EnvironmentFactory

public class EnvironmentFactory extends Object
provides a implementation of factory. Users can extend this class and implement required methods and set their class in environment variable ENVIRONMENT_FACTORY_CLASS. The statis create method in this class reads the variable and instantiates the class. Note that the implemented factory needs a no arg constructor
