NAME

Data::Object::Immutable - Immutable Object for Perl 5

VERSION

version 0.07

SYNOPSIS

use Data::Object::Immutable;

my $object = Data::Object::Immutable->new([1..9]);

$object->isa('Data::Object::Array'); # 1
$object->count; # 9

$object->[0]++; # fatal ... modification of a read-only value attempted

DESCRIPTION

Data::Object::Immutable provides a mechanism for making any Data::Object data type object immutable. An immutable object is an object whose state cannot be modified after it is created; Immutable objects are often useful because they are inherently thread-safe, easier to reason about, and offer higher security than mutable objects.
