NAME
fields::aliased - create aliases for fields
SYNOPSIS
package MyPackage;
use strict;
use fields::aliased;
use fields qw($scalar @array %hash);
sub new {
my $self = fields::new(shift);
fields::aliased::init($self);
use fields::aliased qw($self $scalar @array %hash);
$scalar = 1;
@array = ('foo', 'bar');
%hash = ('foo' => 'bar', 'baz' => 'huh?');
return $self;
}
sub myMethod {
my MyPackage $self = shift;
use fields::aliased qw($self $scalar @array %hash);
...
}
DESCRIPTION
This module is a companion to the 'fields' module, which allows efficient handling of instance variables with checking at compile time. 'fields::aliased' goes one step further and creates lexical aliases to the fields used by a method, so that they can be used as regular lexical variables. This makes code shorter and also easier to read.
CHANGES
Version 1.04 admits that the private fields in superclasses thing isn't going to work transparently, and stops trying to initialize them.
Version 1.03 make some changes so that private fields in superclasses work as expected.
Version 1.02 adds some additional code in the XS source (a function I am using turns out not to be universally available).
Version 1.01 corrects the MANIFEST.
Version 1.00 was the initial release.
