General information

Base class implementation for Lua

Installation

You can:

• clone the repository:

git clone https://github.com/a1div0/lua-object.git

• install the lua-object module using tarantoolctl:

tarantoolctl rocks install https://raw.githubusercontent.com/a1div0/lua-object/main/lua-object-1.0.3-1.rockspec

Usage

Create a child class

local Object = require('lua-object')
local NewClass = Object:extend()
local NewClassChild = NewClass:extend()

Creates an instance of the class

local obj = NewClass:new(a, b, c...)

Declare constructor

function NewClass:initialize(a, b, c...)
    ---
end

initialize - is key word

Declare method

function NewClass:method1(a, b, c...)
    ---
end

Call parent method

function NewClassChild:method1(a, b, c...)
    ---
    NewClass.method1(self, a, b, c...)
    ---
end

Checks if an instance of an object belongs to this class or to one of the parents of this class

if obj.myInstance(NewClass) then
    ---
end 

An example of using the module

local Object = require('lua-object')

local BaseTable = Object:extend()
function BaseTable:myFunction1(arg1, arg2, arg3)
    --
    -- ...
    --
end

local tableA = BaseTable:new()

if tableA:isInstance(Object) then
    tableA:myFunction1(1, 2, 3)
end
