lua实现面向对象

实现类的定义

function people( name)

    local  self = {}

    local  function init( ... )
        self.name=name
    end 

    self.sayHi=function ( ... )
        print("hello"..self.name)
    end

    init()
    return self
end

实现类的继承

function Man( name)
    self=people(name)

    self.sayHello=function (  )
        print("hi"..self.name)
    end
    return self
end

local  ex = Man("李四")
ex.sayHello()
