NAME

Attribute::Abstract - An Abstract attribute

SYNOPSIS

  use Attribute::Abstract;

  package MyObj;
  sub new { ... }
  sub somesub: Abstract;

  package MyObj::Better;
  use base 'MyObj';
  sub somesub { return "I'm implemented!" }

DESCRIPTION

This attribute declares a subroutine to be abstract using this attribute causes a call to it to die with a suitable exception. Subclasses are expected to implement the abstract method.

Using the attribute makes it visually distinctive that a method is abstract, as opposed to declaring it without any attribute or method body, or providing a method body that might make it look as though it was implemented after all.

BUGS

None known so far. If you find any bugs or oddities, please do inform the author.
