NAME

       Validation::Class::Exporter - Simple Exporter for Validation::Class Classes

VERSION

       version 7.70

SYNOPSIS

	   package MyApp::Class;

	   use Validation::Class;
	   use Validation::Class::Exporter;

	   Validation::Class::Exporter->apply_spec(
	       routines => ['thing'], # export routines as is
	       settings => [ ... ] # passed to the "load" method, see Validation::Class
	   );

	   has foo => 0;

	   bld sub {

	       shift->foo(1);

	   };

	   sub thing {

	       my $args = pop;

	       my $class = shift || caller;

	       # routine as a keyword

	       $class->{config}->{THING} = [$args];

	   };

	   package MyApp::Example;

	   use MyApp::Class;

	   thing ['this' => 'that'];

	   package main;

	   my $eg = MyApp::Example->new; # we have lift-off!!!

DESCRIPTION

       This module (while experimental) encapsulates the exporting of keywords and routines. It applies the Validation::Class framework along with
       any keyword routines and/or sub-routines specified with the apply_spec() method. It does this by simply by copying the spec into the
       calling class.

       To simplify writing exporter modules, "Validation::Class::Exporter" also imports "strict" and "warnings" into your exporter module, as well
       as into modules that use it.

METHODS

   apply_spec
       When you call this method, "Validation::Class::Exporter" builds a custom "import" method on the calling class. The "import" method will
       export the functions you specify, and can also automatically export "Validation::Class" making the calling class a Validation::Class
       derived class.

       This method accepts the following parameters:

       o       routines => [ ... ]

	       This list of function names only will be exported into the calling class exactly as is, the functions can be used traditionally or
	       as keywords so their parameter handling should be configured accordingly.

       o       settings => [ ... ]

	       This list of key/value pair will be passed to the load method imported from "Validation::Class::load" and will be applied on the
	       calling class.

	       This approach affords you some trickery in that you can utilize the load method to apply the current class' configuration to the
	       calling class' configuration, etc.

NAME

       Moose::Util::MetaRole - Apply roles to any metaclass, as well as the object base class

VERSION

       version 2.0603

SYNOPSIS

	 package MyApp::Moose;

	 use Moose ();
	 use Moose::Exporter;
	 use Moose::Util::MetaRole;

	 use MyApp::Role::Meta::Class;
	 use MyApp::Role::Meta::Method::Constructor;
	 use MyApp::Role::Object;

	 Moose::Exporter->setup_import_methods( also => 'Moose' );

	 sub init_meta {
	     shift;
	     my %args = @_;

	     Moose->init_meta(%args);

	     Moose::Util::MetaRole::apply_metaroles(
		 for		 => $args{for_class},
		 class_metaroles => {
		     class => => ['MyApp::Role::Meta::Class'],
		     constructor => ['MyApp::Role::Meta::Method::Constructor'],
		 },
	     );

	     Moose::Util::MetaRole::apply_base_class_roles(
		 for   => $args{for_class},
		 roles => ['MyApp::Role::Object'],
	     );

	     return $args{for_class}->meta();
	 }

DESCRIPTION

       This utility module is designed to help authors of Moose extensions write extensions that are able to cooperate with other Moose
       extensions. To do this, you must write your extensions as roles, which can then be dynamically applied to the caller's metaclasses.

       This module makes sure to preserve any existing superclasses and roles already set for the meta objects, which means that any number of
       extensions can apply roles in any order.

USAGE

       The easiest way to use this module is through Moose::Exporter, which can generate the appropriate "init_meta" method for you, and make sure
       it is called when imported.

FUNCTIONS

       This module provides two functions.

   apply_metaroles( ... )
       This function will apply roles to one or more metaclasses for the specified class. It will return a new metaclass object for the class or
       role passed in the "for" parameter.

       It accepts the following parameters:

       o   for => $name

	   This specifies the class or for which to alter the meta classes. This can be a package name, or an appropriate meta-object (a
	   Moose::Meta::Class or Moose::Meta::Role).

       o   class_metaroles => \%roles

	   This is a hash reference specifying which metaroles will be applied to the class metaclass and its contained metaclasses and helper
	   classes.

	   Each key should in turn point to an array reference of role names.

	   It accepts the following keys:

	   class
	   attribute
	   method
	   wrapped_method
	   instance
	   constructor
	   destructor
	   error
       o   role_metaroles => \%roles

	   This is a hash reference specifying which metaroles will be applied to the role metaclass and its contained metaclasses and helper
	   classes.

	   It accepts the following keys:

	   role
	   attribute
	   method
	   required_method
	   conflicting_method
	   application_to_class
	   application_to_role
	   application_to_instance
	   application_role_summation
	   applied_attribute

   apply_base_class_roles( for => $class, roles => @roles )
       This function will apply the specified roles to the object's base class.
