NAME

Object::Array - array references with accessors

CONTENTS

VERSION

Version 0.060

SYNOPSIS



  use Object::Array qw(Array);
  my $array = Object::Array->new;       # or
  $array = Object::Array->new(\@array); # or
  $array = Array(\@array);
  $array->push(1..5);
  print $array->shift;
  $_++ for grep { $_ < 4 } @{ $array };
  $array->[0] = "a pony";



IMPORTANT NOTE

Several of these methods do not behave exactly like their builtin counterparts.

Specifically, any method that you would expect to return a list does so, but <B>only in list contextB>. In scalar context, these methods will return an Object::Array object constructed from a copy of the list that would have been returned.

This sounds more complicated than it is. It means that you can chain some methods together, e.g.



  $arr->grep(sub { defined })->[-1];



instead of the more bracing



  ${ $arr->grep(sub { defined }) }[-1];



Currently, these array objects only contain copies of the original values. In the future, they will retain references to the original object, and this sort of thing will be possible:



  $arr->grep(sub { defined })->[-1]++;



METHODS

    new



  my $array = Object::Array->new;
  # or use existing array
  my $array = Object::Array->new(\@a);



Creates a new array object, either from scratch or from an existing array.

Using an existing array will mean that any changes to $array also affect the original array object. If you don’t want that, copy the data first or use something like Storable’s dclone.

    isa

Overridden to respond to ’ARRAY’.

    ref

Returns a reference to the underlying array.
