I guess you describe the "Factory method" pattern.
def :
Define an interface for creating an object, but let subclasses decide 
which class to instantiate. Factory Method lets a class defer 
instantiation to subclasses.


My snippet is based on the "Abstract Factory" pattern. Also called 
"Factory design" pattern or simply "Factory" pattern . Indeed a bit 
confusing.
def :
Provide an interface for creating families of related or dependent 
objects without specifying their concrete classes.
