🚀 Quick Reference

Use Case	Command	Description
Create Overload Object	Class::MOP::Overload->new(%options)	Creates a new overload meta object.
Get Overloaded Operator	$meta->get_overloaded_operator('+')	Returns a Class::MOP::Overload object for the given operator.
Check Method Name	$overload->has_method_name	Returns true if a method name is defined.

🔰 SYNOPSIS

my $meta     = Class->meta;
my $overload = $meta->get_overloaded_operator('+');

if ( $overload->has_method_name ) {
    print 'Method for + is ', $overload->method_name, "\n";
}
else {
    print 'Overloading for + is implemented by ',
        $overload->coderef_name, " sub\n";
}

📝 DESCRIPTION

This class provides meta information for overloading in classes and roles.

🧬 INHERITANCE

Class::MOP::Overload is a subclass of Class::MOP::Object.

⚙️ METHODS

📇 Class::MOP::Overload->new(%options)

This method creates a new Class::MOP::Overload object. It accepts a number of options:

• operator 🎛️ — This is a string that matches an operator known by the overload module, such as "" or "+". This is required.
• method_name 📛 — The name of the method which implements the overloading. Note that this does not need to actually correspond to a real method, since it's okay to declare a not-yet-implemented overloading. Either this or the coderef option must be passed.
• method 📦 — A Class::MOP::Method object for the method which implements the overloading. This is optional.
• coderef 🧩 — A coderef which implements the overloading. Either this or the method_name option must be passed.
• coderef_package 📦 — The package where the coderef was defined. This is required if coderef is passed.
• coderef_name 🏷️ — The name of the coderef. This can be "__ANON__". This is required if coderef is passed.
• associated_metaclass 🔗 — A Class::MOP::Module object for the associated class or role. This is optional.

🧰 Instance Methods

• $overload->operator — Returns the operator 🎛️ for this overload object.
• $overload->method_name — Returns the method name 📛 that implements overloading, if it has one.
• $overload->has_method_name — Returns true ✅ if the object has a method name.
• $overload->method — Returns the Class::MOP::Method 📦 that implements overloading, if it has one.
• $overload->has_method — Returns true ✅ if the object has a method.
• $overload->coderef — Returns the coderef 🧩 that implements overloading, if it has one.
• $overload->has_coderef — Returns true ✅ if the object has a coderef.
• $overload->coderef_package — Returns the package 📦 for the coderef that implements overloading, if it has one.
• $overload->has_coderef — Returns true ✅ if the object has a coderef package.
• $overload->coderef_name — Returns the sub name 🏷️ for the coderef that implements overloading, if it has one.
• $overload->has_coderef_name — Returns true ✅ if the object has a coderef name.
• $overload->is_anonymous — Returns true ✅ if the overloading is implemented by an anonymous coderef.
• $overload->associated_metaclass — Returns the Class::MOP::Module 🔗 (class or role) that is associated with the overload object.
• $overload->clone — Clones 📋 the overloading object, setting original_overload in the process.
• $overload->original_overload — For cloned objects, this returns the Class::MOP::Overload object from which they were cloned. This can be used to determine the source of an overloading in a class that came from a role, for example.
