Release of version 0.01 of Attribute::Handlers::Prospective

NAME

Attribute::Handlers::Prospective - Enhanced definition of attribute handlers

DESCRIPTION

This module, when inherited by a package, allows that package's class to define attribute handler subroutines for specific attributes. Variables and subroutines subsequently defined in that package, or in packages derived from that package may be given attributes with the same names as the attribute handler subroutines, which will then be called at the end of the compilation phase (i.e. in an INIT block).

EXAMPLE

        package UNIVERSAL;
        use Attribute::Handlers::Prospective;

        my %name;
        sub name { return $name{$_[2]}||*{$_[1]}{NAME} }

        sub Name    :ATTR(RAWDATA) {
                $name{$_[2]} = $_[4]
        }

        sub Purpose :ATTR(RAWDATA) {
                print STDERR "Purpose of ", &name, " is $_[4]\n"
        }

        sub Unit    :ATTR(RAWDATA) {
                print STDERR &name, " measured in $_[4]\n"
        }

        package main;

        my $capacity : Name(capacity)
                     : Purpose(to store max storage capacity for files)
                     : Unit(Gb);

        package Other;

        sub foo : Purpose(to foo all data before barring it) { }
