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.
