Hey,
having parameters in a singleton is against the pattern in general. Imagine a
simple scenario:
// some place
var a = Singleton.getInstance(1,2); // returns a configured singleton with 1
and 2
// ...
// some other place
var b = Singleton.getInstance(2,1); // what should it return? A new instance
configured with the new parameter or the old one and ignore the parameter?
You see, it is some kind of a problem here because you would either have more
than one instance or ignore the second set of parameters.
If you think that one of the both suggested ways is exactly what you need, you
can still configure your class the way you want with a own getInstance method.
But from a software development point of view, I would really not recommend
that.
Regards,
Martin
