public class FDNullFactoryH

extends java.lang.Object

implements FDNullFactory

This class holds the factory methods for the FDNull class. Users can use this class to create instances of FDNull objects with their desired parameters. A static keyword is used to instantiate an instance of FDNullFactoryH so that the static variable "factory" in this class will have access to the create methods. Users can also create instances of FDNullH directly using the constructors of the FDNull class. The primary reason of the creation of this class is to allow the FDNull class, which implements the FDNull interface to have constructors while being able to implement all the methods in the interface.
