implemented Interfaces:

Externalizable, ItemBuilder, Serializable

public class ObjectReferenceItemBuilder

extends AttributeItemBuilder

implements Externalizable

This class provides the functionality for building an object reference from a result set.

The internal implementation uses the get methods of the ResultSet class. The Object Reference can be the OID of the object itself or a foreign key OID.
