NAME¶
Data::Perl - Base classes wrapping fundamental Perl data types.
VERSION¶
version 0.002009
SYNOPSIS¶
use Data::Perl;
my $array = array(1,2,3, qw/a b c/);
$array->count; # 6
my @elements = $array->grep(sub {/b/}); # (b)
my $hash = hash(a => 1, b => 2);
$hash->keys; # ('a', 'b');
my $number = number(5);
$number->add(10); # 15
my $string = string("foo\n");
$string->chomp; # return 1, chomps string
my $counter = counter();
$counter->inc; # counter is now 1
my $sub = code(sub { 'foo' });
$sub->execute; # returns 'foo'
$foo
DESCRIPTION¶
Data::Perl is a collection of classes that wrap fundamental data types that
exist in Perl. These classes and methods as they exist today are an attempt to
mirror functionality provided by Moose's Native Traits. One important thing to
note is all classes currently do no validation on constructor input.
Data::Perl is a container class for the following classes:
- •
- Data::Perl::Collection::Hash
- •
- Data::Perl::Collection::Array
- •
- Data::Perl::String
- •
- Data::Perl::Number
- •
- Data::Perl::Counter
- •
- Data::Perl::Bool
- •
- Data::Perl::Code
ALPHA API¶
The API provided by these modules is as of now considered alpha and undecided.
The API
WILL change. If you are writing code that you will not touch
again for years, do not use this until this warning is removed.
PROVIDED FUNCTIONS¶
Data::Perl exports helper constructor functions to interface with the above
classes:
- •
- hash(key, value, ...)
Returns a Data::Perl::Collection::Hash object initialized with the
optionally passed in key/value args.
- •
- array(@args)
Returns a Data::Perl::Collection::Array object initialized with the
optionally passed in values.
- •
- string($arg)
Returns a Data::Perl::String object initialized with the optionally passed
in scalar arg.
- •
- number($arg)
Returns a Data::Perl::Number object initialized with the optionally passed
in scalar arg.
- •
- counter($arg)
Returns a Data::Perl::Counter object initialized with the optionally passed
in scalar arg.
- •
- bool($arg)
Returns a Data::Perl::Bool object initialized with the truth value of the
passed in scalar arg.
- •
- code($arg)
Returns a Data::Perl::Code object initialized with the optionally passed in
scalar coderef as an arg.
THANKS¶
Much thanks to the Moose team for their work with native traits, for which much
of this work is based.
