Is a static method sufficient to call it factory?

Hi everyone,

I've just a doubt...

Talking about factories why someone propose the way

Factory.getInstance().createClass(aType);

instead of simply

Factory.createClass(aType);

That is,
why the singleton?

In the end, is a class with a static method eligible to be an use of a
factory method pattern? It doesn't resemble the structure of the GOF
pattern, since it doesn't use subclassing...

Suppose that what createClass() method does is to instantiate a
concrete class
based on the parameter.


cheers,
Francesco
