Hi,
I wan't implement singleton pattern but I have compilation error :
using GLib;
>
> public class Singleton : Object
{
> static Singleton* _instance = null;
>
> private Singleton ()
> {
> }
>
> public static Singleton* instance
> {
> get
> {
> if (_instance == null)
> {
> _instance = new Singleton ();
> }
> return _instance;
> }
> }
>
> public static Singleton* get_instance ()
> {
> if (_instance == null)
> {
> _instance = new Singleton ();
> }
> return _instance;
> }
>
> public static int main (string[] args)
> {
> Singleton* s = null;
> s = Singleton.get_instance ();
> s = Singleton.instance; // line 35
> return 0;
> }
> }
>
And compilation command :
$ valac singleton.vala
> /home/gege2061/test/vala/singleton.vala:35.7-35.7: error: Assignment:
> Invalid callback assignment attempt
> Compilation failed: 1 error(s), 0 warning(s)
