AW: Size of a non numerical indexed table

["steffenj" <steffenj@...>]

hmmm, quick and dirty solution:

local count = 0
table.foreach(table, function(i, v)
	-- don't count numerical indices:
	if type(i) == "string" then
		count = count + 1
	end
end

but it's definetely better to use a metatable and count all the string
indizes when values are assigned to table indizes

i haven't used metatables so far but the basics are to check, on assignment,
wether the index is a string and wether the value is nil (delete index) or
not (new index) and based on that, update a counter in the table

i hope someone else can give an example...

Betreff: Size of a non numerical indexed table

Well, I think that the subject tells my question!

If it's a numerical indexed table, I can use
table.getn, but if the table is indexed by names, how
to get it's size?

Thanks!
