public class APFactoryH

extends java.lang.Object

implements APFactory

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