Subject: Re: Accesing the name of an instance from within an method


Well here comes the big picture. I have a class contains some data and
amongst other things can generate graphs. What I would like to do is to
place these graphs in a bunch of files which have unique names (otherwise I
end up with always the last graph). Since only the variable (and the data)
are different amongst the instances I wonder how I could give them meaning
full names like "20070131 var1 XY.jpg" "20070131 var1 Both.jpg " etc. 

Now I did think about giving the var as an option while creating the
instance, but that doesn't help since it is perfectly possible in the code
that variable from which the instance is referenced is changed.

Now I come to think of it I could try to overload the = operater to let some
internal variable be changed when the reference is changed but then I still
need the name of the variable.

Kind regards
Gerald Ebberink

I'm going to invoke the "What are you trying to do?" rule.

If you give this group the bigger picture of what you are trying to  
accomplish
I'm sure we'll give you any number of options other than "you can't  
do that in Ruby".
