📝 NAME

Class::MOP::Method::Accessor - Method Meta Object for accessors

🚀 Quick Reference

Use Case	Command	Description
📖 Create a reader accessor	Class::MOP::Method::Accessor->new(attribute => $attr, accessor_type => 'reader')	Generate a read-only accessor for an attribute
✏️ Create a writer accessor	... accessor_type => 'writer'	Generate a write-only accessor
🔄 Create a read/write accessor	... accessor_type => 'accessor'	Generate a combined reader/writer
❓ Create a predicate	... accessor_type => 'predicate'	Generate a boolean check for attribute existence
🧹 Create a clearer	... accessor_type => 'clearer'	Generate a method to clear attribute value
🏷️ Check accessor type	$metamethod->accessor_type	Get the type of accessor ('reader', 'writer', etc.)
🔧 Check if inlined	$metamethod->is_inline	Returns boolean if method is inlined
📦 Get associated attribute	$metamethod->associated_attribute	Retrieve the Class::MOP::Attribute object
⚡ Execute the generated method	$metamethod->body->execute($instance)	Call the accessor method on an instance

💻 SYNOPSIS

use Class::MOP::Method::Accessor;

my $reader = Class::MOP::Method::Accessor->new(
    attribute     => $attribute,
    is_inline     => 1,
    accessor_type => 'reader',
);

$reader->body->execute($instance); # call the reader method

📖 DESCRIPTION

This is a subclass of Class::MOP::Method which is used by Class::MOP::Attribute to generate accessor code. It handles generation of readers, writers, predicates and clearers. For each type of method, it can either create a subroutine reference, or actually inline code by generating a string and eval'ing it.

🔧 METHODS

• Class::MOP::Method::Accessor->new(%options) — This returns a new Class::MOP::Method::Accessor based on the %options provided.
  • 📦 attribute — This is the Class::MOP::Attribute for which accessors are being generated. This option is required.
  • 🏷️ accessor_type — This is a string which should be one of reader, writer, accessor, predicate, or clearer. This is the type of method being generated. This option is required.
  • 🔧 is_inline — This indicates whether or not the accessor should be inlined. This defaults to false.
  • 📛 name — The method name (without a package name). This is required.
  • 📦 package_name — The package name for the method. This is required.
• $metamethod->accessor_type — Returns the accessor type which was passed to new.
• $metamethod->is_inline — Returns a boolean indicating whether or not the accessor is inlined.
• $metamethod->associated_attribute — This returns the Class::MOP::Attribute object which was passed to new.
• $metamethod->body — The method itself is generated when the accessor object is constructed.
