SYNOPSIS <\/a> <\/h2>\n

my $meta = Class\u2212>meta;
my $overload = $meta\u2212>get_overloaded_operator(‘+’);
if ( $overload\u2212>has_method_name ) {

}<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

This class provides meta information for overloading in classes and roles.<\/p>\n

INHERITANCE <\/a> <\/h2>\n

“Class::MOP::Overload” is a subclass of Class::MOP::Object.<\/p>\n

METHODS <\/a> <\/h2>\n

Class::MOP::Overload\u2212>new(%options)<\/b>
This method creates a new “Class::MOP::Overload” object. It accepts a number of options:<\/p>\n\n\n
<\/td>\n\n

\u2022<\/p>\n<\/td>\n

<\/td>\n\n

operator<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

This is a string that matches an operator known by the overload module, such as “” or “+”. This is required.<\/p>\n\n\n
<\/td>\n\n

\u2022<\/p>\n<\/td>\n

<\/td>\n\n

method_name<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

The name of the method which implements the overloading. Note that this does not need to actually correspond to a real method, since it\u2019s okay to declare a not-yet-implemented overloading.<\/p>\n

Either this or the “coderef” option must be passed.<\/p>\n\n\n
<\/td>\n\n

\u2022<\/p>\n<\/td>\n

<\/td>\n\n

method<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

A Class::MOP::Method object for the method which implements the overloading.<\/p>\n

This is optional.<\/p>\n\n\n
<\/td>\n\n

\u2022<\/p>\n<\/td>\n

<\/td>\n\n

coderef<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

A coderef which implements the overloading.<\/p>\n

Either this or the “method_name” option must be passed.<\/p>\n\n\n
<\/td>\n\n

\u2022<\/p>\n<\/td>\n

<\/td>\n\n

coderef_package<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

The package where the coderef was defined.<\/p>\n

This is required if “coderef” is passed.<\/p>\n\n\n
<\/td>\n\n

\u2022<\/p>\n<\/td>\n

<\/td>\n\n

coderef_name<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

The name of the coderef. This can be “__ANON__”.<\/p>\n

This is required if “coderef” is passed.<\/p>\n\n\n
<\/td>\n\n

\u2022<\/p>\n<\/td>\n

<\/td>\n\n

associated_metaclass<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

A Class::MOP::Module object for the associated class or role.<\/p>\n

This is optional.<\/p>\n

$overload\u2212>operator<\/b>
Returns the operator for this overload object.<\/p>\n

$overload\u2212>method_name<\/b>
Returns the method name that implements overloading, if it has one.<\/p>\n

$overload\u2212>has_method_name<\/b>
Returns true if the object has a method name.<\/p>\n

$overload\u2212>method<\/b>
Returns the Class::MOP::Method that implements overloading, if it has one.<\/p>\n

$overload\u2212>has_method<\/b>
Returns true if the object has a method.<\/p>\n

$overload\u2212>coderef<\/b>
Returns the coderef that implements overloading, if it has one.<\/p>\n

$overload\u2212>has_coderef<\/b>
Returns true if the object has a coderef.<\/p>\n

$overload\u2212>coderef_package<\/b>
Returns the package for the coderef that implements overloading, if it has one.<\/p>\n

$overload\u2212>has_coderef<\/b>
Returns true if the object has a coderef package.<\/p>\n

$overload\u2212>coderef_name<\/b>
Returns the sub name for the coderef that implements overloading, if it has one.<\/p>\n

$overload\u2212>has_coderef_name<\/b>
Returns true if the object has a coderef name.<\/p>\n

$overload\u2212>is_anonymous<\/b>
Returns true if the overloading is implemented by an anonymous coderef.<\/p>\n

$overload\u2212>associated_metaclass<\/b>
Returns the Class::MOP::Module (class or role) that is associated with the overload object.<\/p>\n

$overload\u2212>clone<\/b>
Clones the overloading object, setting “original_overload” in the process.<\/p>\n

$overload\u2212>original_overload<\/b>
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.<\/p>\n
