Class::Meta::Declare is a Perl module deprecated in favor of Class::Meta::Express.

SYNOPSIS

This was a first attempt at making a saner interface for Class::Meta. It is nicer, but Class::Meta::Express is nicer still. Go use that one.

package MyApp::Thingy;
use Class::Meta::Declare :all;
use Data::UUID;

Class::Meta::Declare->new(
meta => [
key => thingy,
accessors => $ACC_SEMI_AFFORDANCE,
],
attributes => [
pi => {
context => $CTXT_CLASS,
authz => $AUTHZ_READ,
default => 3.1415927,
},
id => {
authz => $AUTHZ_READ,
type => $TYPE_STRING,
default => sub { Data::UUID->new->create_str },
},
name => {
required => 1,
type => $TYPE_STRING,
default => No Name Supplied,
},
age => { type => $TYPE_INTEGER, },
],
methods => [
some_method => {
view => $VIEW_PUBLIC,
code => sub {
my $self = shift;
return [ reverse @_ ];
},
}
]
);

my $object = MyApp::Thingy->new;
print MyApp::Thingy->pi; # prints 3.1415927
print $object->name; # prints "No Name Supplied;
$object->set_name("bob");
print $object->name; # prints "bob"

This class provides an alternate interface for Class::Meta.

Class::Meta is a useful module which allows one to create Perl classes which support introspection (also known as reflection). Typically Perl classes, when created, dont supply a lot of metadata. Imported helper functions show up when you call $object->can($method). Private, protected and trusted methods are not readily supported. Fetching a list of attributes or methods is a haphazard affair. Class::Meta overcomes these shortcomings by building the classes for you and allowing you to fetch a class object:

my $class_object = $object->my_class;

foreach my $attribute ( $class_object->attributes ) {
print $attribute->name, "n";
}
foreach my $method ( $class_object->methods ) {
print $method->name, "n";
}

If youve set up your class correctly, these properties are now easy to discover.

Unfortunately, many find the Class::Meta interface to be a bit clumsy. As an alternative, Class::Meta::Declare allows you to declare your entire class in a single argument list to the constructor and have the class built for you automatically. Further, reasonable defaults are provided for just about everything.

IMPORTANT: You want this class or Class::Meta if you need an introspection API for your classes. If you do not need introspection or dynamic class generation, these modules are overkill.

Class::Meta::Type is a Perl module for data type validation and accessor building.

SYNOPSIS

package MyApp::TypeDef;

use strict;
use Class::Meta::Type;
use IO::Socket;

my $type = Class::Meta::Type->add( key => io_socket,
desc => IO::Socket object,
name => IO::Socket Object );

This class stores the various data types used by Class::Meta. It manages all aspects of data type validation and method creation. New data types can be added to Class::Meta::Type by means of the add() constructor. This is useful for creating custom types for your Class::Meta-built classes.

Note:This class manages the most advanced features of Class::Meta. Before deciding to create your own accessor closures as described in add(), you should have a thorough working knowledge of how Class::Meta works, and have studied the add() method carefully. Simple data type definitions such as that shown in the SYNOPSIS, on the other hand, are encouraged.

VBA Express is a frontend for the very popular game emulator VisualBoyAdvance.

Whats VBA Express? Its First, to configure VisualBoyAdvance (emulator)... EASILY! Graphics, sound, controls (keyboard and joystick), paths (to saves and captures)... You can configure all this without edit VisualBoyAdvance.cfg manually!

Open your Roms (games) with the frontend! You can run the roms with "Play!" button (without using the console command VisualBoyAdvance game.rom).

Class::Cloneable is a base class for Cloneable objects.

SYNOPSIS

package MyObject;
our @ISA = (Class::Cloneable);

# calling clone on an instance of MyObject
# will give you full deep-cloning functionality

This module provides a flexible base class for building objects with cloning capabilities. This module does its best to respect the encapsulation of all other objects, including subclasses of itself. This is intended to be a stricter and more OO-ish option than the more general purpose Clone and Clone::PP modules.

Class::MOP is a Meta Object Protocol for Perl 5.

SYNOPSIS

# ... This will come later, for now see
# the other SYNOPSIS for more information

This module is an attempt to create a meta object protocol for the Perl 5 object system. It makes no attempt to change the behavior or characteristics of the Perl 5 object system, only to create a protocol for its manipulation and introspection.

That said, it does attempt to create the tools for building a rich set of extensions to the Perl 5 object system. Every attempt has been made for these tools to keep to the spirit of the Perl 5 object system that we all know and love.

This documentation is admittedly sparse on details, as time permits I will try to improve them. For now, I suggest looking at the items listed in the "SEE ALSO" section for more information. In particular the book "The Art of the Meta Object Protocol" was very influential in the development of this system.

What is a Meta Object Protocol?

A meta object protocol is an API to an object system.

To be more specific, it is a set of abstractions of the components of an object system (typically things like; classes, object, methods, object attributes, etc.). These abstractions can then be used to both inspect and manipulate the object system which they describe.

It can be said that there are two MOPs for any object system; the implicit MOP, and the explicit MOP. The implicit MOP handles things like method dispatch or inheritance, which happen automatically as part of how the object system works. The explicit MOP typically handles the introspection/reflection features of the object system. All object systems have implicit MOPs, without one, they would not work. Explict MOPs however as less common, and depending on the language can vary from restrictive (Reflection in Java or C#) to wide open (CLOS is a perfect example).

Class::ArrayObjects is a Perl utility class for array based objects.

SYNOPSIS

package Some::Class;
use Class::ArrayObjects define => {
fields => [qw(_foo_ _bar_ BAZ)],
};

or

package Other::Class;
use base Some::Class;
use Class::ArrayObjects extend => {
class => Some::Class,
with => [qw(_zorg_ _fnord_ BEZ)],
import => 1,
};

This module is little more than a cute way of defining constant subs in your own package. Constant subs are very useful when dealing with array based objects because they allow one to access array slots by name instead of by index.

mediadbs is a project that aims to produce a flexible database system for tracking and searching for multiple forms of electronic media (eg mp3, divx, ogg) distributed on multiple servers in a local network. It currently only supports mp3 format files.
