NAME
Class::Trait::Base - Base class for all Traits SYNOPSIS
This class needs to be inherited by all traits so they can be identified as traits. use Class::Trait 'base'; DESCRIPTION
Not much going on here, just an AUTOLOAD method to help properly dispatch calls to "SUPER::" and an "apply" method. ############################################################################## apply require TSomeTrait; TSomeTrait->apply($object); This method allows you to apply a trait to an object. It returns the trait so you can then reapply it: TTricks->apply($dog_object) ->apply($cat_object); This is merely syntactic sugar for the "Class::Trait::apply" method: Class::Trait->apply($dog_object, 'TTricks'); Class::Trait->apply($cat_object, 'TTricks'); SEE ALSO

NAME
MooseX::Traits - automatically apply roles at object creation time VERSION
version 0.12 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 AUTHOR
