Example
With methods in golang you can do method "chaining" passing pointer to method and returning pointer to the same struct like this:
package main
import (
"fmt"
)
type Employee struct {
Name string
Age int
Rank int
}
func (empl *Employee) Promote() *Employee {
fmt.Printf("Promoting %s\n", empl.Name)
empl.Rank++
return empl
}
func (empl *Employee) SetName(name string) *Employee {
fmt.Printf("Set name of new Employee to %s\n", name)
empl.Name = name
return empl
}
func main() {
worker := new(Employee)
worker.Rank = 1
worker.SetName("Bob").Promote()
fmt.Printf("Here we have %s with rank %d\n", worker.Name, worker.Rank)
}
Output:
Set name of new Employee to Bob
Promoting Bob
Here we have Bob with rank 2
