go设计模式之抽象工厂

package main

import "fmt"

type IProduct interface {
	ShowBrand()
}

type IPhone struct {
}

func (p *IPhone) ShowBrand() {
	fmt.Println("我是苹果手机")
}

type Mac struct {
}

func (pc *Mac) ShowBrand() {
	fmt.Println("我是苹果电脑")
}

type Factory interface {
	CreatePhone() IPhone
	CreatePc() Mac
}


// 苹果工厂
type IFactory struct {
}

func (F *IFactory) CreatePhone() IProduct {
	return &IPhone{}
}

func (F *IFactory) CreatePc() IProduct {
	return &Mac{}
}

func main() {
	var  factory = &IFactory{}

    phone := factory.CreatePhone()
    phone.ShowBrand()

    pc := factory.CreatePc()
    pc.ShowBrand()
}
