=pod =head1 NAME Moose::Cookbook - How to cook a Moose =head1 DESCRIPTION The Moose cookbook is a series of recipes taken from the Moose test suite. Each recipe presents some code, which demonstrates some of the features of Moose, and then proceeds to explain the details of the code. We also provide a L and a L for common questions and problems people have with Moose. =head1 RECIPES =head2 Basic Moose =over 4 =item L - The (always classic) B example A simple Moose-based class. Demonstrated Moose attributes and subclassing. =item L - A simple B example A slightly more complex Moose class. Demonstrates using a method modifier in a subclass. =item L - A lazy B example Demonstrates several attribute features, including types, weak references, predicates ("does this object have a foo?"), defaults, and lazy attribute construction. =item L - Subtypes, and modeling a simple B class hierarchy Introduces the creation and use of custom types, a C method, and the use of C in a subclass. =item L - More subtypes, coercion in a B class More type examples, including the use of type coercions. =item L - The augment/inner example Demonstrates the use of C method modifiers, a way of turning the usual method overriding style "inside-out". =item L - Making Moose fast with immutable Making a class immutable greatly increases the speed of accessors and object construction. =item L - Managing complex relations with trigger (TODO) I Work off of this http://code2.0beta.co.uk/moose/svn/Moose/trunk/t/200_examples/007_Child_Parent_attr_inherit.t =item L - Builder methods and lazy_build The builder feature provides an inheritable and role-composable way to provide a default attribute value. =item L - Operator overloading, subtypes, and coercion Demonstrates how operator overloading, coercion, and sub types can be used to model how eye color is determined during reproduction. =back =head2 Moose Roles =over 4 =item L - 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. =item L - 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 if its methods conflicts with one in your class. With method exclusion and aliasing, you can work around these problems. =item L - Runtime Role Composition (TODO) I =back =head2 Meta Moose =over 4 =item L - Welcome to the meta-world (Why Go Meta?) I =item L - The meta-attribute example One way to extend Moose is to provide your own attribute metaclasses. Attribute metaclasses let you extend attribute declarations (with C) and behavior to provide additional attribute functionality. =item L - The meta-attribute trait example 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. =item L - The meta-instance example (TODO) I =item L - The meta-class example (TODO) I =back =head1 SNACKS =over 4 =item L =back =head1 SEE ALSO =over 4 =item L =back =head1 AUTHOR Stevan Little Estevan@iinteractive.comE =head1 COPYRIGHT AND LICENSE Copyright 2006-2008 by Infinity Interactive, Inc.
