NAME

Data::Compare::Plugins::Set::Object - plugin for Data::Compare to handle Set::Object objects

VERSION

This document describes Data::Compare::Plugins::Set::Object version 1.0

SYNOPSIS

use Set::Object 'set';
use Data::Compare;

my $foo = {
    list => [ qw(one two three) ],
    set  => set( [1], [2], [3] ),
};
my $bar = {
    list => [ qw(one two three) ],
    set  => set( [1], [2], [3] ),
};

say 'Sets in $foo and $bar are ',
    $foo->{set} == $bar->{set} ? '' : 'NOT ', 'identical.';
say 'Data within $foo and $bar are ',
    Compare($foo, $bar) ? '' : 'NOT ', 'equal.';

DESCRIPTION

Enables Data::Compare to Do The Right Thing for Set::Object objects. Set::Object already has an equals() method, but it only returns true if objects within two sets are exactly equal (i.e. have the same references, referring to the same object instance). When using Data::Compare in conjuction with this plugin, objects in sets are considered the same if their contents are the same. This extends down to sets that contain arrays, hashes, or other objects supported by Data::Compare plugins.

INTERFACE

As a plugin to Data::Compare, the interface is the same as Data::Compare itself: pass the reference to two data structures to the Compare function, which for historical reasons is exported by default.

Set::Object also can export certain functions, and overloads comparison operators pertaining to sets. Consult the Set::Object documentation for more information.

DIAGNOSTICS

See the documentation for Data::Compare.
