This class provides meta information for overloading in classes and roles.
Class::MOP::Overload is a subclass of the Class::MOP::Object manpage.
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 the Class::MOP::Method manpage 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 the Class::MOP::Module manpage object for the associated class or role.
This is optional.
Returns the operator for this overload object.
Returns the method name that implements overloading, if it has one.
Returns true if the object has a method name.
Returns the the Class::MOP::Method manpage that implements overloading, if it has one.
Returns true if the object has a method.
Returns the coderef that implements overloading, if it has one.
Returns true if the object has a coderef.
Returns the package for the coderef that implements overloading, if it has
one.
Returns true if the object has a coderef package.
Returns the sub name for the coderef that implements overloading, if it has
one.
Returns true if the object has a coderef name.
Returns true if the overloading is implemented by an anonymous coderef.
Returns the the Class::MOP::Module manpage (class or role) that is associated with the
overload object.
Clones the overloading object, setting original_overload in the process.
For cloned objects, this returns the the Class::MOP::Overload manpage 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.
