Rose::...r::Null(3pm)

Okay bestie, welcome to the Rose::...r::Null(3pm) page from User Contributed Perl Documentation 💅 This one is all about Rose::DB::Object::ConventionManager::Null, and the vibe check is: it literally does nothing. Iconic, honestly.

💖 NAME 💖

Rose::DB::Object::ConventionManager::Null — a singleton convention manager that does nothing. Periodt 💀✨

🌸 SYNOPSIS 🌸

Here’s the synopsis, exact and untouched, bestie:

package My::Product;

use Rose::DB::Object;
our @ISA = qw(Rose::DB::Object);

# This really sets the convention manager to a
# Rose::DB::Object::ConventionManager::Null object
__PACKAGE__->meta->convention_manager(undef);
...

That undef is not a typo — it really sets the convention manager to a Rose::DB::Object::ConventionManager::Null object. Slay.

🦋 DESCRIPTION 🦋

Okay so Rose::DB::Object::ConventionManager::Null is a subclass of Rose::DB::Object::ConventionManager that does nothing. The way it commits to the bit: it overrides every method with no-ops that always return undef or an empty list, depending on calling context. It’s a singleton, too — one and only one, main character energy 👑.

Here’s when you’d use it: when a piece of metadata is missing, the convention manager is asked to provide it. This "null" convention manager class is useful if you do not want the convention manager to provide any information. In other words, use this convention manager class if you want to force all metadata to be explicitly specified. No cap — if you want every bit of metadata spelled out by you, this is the one 🔥.

See the Rose::DB::Object::ConventionManager documentation for more information on convention managers. Go read it, bestie, it’s giving essential context 📚✨.
