Oh, you are right. I didn't expected this. I though `self' would make it
an instance variable. Now I have to rephrase my question: Why is
`self.count' a class variable in the following example while `self.text'
is a member variable?
Display = {}
Display.count = 0
function Display:new ()
local me = {}
setmetatable(me, self)
self.__index = self
self.count = self.count + 1
return me
end
function Display:getCount ()
return self.count
end
function Display:setText (text)
self.text = text
end
function Display:getText ()
return self.text
end
dis1 = Display:new()
dis2 = Display:new()
print(dis1:getCount(), dis2:getCount())
dis1:setText('foo')
dis2:setText('bar')
print(dis1:getText(), dis2:getText())
