--Table当Map使用
var={name="a",sex=1,age=18}

for key,var in pairs(var) do
print(key,var)
end

--Table当数组使用
arr={1,1,2,3,"hello"}

table.insert(arr,1,"world")
print(table.maxn(arr))

for key,var in pairs(arr) do
print(key,var)
end

--复制表的方式面向对象
People={}

function People.sayHi()
print("hi")
end

People.sayBey=function()
print("bye")
end

function clone(tab)
ins={}
for key,var in pairs(tab) do
ins[key]=var
end
return ins
end

function People.new(name)
ins=clone(People)
ins.name=name
return ins
end

People.sayBey=function(self)
print("bye"..self.name)
end

p=People.new("Hel")
p.sayHi()
print(p.name)

--下面两句等价
p.sayBey(p)
p:sayBey()

--复制表的方式继承
function copy(dist,tab)
for key,var in pairs(tab) do
dist[key]=var
end
return dist
end

Man={}
Man.new=function(name)
local self=People.new(name)
copy(self,Man)
return self
end

Man.sayHello=function()
print("Man sya hello")
end

local m=Man.new("Lisi")
m.sayHello()

m:sayBey()

--函数闭包的方式面向对象
function People(name)
local self={}

local function init()
self.name=name
end

self.sayHi=function()
print("Hi")
end

init()
return self
end

local p=People("gg")
p.sayHi()

--函数闭包的方式继承
function Man(name)
local self=People(name)

local function init()

end

self.sayMan=function()
print("Man say"..self.name)
end

return self
end

local m=Man("g")
m.sayMan()
m.sayHi()
