accessors::fast(3)

NAME
accessors::fast - Compiletime accessors using Class::Accessor::Fast

VERSION
Version 0.03

SYNOPSIS
        package My::Simple::Package;
        use accessors::fast qw(field1 field2);

        # constructor is private, redefine only init;
        sub init {
                my $self = shift;
                my %args = @_;
                $self->field1($args{arg1});
        }

        package main;
        my $o = My::Simple::Package->new( arg1 => 'some value' );
        print $o->field1; # some value

        for ($o->field_list) {
                printf "object have field %s with value %s\n", $_, $o->$_;
        }

DESCRIPTION
This module was created as an alternative to "use fields", and uses Class::Accessor::Fast as a base

Creates accessors at compiletime

Have own default "new" method: it creates object as a blessed hash, then locks keys to defined field list, and invoke "init". So, recommended usage inside packages, is access by hash keys (it's 3 times faster then accessor). Since keys are locked, you will not suffer from autovivification. Public interface recommended to be documented as accessors.

Uses Class::C3

METHODS
All methods inherited from Class::Accessors::Fast. Own methods defined below

  new( ARGS )
Creates blessed hash, locks it keys to current fields of this package, and invoke "init" method with "ARGS"

  init( ARGS )
Recommended to redefine in subclasses. Will be invoked by inherited "new"

  field_list
Since this module keeps information about object fields, it can return it.

        for ($o->field_list) {
                printf "%s: %s\n",$_,$o->$_;
        }

FEATURES
This module uses constant::def, so it behaviour could be affected by constant::abs

  TIE [ = 0 ]
Use tied hash, instead of Hash::Util"::lock_keys". Much more slower, but could help during development.

Could be enabled by

        # your main program/main.pl
        use constant::abs 'accessors::fast::TIE' => 1;

  CONFESS [ = 0 ]
use Carp::confess instead of croak on error conditions

Could be enabled by

        # your main program/main.pl
        use constant::abs 'accessors::fast::CONFESS' => 1;

  warnings
This module uses warnings::register. So, warnings from it could be disabled by

        no warnings 'accessors::fast';
