moo::role5.18
Moo::Role(3) User Contributed Perl Documentation Moo::Role(3)
NAME
Moo::Role - Minimal Object Orientation support for Roles
SYNOPSIS
package My::Role;
use Moo::Role;
sub foo { ... }
sub bar { ... }
has baz => (
is => 'ro',
);
1;
And elsewhere:
package Some::Class;
use Moo;
# bar gets imported, but not foo
with('My::Role');
sub foo { ... }
1;
DESCRIPTION
"Moo::Role" builds upon Role::Tiny, so look there for most of the documentation on how this works. 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 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.
