MooseX...::Fast(3pm)

💖 MooseX::Emulate::Class::Accessor::Fast — the manual page, but make it cute 💖

perl v5.36.0 · User Contributed Perl Documentation · MooseX...::Fast(3pm)

okay bestie, sit down, hydrate, because we're doing MooseX::Emulate::Class::Accessor::Fast and honestly? it's giving glow-up arc. 🦋

---

✨ NAME ✨

MooseX::Emulate::Class::Accessor::Fast — it emulates Class::Accessor::Fast behavior using Moose attributes. that's the whole vibe. no cap. 💅

---

🌸 SYNOPSYS 🌸

(yes the section is literally spelled "SYNOPSYS", we respect the original's choices 🎀)

package MyClass;
use Moose;

with 'MooseX::Emulate::Class::Accessor::Fast';

#fields with readers and writers
__PACKAGE__->mk_accessors(qw/field1 field2/);
#fields with readers only
__PACKAGE__->mk_ro_accessors(qw/field3 field4/);
#fields with writers only
__PACKAGE__->mk_wo_accessors(qw/field5 field6/);

look at that. three lines and you have a whole personality. 😭

💜 DESCRIPTION 💜

so this module is out here attempting to emulate the behavior of Class::Accessor::Fast as accurately as possible using the Moose attribute system. the public API of Class::Accessor::Fast is wholly supported — like, all of it — but the private methods are NOT. 🙈

and if you're only using the public methods (which, bestie, you should be, that's the whole point), migration is genuinely just switching your use base line to a with line. that's it. that's the glow-up. iconic. 👑

ngl, the author says they've attempted to emulate the behavior of Class::Accessor::Fast as closely as possible — but bugs may still be lurking in edge-cases. so like. edge cases. be aware. 💀

🦋 BEHAVIOR 🦋

there's simple documentation right here for your convenience, but for the thorough stuff you're gonna want to go read Class::Accessor::Fast and Class::Accessor. go on, we'll wait. 🫶

🔍 A note about introspection 🔍

please note: at this time, the is flag attribute is not being set. 😭

so if you're trying to figure out the reader and writer methods using introspection in later versions of Class::MOP ( > 0.38 ), please use the get_read_method and get_write_method methods in Class::MOP::Attribute. example time, slay:

# with Class::MOP <= 0.38
my $attr = $self->meta->find_attribute_by_name($field_name);
my $reader_method = $attr->reader || $attr->accessor;
my $writer_method = $attr->writer || $attr->accessor;

# with Class::MOP > 0.38
my $attr = $self->meta->find_attribute_by_name($field_name);
my $reader_method = $attr->get_read_method;
my $writer_method = $attr->get_write_method;

👑 METHODS 👑

⭐ BUILD $self %args

Change the default Moose class building to emulate the behavior of C::A::F and store arguments in the instance hashref. periodt. 💅

⭐ mk_accessors @field_names

Create read-write accessors. An attribute named $field_name will be created. the name of the reader and writer methods will be determined by the return value of accessor_name_for and mutator_name_for, which by default return the name passed unchanged. 🎀

and if the accessor and mutator names are equal, the accessor attribute will be passed to Moose; otherwise the reader and writer attributes will be passed. please see Class::MOP::Attribute for more information. iykyk. 🌸

⭐ mk_ro_accessors @field_names

Create read-only accessors.

⭐ mk_ro_accessors @field_names

Create write-only accessors.

okay so — this is literally what the page says. the second one is printed as mk_ro_accessors @field_names and its description says "Create write-only accessors." the synopsis up top uses mk_wo_accessors for writer-only fields. we are not editing the sacred text, we're just showing you exactly what it says. 💀

⭐ follow_best_practices

Preface readers with 'get_' and writers with 'set_'. See original Class::Accessor documentation for more information. 🎀

⭐ mutator_name_for

⭐ accessor_name_for

See original Class::Accessor documentation for more information.

⭐ set

See original Class::Accessor documentation for more information.

⭐ get

See original Class::Accessor documentation for more information.

⭐ meta

See Moose::Meta::Class.
