SYNOPSIS

12         use Data::Perl;
13
14         my $array = array(1,2,3, qw/a b c/);
15
16         $array->count; # 6
17
18         my @elements = $array->grep(sub {/b/}); # (b)
19
20         my $hash = hash(a => 1, b => 2);
21
22         $hash->keys; # ('a', 'b');
23
24         my $number = number(5);
25
26         $number->add(10); # 15
27
28         my $string = string("foo\n");
29
30         $string->chomp; # return 1, chomps string
31
32         my $counter = counter();
33
34         $counter->inc; # counter is now 1
35
36         my $sub = code(sub { 'foo' });
37
38         $sub->execute; # returns 'foo'

DESCRIPTION

43       Data::Perl is a collection of classes that wrap fundamental data types
44       that exist in Perl. These classes and methods as they exist today are
45       an attempt to mirror functionality provided by Moose's Native Traits.
46       One important thing to note is all classes currently do no validation
47       on constructor input.
48
49       Data::Perl is a container class for the following classes:
50
51       •   Data::Perl::Collection::Hash
52
53       •   Data::Perl::Collection::Array
54
55       •   Data::Perl::String
56
57       •   Data::Perl::Number
58
59       •   Data::Perl::Counter
60
61       •   Data::Perl::Bool
62
63       •   Data::Perl::Code
64

ALPHA API

66       The API provided by these modules is as of now considered alpha and
67       undecided.  The API WILL change.  If you are writing code that you will
68       not touch again for years, do not use this until this warning is
69       removed.
70

PROVIDED FUNCTIONS

72       Data::Perl exports helper constructor functions to interface with the
73       above classes:
74
75       •   hash(key, value, ...)
76
77           Returns a Data::Perl::Collection::Hash object initialized with the
78           optionally passed in key/value args.
79
80       •   array(@args)
81
82           Returns a Data::Perl::Collection::Array object initialized with the
83           optionally passed in values.
84
85       •   string($arg)
86
87           Returns a Data::Perl::String object initialized with the optionally
88           passed in scalar arg.
89
90       •   number($arg)
91
92           Returns a Data::Perl::Number object initialized with the optionally
93           passed in scalar arg.
94
95       •   counter($arg)
96
97           Returns a Data::Perl::Counter object initialized with the
98           optionally passed in scalar arg.
99
100       •   bool($arg)
101
102           Returns a Data::Perl::Bool object initialized with the truth value
103           of the passed in scalar arg.
104
105       •   code($arg)
106
107           Returns a Data::Perl::Code object initialized with the optionally
108           passed in scalar coderef as an arg.

THANKS

111       Much thanks to the Moose team for their work with native traits, for
112       which much of this work is based.
