NAME
       MooseX::Traits -	Automatically apply roles at object creation time

VERSION
       version 0.13

SYNOPSIS
       Given some roles:

	 package Role;
	 use Moose::Role;
	 has foo => ( is => 'ro', isa => 'Int' required	=> 1 );

       And a class:

	 package Class;
	 use Moose;
	 with 'MooseX::Traits';

       Apply the roles to the class at "new" time:

	 my $class = Class->with_traits('Role')->new( foo => 42	);

       Then use	your customized	class:

	 $class->isa('Class'); # true
	 $class->does('Role'); # true
	 $class->foo; #	42

DESCRIPTION
       Often you want to create	components that	can be added to	a class
       arbitrarily.  This module makes it easy for the end user	to use these
       components.  Instead of requiring the user to create a named class with
       the desired roles applied, or apply roles to the	instance one-by-one,
       he can just create a new	class from yours with "with_traits", and then
       instantiate that.

       There is	also "new_with_traits",	which exists for compatibility
       reasons.	 It accepts a "traits" parameter, creates a new	class with
       those traits, and then instantiates it.

	  Class->new_with_traits( traits => [qw/Foo Bar/], foo => 42, bar => 1 )

       returns exactly the same	object as

	  Class->with_traits(qw/Foo Bar/)->new(	foo => 42, bar => 1 )

       would.  But you can also	store the result of "with_traits", and call
       other methods:

	  my $c	= Class->with_traits(qw/Foo Bar/);
	  $c->new( foo => 42 );
	  $c->whatever(	foo => 1234 );

       And so on.

METHODS
       $class->with_traits( @traits )
	   Return a new	class with the traits applied.	Use like:

       $class->new_with_traits(%args, traits =>	\@traits)
	   "new_with_traits" can also take a hashref, e.g.:

	     my	$instance = $class->new_with_traits({ traits =>	\@traits, foo => 'bar' });

ATTRIBUTES YOUR	CLASS GETS
       This role will add the following	attributes to the consuming class.

   _trait_namespace
       You can override	the value of this attribute with "default" to
       automatically prepend a namespace to the	supplied traits.  (This	can be
       overridden by prefixing the trait name with "+".)

       Example:

	 package Another::Trait;
	 use Moose::Role;
	 has 'bar' => (
	     is	      => 'ro',
	     isa      => 'Str',
	     required => 1,
	 );

	 package Another::Class;
	 use Moose;
	 with 'MooseX::Traits';
	 has '+_trait_namespace' => ( default => 'Another' );

	 my $instance =	Another::Class->new_with_traits(
	     traits => ['Trait'], # "Another::Trait", not "Trait"
	     bar    => 'bar',
	 );
	 $instance->does('Trait')	   # false
	 $instance->does('Another::Trait') # true

	 my $instance2 = Another::Class->new_with_traits(
	     traits => ['+Trait'], # "Trait", not "Another::Trait"
	 );
	 $instance2->does('Trait')	    # true
	 $instance2->does('Another::Trait') # false
