Scenes
Boss: Design a universal factory. Currently, products A and B can be produced, and C, D may be produced in the future... These products belong to the same product family.
You: Good boss, then use the abstract factory model
Program
Products will increase over time. These products have similar attributes. We can call them a product family. We use an abstract factory (that is, a universal factory that can produce the same product family) to solve this problem, so that our code can be Unlimited expansion
achieve
see:github
package main
import "fmt"
type Product string
type AbstractFactory interface {
createA() Product
createB() Product
}
type Factory struct {
}
func (*Factory) createA() Product {
fmt.Println("生产A")
return Product("A")
}
func (*Factory) createB() Product {
fmt.Println("生产B")
return Product("B")
}
func main() {
fmt.Println("从万能工厂那生产所有产品")
fmt.Println("好的，老板")
var f AbstractFactory
f = &Factory{
}
f.createA()
f.createB()
}
