Devel::OverloadInfo(3)User Contributed Perl DocumentatioDevel::OverloadInfo(3)

NAME
       Devel::OverloadInfo - introspect	overloaded operators

VERSION
       version 0.005

DESCRIPTION
       Devel::OverloadInfo returns information about overloaded	operators for
       a given class (or object), including where in the inheritance hierarchy
       the overloads are declared and where the	code implementing them is.

FUNCTIONS
   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_op_info
	   my $info = overload_op_info($class_or_object, $op);

       Returns a hash reference	with information about the specified
       overloaded operator of the named	class or blessed object.

       Returns "undef" if the operator is not overloaded.

       See "Overloadable Operations" in	overload for the available operators.

       The keys	in the returned	hash are as follows:

       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".

   overload_info
	   my $info = overload_info($class_or_object);

       Returns a hash reference	with information about all the overloaded
       operators of specified class name or blessed object.  The keys are the
       overloaded operators, as	specified in %overload::ops (see "Overloadable
       Operations" in overload), and the values	are the	hashes returned	by
       "overload_op_info".

CAVEATS
       Whether the "fallback" key exists when it has its default value of
       "undef" varies between perl versions: Before 5.18 it's there, in	later
       versions	it's not.
