Grouping functions as component

[manaus]

Hello, 
I read someone sometimes uses to group functions semantically in a component.
You instantiate it and use its functions. But well looks to me that it is not the proper use of a component.
You should instantiate it passing a value, so the new value inherits all the functions of the component.
Am I right?
I now have a component with 20 query functions, and is starting to make me feel dizzy.
Thanks!

Hi Max, 

The idea of components with similar functions makes sense -- you can make libraries of functions that are often used together, for example maths functions, or database operations, etc.  It seems like a perfectly good way to use components.

I didn't understand this bit: "You should instantiate it passing a value"... Can you give an example?

Thanks James,
well what I mean is that, for instance

m = new cfc.EmailClass("myad...@domain.etc");
m.sendHello();
m.deleteFromDb();

And so on
In my case I'm having a component such as

d = new cfc.Queries();
d.findAllLivingInChina();
d.findCityId("Berlin");

d, in this case, has no value. So why using it? :)
Sorry sounds like pre-primer questions :)

Ah, I see what you mean.  Yes, you're quite right.  It does seem like a waste, but CFML doesn't support static classes.  In other languages you can do exactly what you are saying... but in CF you have to instantiate the class.
