Golang : Implement getters and setters
Because Golang does not provide automatic getters and setters, Go programmers will have to implement the getters and setters themselves. This is a quick tutorial on how to set and get identifiers value in a struct.
package main
import (
"fmt"
)
type Person struct {
Name string // exported identifier
email string // un-exported identifier... need Set and Get methods for help
}
func (p *Person) SetEmail(email string) {
p.email = email
}
func (p Person) GetEmail() string {
return p.email
}
func main() {
employee := Person{}
//employee := new(Person) // new object
fmt.Println(employee)
// set data to private variable via SetEmail method
employee.SetEmail("happyworker@xmail.com")
employee.Name = "Adam"
fmt.Println(employee)
// Retrieve data from private variables via GetEmail method
fmt.Println(employee.GetEmail())
fmt.Println(employee.Name)
}
Output :
{ }
{Adam happyworker@xmail.com}
happyworker@xmail.com
Adam
