✨ NAME ✨

okay so bestie, welcome to the MakeMe...gleton(3pm) page 💅 — manual name folded in near the top, from the User Contributed Perl Documentation section. We're doing Perl singleton lore today. 🦋

Class::MakeMethods::Emulator::Singleton — literally here to emulate Class::Singleton. That's the name, no cap. 🎀

---

✨ SYNOPSIS ✨

Like, the whole point is: call it once, get an instance; call it again, get the same instance. The code is doing main character energy:

use Class::MakeMethods::Emulator::Singleton;

# returns a new instance
my $one = Class::MakeMethods::Emulator::Singleton->instance();

# returns same instance
my $two = Class::MakeMethods::Emulator::Singleton->instance();

So $one gets the new instance, and $two gets the same instance — that's the singleton slay. 💖

---

✨ COMPATIBILITY ✨

okay so this module is emulating the functionality of Class::Singleton, using Class::MakeMethods to generate similar methods. Iconic, fr fr. You may use it directly, exactly like the SYNOPSIS above shows. ✨

You may also call:

use Class::MakeMethods::Emulator::Singleton '-take_namespace';

That aliases the Class::Singleton namespace to this package, and subsequent calls to the original package will be transparently handled by this emulator. iykyk. To remove the emulation aliasing, call:

use Class::MakeMethods::Emulator::Singleton '-release_namespace';

Caution: this affects all subsequent uses of Class::Singleton in your program, including those in other modules, and might cause unexpected effects. So, like, be aware, bestie — this is highkey a whole global-namespace vibe shift. 😭

---

✨ DESCRIPTION ✨

A Singleton describes an object class that can have only one instance in any system. Literally one. An example of a Singleton might be a print spooler or a system registry. 🖨️

This module implements a Singleton class from which other classes can be derived. By itself, the Class::Singleton module does very little other than manage the instantiation of a single object. ngl, that's its whole thing, and honestly, same. In deriving a class from Class::Singleton, your module will inherit the Singleton instantiation method and can implement whatever specific functionality is required. Periodt. 💅
