On Jon's site he has thisvery elegantly designed singleton in C# that looks like this:
public sealed class Singleton
{
Singleton()
{
}
public static Singleton Instance
{
get
{
return Nested.instance;
}
}
class Nested
{
// Explicit static constructor to tell C# compiler
// not to mark type as beforefieldinit
static Nested()
{
}
internal static readonly Singleton instance = new Singleton();
}
}
I was wondering how one would code the equivalent in C++? I have this but I am not sure if it actually has the same functionality as the one from Jon. (BTW this is just a Friday exercise, not needed for anything particular).
class Nested;
class Singleton
{
public:
Singleton() {;}
static Singleton& Instance() { return Nested::instance(); }
class Nested
{
public:
Nested() {;}
static Singleton& instance() { static Singleton inst; return inst; }
};
};
...
Singleton S = Singleton::Instance();
I'd think people had something to do on the weekends other than more work– Matthew Scharley Oct 30 '09 at 08:58
