NAME
    Class::MOP::Overload - Overload Meta Object

VERSION
    version 2.2200

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.

  $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.
