In proper encapsulation, you should not "see" what is happening upon instanciation. To rely on a class's lack of a constructor is breaking this form. The designed of the class my have in mind to add formal state initialization in the constructor at a later date. Your "contract" with the class is only that you can use the methods as they are currently designed.

If you desire to use the functionality of that method without the class overhead, maybe it best for you to include that method in your existing "client" class (of course this is just "copy and paste" coding and is considered an anti-pattern of of software design.
