What is the use of namespacename::classname().function()

[My4th]

I am looking in some old code of someone who's gone. Why should one use
something like namespacename::classname().thefunction()? He repeatedly does
that.

The function is virtual and not static. If you create a temporary
namespacename::classname() class to call thefunction(), at least that is
what I understand of it, then would it not be more sense to make thefunction
static? What the use of making thefunction virtual if you already decide
which function you call, for the temp class you use?

Only if calling it on temporaries is the only useful way of calling it.

Again, it depends on wether the temporary is the only way the function could
ever be used.

ok! I am stuying this code before I can say whether or not its used in other
contekstes also.
