Friend Access Specifier

Friend access specifier allows anyone defined in that access specifier to access the private members of a class.

Warning

Members of this access specifier will not be replicated to objects, rather, these members are stored in the class itself, and they can only be used to access the members in other access specifiers through objects.

local function getLicensePlate(object: any)
    print(object.License_Plate)
end

local class = ClassPP.class

local Car = class "Car" {
    Public = {
        Brand = "Lamborghini",
    },
    Private = {
        License_Plate = "XXXX"
    },
    Friend = {
        getLicensePlate
    }
}

local newCar = Car.new()
getLicensePlate(newCar)

In this example, we updated the previous class to include a function in the Friend access specifier, this function is now able to access the private members of this class.

Info

Aside from functions, Friend access specifier can include other classes as well. Classes can be saved by using their variables, or their names. You can put a string inside the Friend access specifier that has the class's name, and it will still work!
