Static Members

Static members are members of the class that will exist regardless of whether or not any objects of the class are created.
Once a static members has been created, they cannot be destroyed. Static members are also global, so all class objects have access to them, and their property will be the same across all of the objects.

To create a static member in Class++, you have to use the class.static(<accessSpecifier>, <name>, <property>) function.

local class = ClassPP.class

local Test = class "Test" {
    Public = {
        TestValue = 0
    }
}

Test.static("Public", "StaticTestValue", function(firstArgument)
    print(firstArgument) -- This will not point to any object, instead it will print whatever it is called with! In this case, it will print "Hi!".
end)

local newTest = Test.new()
newTest:StaticTestValue() -- This will error!

Test.StaticTestValue("Hi!") -- This will work fine!

You can also give properties that aren't functions. So to retrieve those properties, you can do class.<memberName>.property or class.<memberName>.p for short.

local class = ClassPP.class

local Test = class "Test" {
    Public = {
        TestValue = 0
    }
}

Test.static("Public", "StaticTestValue", 1)

print(Test.StaticTestValue.property) -- Prints "1"!
print(Test.StaticTestValue.p) -- Also prints "1"!
