NAME

Object::Deadly - An object that dies whenever examined

VERSION

Version 0.05

SYNOPSIS

This object is meant to be used in testing. All possible overloading and method calls die. You can pass this object into methods which are not supposed to accidentally trigger any potentially overloading.

  use Object::Deadly;
  
  my $foo = Object::Deadly->new;
  print $foo; # dies

METHODS

Object::Deadly->new()
Object::Deadly->new( MESSAGE )

The class method Object::Deadly->new returns an Object::Deadly object. Dies with a stack trace and a message when evaluated in any context. The default message contains a stack trace from where the object is created.

Object::Deadly->kill_function( FUNCTION NAME )
Object::Deadly->kill_function( FUNCTION NAME, DEATH CODE REF )

The class method kill_function accepts a function name like isa, can, or similar and creates a function in the Object::Deadly::_unsafe class of the same name.

An optional second argument is a code reference to die with. This defaults to \&Object::Deadly::_death.

Object::Deadly->kill_UNIVERSAL

This class method kills all currently known UNIVERSAL functions so they can't be called on a Object::Deadly object.

Object::Deadly->get_death

Returns the function Object::Deadly::_death.

PRIVATE FUNCTIONS

The following functions are all private and not meant for public consumption.

_death( $obj )

This function temporarilly reblesses the object into Object::Deadly::_safe, extracts the message from inside of it, and confess's with it. If possible this will be Carp::Clan::confess.
