Class ObjectField

java.lang.Object

com.nt.udc.ndk.node.DCField

com.nt.udc.ndk.node.ObjectField

All Implemented Interfaces:

Externalizable, Serializable, Cloneable

public class ObjectField
extends DCField
implements Externalizable

The class ObjectField. It is a sub-class of DCField. It deal with the OBJECT attribute. NOTE - VERY IMPORTANT This is a class will be used to contain an object of any class to be written into a NAR as a NAR OBJECT primitive. The object which is stored in this class (via the setObject method or the constructor that takes an Object as an input parameter) must be Externalizable.
