Public Overload Functions (Programming Perl)

13.7. Public Overload Functions

As of the 5.6 release of Perl, the use overload pragma provides the following functions for public consumption.

overload::StrVal(OBJ): This function returns the string value that OBJ would have in absence of stringification overloading ("").
overload::Overloaded(OBJ): This function returns a true value if OBJ is subject to any operator overloading at all, and false otherwise.
overload::Method(OBJ, OPERATOR): This function returns a reference to whatever code implements the overloading for OPERATOR when it operates on OBJ, or undef if no such overloading exists.
