NAME¶
Class::MOP::Overload - Overload Meta Object
VERSION¶
version 2.2207
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.
