accessors::fast - Compiletime accessors using Class::Accessor::Fast
Version 0.03
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", $_, $o->$_; }
This module was created as an alternative to use fields, and uses Class::Accessor::Fast as a base
use fields
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.
new
init
Uses Class::C3
All methods inherited from Class::Accessors::Fast. Own methods defined below
Creates blessed hash, locks it keys to current fields of this package, and invoke init method with ARGS
ARGS
Recommended to redefine in subclasses. Will be invoked by inherited new
Since this module keeps information about object fields, it can return it.
for ($o->field_list) { printf "%s: %s\n",$_,$o->$_; }
This module uses constant::def, so it behaviour could be affected by constant::abs
Use tied hash, instead of Hash::Util::lock_keys. Much more slower, but could help during development.
::lock_keys
Could be enabled by
# your main program/main.pl use constant::abs 'accessors::fast::TIE' => 1;
use Carp::confess instead of croak on error conditions
# your main program/main.pl use constant::abs 'accessors::fast::CONFESS' => 1;
This module uses warnings::register. So, warnings from it could be disabled by
no warnings 'accessors::fast';
