-- Module class
-- Represents module.
-- The following fields are stored:
--    {i} = list of objects in the module.
classModule = {
    classtype = 'module'
}
classModule.__index = classModule
setmetatable(classModule,classContainer)

-- register module
function classModule:register (pre)
    pre = pre or ''
    push(self)
    output(pre..'tolua_module(tolua_S,"'..self.name..'",',self:hasvar(),');')
    output(pre..'tolua_beginmodule(tolua_S,"'..self.name..'");')
    local i=1
    while self[i] do
        self[i]:register(pre..' ')
        i = i+1
    end
    output(pre..'tolua_endmodule(tolua_S);')
    pop()
end

-- Print method
function classModule:print (ident,close)
    print(ident.."Module{")
    print(ident.." name = '"..self.name.."';")
    local i=1
    while self[i] do
        self[i]:print(ident.." ",",")
        i = i+1
    end
    print(ident.."}"..close)
end

-- Internal constructor
function _Module (t)
    setmetatable(t,classModule)
    append(t)
    return t
end

-- Constructor
-- Expects two string representing the module name and body.
function Module (n,b)
    local t = _Module(_Container{name=n})
    push(t)
    t:parse(strsub(b,2,strlen(b)-1)) -- eliminate braces
    pop()
    return t
end
