Defining the armor type

[Torhal]

Here's code for determining all of the item classes and their associated subclasses:

do
	COMPILED_ITEM_CLASSES = {}
	local classIndex = 0
	local className = _G.GetItemClassInfo(classIndex)

	while className and className ~= "" do
		COMPILED_ITEM_CLASSES[classIndex] = {
			name = className,
			subClasses = {},
		}

		local subClassIndex = 0
		local subClassName = _G.GetItemSubClassInfo(classIndex, subClassIndex)

		while subClassName and subClassName ~= "" do
			COMPILED_ITEM_CLASSES[classIndex].subClasses[subClassIndex] = subClassName

			subClassIndex = subClassIndex + 1
			subClassName = _G.GetItemSubClassInfo(classIndex, subClassIndex)
		end

		classIndex = classIndex + 1
		className = _G.GetItemClassInfo(classIndex)
	end
end

You can then look at the table (it's globally declared) to see what's what. The starting index of 0 rather than 1 is intentional - they're actually used by Blizzard.
