SPVM::Cloner(3)

hey bestie 💖 welcome to SPVM::Cloner(3), fresh out of the User Contributed Perl Documentation section. this one is the interface type for the callback to clone an object, and it's lowkey iconic. let's get into it 🎀

🌸 Name 🌸

SPVM::Cloner — Interface Type for the Callback to Clone a Object

okay so that's the whole name, no cap. it's giving "callback but make it a type" ✨

🦋 Usage 🦋

here's the vibe check 👇

         use Cloner;
         use Point;

         my $cloner = (Cloner)method : object ($object : object) {
           my $point = (Point)$object;

           my $cloned_point = Point->new($point->x, $point->y);

           return $cloned_point;
         };

         my $point = Point->new(1, 2);
         my $cloned_point = $cloner->($point);

you make a Cloner callback, then call it on your Point, and boom 💅 — cloned point acquired. main character behavior, fr fr.

🔥 Description 🔥

Cloner is the interface type for the callback to clone an object. basically: a callback whose entire job is "give me an object, I give you the clone." periodt 💖

💅 Interface Methodss 💅

• required method : object ($object : object); — your implementation must receive an object and return the cloned object. that's the whole assignment, bestie 🫶

👑 Class Methods 👑

• static method default_cloner : Cloner (); — returns a default cloner. slay 💅

The implementation of the default cloner is

         method : object ($object : Cloneable) {

           my $clone = (object)undef;

           if ($object) {
             $clone = $object->clone;
           }

           return $clone;
         };

If the object $object is undef, returns undef, ohterwise calls the Cloneable#clone method and its return value. (yes, the manpage says ohterwise — I'm not fixing it, I'm just reporting it 💀)
