.SH "NAME"
MooX::Traits::Util \- non\-role alternative to MooX::Traits
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Given some roles:
.PP
.Vb 3
\&   package Role;
\&   use Moo::Role;
\&   has foo => ( is => \*(Aqro\*(Aq, required => 1 );
.Ve
.PP
And a class:
.PP
.Vb 2
\&   package Class;
\&   use Moo;
.Ve
.PP
Apply the roles to the class:
.PP
.Vb 1
\&   use MooX::Traits::Util \-all;
\&   
\&   my $class = new_class_with_traits(\*(AqClass\*(Aq, \*(AqRole\*(Aq);
.Ve
.PP
Then use your customized class:
.PP
.Vb 4
\&   my $object = $class\->new( foo => 42 );
\&   $object\->isa(\*(AqClass\*(Aq); # true
\&   $object\->does(\*(AqRole\*(Aq); # true
\&   $object\->foo; # 42
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides the functionality of MooX::Traits, but it's an
exporter rather than a role.
.PP
It's inspired by, but not compatible with MooseX::Traits::Util. The
latter module is undocumented, and it's not entirely clear whether it's
intended to be consumed by end-users, or is an entirely internal \s-1API.\s0
.PP
This module exports nothing by default.

.ie n .IP """new_class_with_traits( $class, @traits )""" 4
.el .IP "\f(CWnew_class_with_traits( $class, @traits )\fR" 4
.IX Item "new_class_with_traits( $class, @traits )"
Return a new class name with the traits applied.
.Sp
This function is not quite compatible with the \f(CW\*(C`new_class_with_traits\*(C'\fR
function provided by MooseX::Traits::Util, in that the latter will
return a metaclass object.
.Sp
This function can be exported.
.ie n .IP """new_class_with_traits_one_by_one( $class, @traits )""" 4
.el .IP "\f(CWnew_class_with_traits_one_by_one( $class, @traits )\fR" 4
.IX Item "new_class_with_traits_one_by_one( $class, @traits )"
Rather than applying the the traits simultaneously, the traits are
applied one at a time. It is roughly equivalent to:
.Sp
.Vb 2
\&   use List::Util qw(reduce);
\&   use MooX::Traits::Util qw( new_class_with_traits );
\&   
\&   my $class  = ...;
\&   my @traits = ...;
\&   my $new    = reduce { new_class_with_traits($a, $b) } $class, @traits;
.Ve
.Sp
Applying traits one by one has implications for method modifiers, and
for method conflict detection. \fBUse with caution.\fR
.Sp
There is no equivalent functionality in MooseX::Traits::Util.
.Sp
This function can be exported.
.ie n .IP """resolve_traits( $class, @traits )""" 4
.el .IP "\f(CWresolve_traits( $class, @traits )\fR" 4
.IX Item "resolve_traits( $class, @traits )"
This function returns a list of traits, but does not apply them to the
class. It honours the class' \f(CW\*(C`_trait_namespace\*(C'\fR method (but only if
the class does the MooX::Traits role) and handles parameter hashrefs
for parameterizable roles. (That is, parameters are applied to the
role, and the list of traits returned by the function includes the
result of that application instead of including the original hashref.)
.Sp
This function is not quite compatible with the \f(CW\*(C`resolve_traits\*(C'\fR
function provided by MooseX::Traits::Util, in that the latter will
not handle parameter hashrefs, trusting Moose to do that.
.Sp
This function \fIcannot\fR be exported.
