50 This distribution is deprecated. The features it provides have been
51 added to the Moose core code as Moose::Meta::Attribute::Native. This
52 distribution should not be used by any new code.
53 While Moose attributes provide you with a way to name your accessors,
55 readers, writers, clearers and predicates, this library provides
56 commonly used attribute helper methods for more specific types of data.
57 As seen in the "SYNOPSIS", you specify the extension via the
59 "metaclass" parameter. Available meta classes are:
60
62 provides
63 This points to a hashref that uses "provider" for the keys and "method"
64 for the values. The method will be added to the object itself and do
65 what you want.
66 curries
68 This points to a hashref that uses "provider" for the keys and has two
69 choices for the value:
70 You can supply "{method => [ @args ]}" for the values. The method will
72 be added to the object itself (always using @args as the beginning
73 arguments).
74 Another approach to curry a method provider is to supply a coderef
76 instead of an arrayref. The code ref takes $self, $body, and any
77 additional arguments passed to the final method.
78 # ...
80 curries => {
82 grep => {
83 times_with_day => sub {
84 my ($self, $body, $datetime) = @_;
85 $body->($self, sub { $_->ymd eq $datetime->ymd });
86 }
87 }
88 }
89 # ...
91 $obj->times_with_day(DateTime->now); # takes datetime argument, checks day
93
95 Number
96 Common numerical operations.
97 String
99 Common methods for string operations.
100 Counter
102 Methods for incrementing and decrementing a counter attribute.
103 Bool
105 Common methods for boolean values.
106 Collection::Hash
108 Common methods for hash references.
109 Collection::ImmutableHash
111 Common methods for inspecting hash references.
112 Collection::Array
114 Common methods for array references.
115 Collection::List
117 Common list methods for array references.
118
120 The functionality in this family of modules is now implemented in the
121 Moose core as Moose::Meta::Attribute::Native. No more development is
122 being done on MooseX::AttributeHelpers, so we encourage you to switch
123 to native attribute traits.
