Moo::Role - Minimal Object Orientation support for Roles

See Moo for authors.

Moo::Role cleans up its own imported methods and any imports declared before the "use Moo::Role" statement automatically. Anything imported after "use 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.

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

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.
