"Cold River Snow" Go Implementation Template Method mode

Template Pattern

The template method design pattern allows the different parts of the object to be abstracted, executing the same logic in the same piece of code, and increasing extensibility. In the go language, implementations are implemented by the underlying object, and the behavior is controlled by the top-level method. Implement

Package template

Import "FMT"

type Tmpl interface{
    dosomething ()
    doanything ()
}

type Tmpla struct{

}

func (this *tmpla) dosomething () {
    fmt. Println ("tmpla.dosomething")
}

func (this *tmpla) doanything () {
    fmt. Println ("tmpla.doanything")
}

type TMPLB struct{

}

func (this *tmplb) dosomething () {
    fmt. Println ("tmplb.dosomething")
}

func (this *tmplb) doanything () {
    fmt. Println ("tmplb.doanything")
}

func Operate (Tmpl tmpl) {
    Tmpl. DoSomething ()
    Tmpl. Doanything ()
}

Use

Package main

Import (
    "Projects/designpatternsbygo/behavioralpatterns/template"
)

func main () {
    A: = template. tmpla{}
    B: = template. tmplb{}
    template. Operate (&a)
    template. Operate (&b)

}
