NAME Class::Accessor::Array - Generate accessors/constructor for array-based object VERSION This document describes version 0.032 of Class::Accessor::Array (from Perl distribution Class-Accessor-Array), released on 2021-08-03. SYNOPSIS In lib/Your/Class.pm: package Your::Class; use Class::Accessor::Array { # constructor => 'new', accessors => { foo => 0, bar => 1, }, }; In code that uses your class: use Your::Class; my $obj = Your::Class->new; $obj->foo(1980); $obj->bar(12); or: my $obj = Your::Class->new(foo => 1, bar => 2); $obj is now: bless([1980, 12], "Your::Class"); To subclass, in lib/Your/Subclass.pm: package Your::Subclass; our @ISA = qw(Your::Class); use Class::Accessor::Array { accessors => { baz => 2, }, }; DESCRIPTION This module is a builder for array-backed classes. You can change the constructor name from the default "new" using the "constructor" parameter. Currently the built constructor does not accept parameters to set the attributes, e.g.: my $obj = Your::Class->new(foo=>1, bar=>2); # not supported You have to set the attributes manually: # supported my $obj = Your::Class->new; $obj->foo(1); $obj->bar(2); If you subclass from another class that uses Class::Accessor::Array, you must make sure that: 1) the parent class' constructor is "new"; 2) you choose attribute array indices that have not already been used (unless you deliberately want to share storage space with attributes existing in the parent class). Multiple inheritance is not supported. Note that if you're looking to reduce memory storage usage, an object based on Perl array is not that much-more-space-efficient compared to the hash-based object. Try representing an object as a pack()-ed string instead using Class::Accessor::PackedString. CONTRIBUTOR Steven Haryanto HOMEPAGE Please visit the project's homepage at .
