NAME

Object::Array::Plugin::Builtins

SYNOPSIS

See Object::Array.

Provides analogues to Perl's built-in array operations.

METHODS

size

length

Returns the number of elements in the array.

size and length are synonyms.

element

elem

  print $array->elem(0);
  print $array->[0];

Get a single element's value.

  $array->elem(1 => "hello");
  $array->[1] = "hello";

Set a single element's value.

element and elem are synonyms.

slice

  print for $array->slice([ 0, 1, 2 ]);
  print for @{$array}[0,1,2];

Get multiple values.

  $array->slice([ 0, 1, 2 ] => [ qw(a b c) ]);
  @{$array}[0,1,2] = qw(a b c);

Set multiple values.

elements

elems

Shortcut for all values in the array.

elements and elems are synonyms.

NOTE: Using methods in a for/map/etc. will not do aliasing via $_. Use array dereferencing if you need to do this, e.g.

  $_++ for @{$array};

clear

Erase the array. The following all leave the array empty:

  $array->size(0);
  $array->clear;
  @{ $array } = ();

push

pop

shift

unshift

exists

delete

splice

map

grep

join

As the builtin array operations of the same names.

Note that since map and grep are called as methods, you must use <sub { }> (no bare blocks).
