This class provides meta information for overloading in classes and roles.
"Class::MOP::Overload" is a subclass of Class::MOP::Object.
This method creates a new "Class::MOP::Overload" object. It accepts a number of options:
This is a string that matches an operator known by the overload module, such as "" or "+". This is required.
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.
A Class::MOP::Method object for the method which implements the overloading.
This is optional.
A coderef which implements the overloading.
Either this or the "method_name" option must be passed.
The package where the coderef was defined.
This is required if "coderef" is passed.
The name of the coderef. This can be "__ANON__".
This is required if "coderef" is passed.
A Class::MOP::Module 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 Class::MOP::Method 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 Class::MOP::Module (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 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.
