SYNOPSIS

10         package Stuff;
11         use Moose;

13         has 'options' => (
14             traits    => ['Hash'],
15             is        => 'ro',

17             default   => sub { {} },
18             handles   => {

DESCRIPTION

29       This module provides a Hash attribute which provides a number of hash-
30       like operations.
31

PROVIDED METHODS

33       These methods are implemented in
34       Moose::Meta::Attribute::Native::MethodProvider::Hash.
35
36       get($key, $key2, $key3...)
37           Returns values from the hash.
38
39           In list context return a list of values in the hash for the given
40           keys.  In scalar context returns the value for the last key
41           specified.
42
43       set($key => $value, $key2 => $value2...)
44           Sets the elements in the hash to the given values.
45
46       delete($key, $key2, $key3...)
47           Removes the elements with the given keys.
48
49       keys
50           Returns the list of keys in the hash.
51
52       exists($key)
53           Returns true if the given key is present in the hash.
54
55       defined($key)
56           Returns true if the value of a given key is defined.
57
58       values
59           Returns the list of values in the hash.
60
61       kv  Returns the key/value pairs in the hash as an array of array
62           references.
63
64             for my $pair ( $object->options->pairs ) {
65                 print "$pair->[0] = $pair->[1]\n";
66             }
67
68       elements
69           Returns the key/value pairs in the hash as a flattened list..
70
71       clear
72           Resets the hash to an empty value, like "%hash = ()".
73
74       count
75           Returns the number of elements in the hash. Also useful for not
76           empty: "has_options => 'count'".
77
78       is_empty
79           If the hash is populated, returns false. Otherwise, returns true.
80
81       accessor
82           If passed one argument, returns the value of the specified key. If
83           passed two arguments, sets the value of the specified key.
84
