Is it possible to detect armor (and to a lesser extent, weapon) types with triggers?

I'll just make things simple.

Is there any possible way to detect a unit's armor type through triggers? I'm creating a few different spells (through the object editor, but I plan to make some trigger-based) and I want them to have different effects, depending on the type of armor the target unit has. Is this at all possible through triggers, or am I going to need to use JASS? Or should I just come to a conclusion that it's not possible and give up right now?

EDIT: Meh, oh well. Thanks for the help, anyway. ^_^;

No, there isn't.

In relation to the original post, is there a function that would give you the ammount of armour a unit has (it would be a real function, I suppose)? I know it isn't in GUI, but maybe it exists nevertheless and can be used with custom text? Just asking if there's a simpler method than what I currently use, which is checking the unit's agility and the bonus armour items the unit has.

I'm almost positive there isnt, I just searched for 'unit' with that jedit thing I keep talking about and couldnt find a single good function or constant in the entire blizzard.j and common.j.
