NAME

       Moose::Cookbook - How to cook a Moose

VERSION

       version 2.1005

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::Point_AttributesAndSubclassing
           A simple Moose-based class. Demonstrates basic Moose attributes and subclassing.

       Moose::Cookbook::Basics::BankAccount_MethodModifiersAndSubclassing
           A slightly more complex Moose class. Demonstrates using a method modifier in a
           subclass.

       Moose::Cookbook::Basics::BinaryTree_AttributeFeatures
           Demonstrates several attribute features, including types, weak references, predicates
           ("does this object have a foo?"), defaults, laziness, and triggers.

       Moose::Cookbook::Basics::Company_Subtypes
           Introduces the creation and use of custom types, a "BUILD" method, and the use of
           "override" in a subclass. This recipe also shows how to model a set of classes that
           could be used to model companies, people, employees, etc.

       Moose::Cookbook::Basics::HTTP_SubtypesAndCoercion
           This recipe covers more subtype creation, including the use of type coercions.

       Moose::Cookbook::Basics::Immutable
           Making a class immutable greatly increases the speed of accessors and object
           construction.

       Moose::Cookbook::Basics::BinaryTree_BuilderAndLazyBuild - Builder methods and lazy_build
           The builder feature provides an inheritable and role-composable way to provide a
           default attribute value.

       Moose::Cookbook::Basics::Genome_OverloadingSubtypesAndCoercion
           Demonstrates using operator overloading, coercion, and subtypes to model how eye color
           is determined during reproduction.

       Moose::Cookbook::Basics::Person_BUILDARGSAndBUILD
           This recipe demonstrates the use of "BUILDARGS" and "BUILD" to hook into object
           construction.

       Moose::Cookbook::Basics::DateTime_ExtendingNonMooseParent
           In this recipe, we make a Moose-based subclass of DateTime, a module which does not
           use Moose itself.

       Moose::Cookbook::Basics::Document_AugmentAndInner
           Demonstrates the use of "augment" method modifiers, a way of turning the usual method
           overriding style "inside-out".

   Moose Roles
       These recipes will show you how to use Moose roles.

       Moose::Cookbook::Roles::Comparable_CodeReuse
           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::Restartable_AdvancedComposition
           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::ApplicationToInstance
           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::WhyMeta
           If you're wondering what all this "meta" stuff is, and why you should care about it,
           read this "recipe".

       Moose::Cookbook::Meta::Labeled_AttributeTrait
           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::Table_MetaclassTrait
           This recipe takes the class metaclass we saw in the previous recipe and reimplements
           it as a metaclass trait.

       Moose::Cookbook::Meta::PrivateOrPublic_MethodMetaclass
           This recipe shows a custom method metaclass that implements making a method private.

       Moose::Cookbook::Meta::GlobRef_InstanceMetaclass
           This recipe shows an example of how you create your own meta-instance class. The meta-
           instance determines the internal structure of object instances and provide access to
           attribute slots.

           In this particular instance, we use a blessed glob reference as the instance instead
           of a blessed hash reference.

       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::ExtensionOverview
           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::Debugging_BaseClassRole
           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::Mooseish_MooseSugar
           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.
