NAME

Moose::Cookbook - How to cook a Moose

DESCRIPTION

The Moose cookbook is a series of recipes showing various Moose
features. Most recipes present some code demonstrating some feature,
and then explain the details of the code.

You should probably read the Moose::Manual first. The manual explains
Moose concepts without being too code-heavy.

RECIPES

Basic Moose: These recipes will give you a good overview of Moose's capabilities,
starting with simple attribute declaration, and moving on to more
powerful features like laziness, types, type coercion, method
modifiers, and more.; Moose::Cookbook::Basics::Recipe1 - The (always classic) Point example
A simple Moose-based class. Demonstrates Moose attributes and
subclassing.; Moose::Cookbook::Basics::Recipe2 - A simple BankAccount example
A slightly more complex Moose class. Demonstrates using a method
modifier in a subclass.; Moose::Cookbook::Basics::Recipe3 - A lazy BinaryTree example
Demonstrates several attribute features, including types, weak
references, predicates ("does this object have a foo?"), defaults, laziness, and triggers.; Moose::Cookbook::Basics::Recipe4 - Subtypes, and modeling a simple
Company class hierarchy
Introduces the creation and use of custom types, a "BUILD" method, and the use of "override" in a subclass.; Moose::Cookbook::Basics::Recipe5 - More subtypes, coercion in a Request class
More type examples, including the use of type coercions.; Moose::Cookbook::Basics::Recipe6 - The augment/inner example
Demonstrates the use of "augment" method modifiers, a way of
turning the usual method overriding style "inside-out".; Moose::Cookbook::Basics::Recipe7 - Making Moose fast with immutable
Making a class immutable greatly increases the speed of accessors
and object construction.; Moose::Cookbook::Basics::Recipe8 - Builder methods and lazy_build
The builder feature provides an inheritable and role-composable way to provide a default attribute value.; Moose::Cookbook::Basics::Recipe9 - Operator overloading, subtypes, and coercion
Demonstrates using operator overloading, coercion, and subtypes to model how eye color is determined during reproduction.; Moose::Cookbook::Basics::Recipe10 - Using BUILDARGS and BUILD to hook
into object construction
This recipe demonstrates the use of "BUILDARGS" and "BUILD" to hook into object construction.; Moose::Cookbook::Basics::Recipe11 - Extending a non-Moose base class
In this recipe, we make a Moose-based subclass of DateTime, a
module which does not use Moose itself.
Moose Roles: These recipes will show you how to use Moose roles.; Moose::Cookbook::Roles::Recipe1 - The Moose::Role example
Demonstrates roles, which are also sometimes known as traits or
mix-ins. Roles provide a method of code re-use which is orthogonal to subclassing.; Moose::Cookbook::Roles::Recipe2 - Advanced Role Composition - method
exclusion and aliasing
Sometimes you just want to include part of a role in your class.
Sometimes you want the whole role but one of its methods conflicts with one in your class. With method exclusion and aliasing, you can work around these problems.; Moose::Cookbook::Roles::Recipe3 - Applying a role to an object instance
In this recipe, we apply a role to an existing object instance.
Meta Moose: These recipes show you how to write your own meta classes, which lets
you extend the object system provided by Moose.; Moose::Cookbook::Meta::Recipe1 - Welcome to the meta-world (Why Go
Meta?)
If you're wondering what all this "meta" stuff is, and why you
should care about it, read this "recipe".; Moose::Cookbook::Meta::Recipe2 - A meta-attribute, attributes with
labels
One way to extend Moose is to provide your own attribute
metaclasses. Attribute metaclasses let you extend attribute
declarations (with "has") and behavior to provide additional
attribute functionality.; Moose::Cookbook::Meta::Recipe3 - Labels implemented via attribute
traits
Extending Moose's attribute metaclass is a great way to add
functionality. However, attributes can only have one metaclass.
Applying roles to the attribute metaclass lets you provide
composable attribute functionality.; Moose::Cookbook::Meta::Recipe4 - Adding a "table" attribute to the
metaclass
If you want to store more information about your classes, you'll
have to extend "Moose::Meta::Class". Doing so is simple, but you'll probably also want to provide some sugar, so see
Moose::Cookbook::Extending::Recipe2 as well.; Moose::Cookbook::Meta::Recipe5 - The "table" attribute implemented as a metaclass trait
This recipe takes the class metaclass we saw in the previous recipe and reimplements it as a metaclass trait.; Moose::Cookbook::Meta::Recipe6 - A method metaclass for marking methods public or private
This recipe shows a custom method metaclass that implements making a method private.; Moose::Cookbook::Meta::Recipe7 - Using a blessed array reference as an object instance
This recipe shows an example of how you create your own metainstance class. The meta-instance determines the internal structure of object instances and provide access to attribute slots.; Moose::Cookbook::Meta::Recipe8 - Hooking into immutabilization (TODO)
Moose has a feature known as "immutabilization". By calling
"__PACKAGE__->meta()->make_immutable()" after defining your class
(attributes, roles, etc), you tell Moose to optimize things like
object creation, attribute access, and so on.

If you are creating your own metaclasses, you may need to hook into the immutabilization system. This cuts across a number of spots,
including the metaclass class, meta method classes, and possibly
the meta-instance class as well.

This recipe shows you how to write extensions which immutabilize
properly.
Extending Moose: These recipes cover some more ways to extend Moose, and will be useful if you plan to write your own "MooseX" module.; Moose::Cookbook::Extending::Recipe1 - Moose extension overview
There are quite a few ways to extend Moose. This recipe provides an overview of each method, and provides recommendations for when each is appropriate.; Moose::Cookbook::Extending::Recipe2 - Providing a base object class
role
Many base object class extensions can be implemented as roles. This example shows how to provide a base object class debugging role
that is applied to any class that uses a notional
"MooseX::Debugging" module.; Moose::Cookbook::Extending::Recipe3 - Providing an alternate base
object class
You may find that you want to provide an alternate base object
class along with a meta extension, or maybe you just want to add
some functionality to all your classes without typing "extends
'MyApp::Base'" over and over.; Moose::Cookbook::Extending::Recipe4 - Acting like Moose.pm and
providing sugar Moose-style
This recipe shows how to provide a replacement for "Moose.pm". You may want to do this as part of the API for a "MooseX" module,
especially if you want to default to a new metaclass class or base object class.
