process

Purpose

This framework has the purpose of simplifying the execution of processes and the evaluation of errors

Description

this framework allows to define a process as a set of steps that are executed until one of them fails. If one step fails the rest of the steps are not invoked

Example

This Code (without using process)

func main() {
    person := &Person{Name: "Name", Age: 20}
    var err error
    if person, err = validate(person); err != nil {
        fmt.Println(err)
        return
    }
    if person, err = create(person); err != nil {
        fmt.Println(err)
        return
    }
    if person, err = audit(person); err != nil {
        fmt.Println(err)
        return
    }
    //Ok!!
    fmt.Println(person)
}

Can be replaced by this

func main() {
    //Create Process
    proc := createProcess()
    //Init process
    person := &Person{Name: "Name", Age: 20}
    //Execute the process
    //RullAll execute Validate,Create and Audit
    if proc.Start(person).RunAll().Error() != nil {
        //errors?
        fmt.Println(proc.Error())
    } else {
        //Ok!!!
        person := proc.Result().(*Person)
        fmt.Println(person)
    }
}
