NAME

Moo::Role - Minimal Object Orientation support for Roles

SYNOPSIS

package My::Role;use Moo::Role;use strictures 2;sub foo { ... }sub bar { ... }has baz => (  is => 'ro',);1;

And elsewhere:

package Some::Class;use Moo;use strictures 2;# bar gets imported, but not foowith 'My::Role';sub foo { ... }1;

DESCRIPTION

Moo::Role builds uponRole::Tiny, so look there for most of the documentation on how this works (in particular, usingMoo::Role also enablesstrict andwarnings). The main addition here is extra bits to make the roles more "Moosey;" which is to say, it adds"has".

IMPORTED SUBROUTINES

See"IMPORTED SUBROUTINES" in Role::Tiny for all the other subroutines that are imported by this module.

has

has attr => (  is => 'ro',);

Declares an attribute for the class to be composed into. See"has" in Moo for all options.

CLEANING UP IMPORTS

Moo::Role cleans up its own imported methods and any imports declared before theuse Moo::Role statement automatically. Anything imported afteruse Moo::Role will be composed into consuming packages. A package that consumes this role:

package My::Role::ID;use Digest::MD5 qw(md5_hex);use Moo::Role;use Digest::SHA qw(sha1_hex);requires 'name';sub as_md5  { my ($self) = @_; return md5_hex($self->name);  }sub as_sha1 { my ($self) = @_; return sha1_hex($self->name); }1;

..will now have a$self->sha1_hex() method available to it that probably does not do what you expect. On the other hand, a call to$self->md5_hex() will die with the helpful error message:Can't locate object method "md5_hex".

See"CLEANING UP IMPORTS" in Moo for more details.
