I use this method for pretty much all my libtary code now. My observation
the overhead of instanciation is negligable when compared to calling the
command itself, which is pretty slow. Although Brad is the one to answer
questions on speed. In fact, one of the great advantages of this method is
that you can minimise the number of calls to commands by creating them as
methods of an object itself, creating the object, for example, outside of
the loop, keeping the method calls inside.
If you're really concerned, though, why not do some timing tests.
As for Python classes as commands, I also use this a lot to pull in the kind
of tools not available from Jscript or VB. In particular I prefer the file
handling tools but there's also socket handling, mail, filetype, XML, SQL
...... It opens up a whole bunch of possibilities. It allows me to carry on
working with my core scripting tools, which are Jscript, but with increased
fucntionality.
An yeah, I know Bernard. I'll get on the case as soon as I clear up what I'm
doing right now. I should keep my mouth shut until I can deliver. ;)
