I can call the functions with mytab.func1(), but I would like to use a reference to the table itself (like the self parameter on Python classes):
mytab = {
func1 = function(self, ?) do something end
func2 = function(self, ?) do something other
}
and self should be point to mytab. How can I do this?
Your solution using self works fine. Just call the function with mytab:func1().
The short example works, but on my full example it does not. I have defined:
local myClassDef = {
__instancedata = {},
__metadata = {},
constructor = function(…) end
}
myClass.__metadata = {
__call = function(self, …) self:constructor(self.__instancedata, …) return self end,
__newindex = function(self, key, value) self.__instancedata[key] = value,
__index = loClassDef.__instancedata
}
local myClass = setmetatable( myClassDef, myClassDef,__metadata
function myClass:constructor( self, id )
self.id = id
end
function myClass:test( self )
print(self)
end
x = myClass( 123 )
x.test() -- shows nil
I try to define my own OOP structure, I have take a look to loop, etc. I would like to push the table itself to each defined method
Tanks a lot for help
