Private State

Each instance receives a __private table during construction. Use it for state that should not be part of the public API.

local Account = Class({
    init = function(self)
        self.__private.balance = 0
    end,

    deposit = function(self, amount)
        self.__private.balance = self.__private.balance + amount
    end,
})

Accessors

Class:accessor creates Get<Name> and Set<Name> methods backed by __private.

local Account = Class({
    init = function(self)
        Class:accessor(self, "balance", "Balance", 0)
        self:SetBalance(0)
    end,
})

local account = Account()
account:SetBalance(100)
print(account:GetBalance())

When a setter receives nil, it falls back to the default value passed to Class:accessor.
