is_overloaded¶

   if (is_overloaded($class_or_object)) { ... }

Returns a boolean indicating whether the given class or object has any overloading declared. Note that a bare "use overload;" with no actual operators counts as being overloaded.

Equivalent to overload::Overloaded(), but doesn't trigger various bugs associated with it in versions of perl before 5.16.

overload_info¶

    my $info = overload_info($class_or_object);

Returns a hash reference with information about all the overloaded operators of the argument, which can be either a class name or a blessed object. The keys are the overloaded operators, as specified in %overload::ops (see "Overloadable Operations" in overload).

class

The name of the class in which the operator overloading was declared.

code

A reference to the function implementing the overloaded operator.

code_name

The name of the function implementing the overloaded operator, as returned by "sub_fullname" in Sub::Identify.

method_name (optional)

The name of the method implementing the overloaded operator, if the overloading was specified as a named method, e.g. "use overload $op => 'method';".

code_class (optional)

The name of the class in which the method specified by "method_name" was found.

value (optional)

For the special "fallback" key, the value it was given in "class".
