VERSION
version 0.006
SYNOPSIS
package Example;
use Moose;
with qw(Role::HasPayload::Auto);
sub Payload { 'Role::HasPayload::Meta::Attribute::Payload' }
has height => (
is => 'ro',
traits => [ Payload ],
);
has width => (
is => 'ro',
traits => [ Payload ],
);
has color => (
is => 'ro',
);
...then...
my $example = Example->new({
height => 10,
width => 20,
color => 'blue',
});
$example->payload; # { height => 10, width => 20 }
DESCRIPTION
Role::HasPayload::Auto only provides one method, payload
, which returns a hashref of the name and value of every attribute on the object with the Role::HasPayload::Meta::Attribute::Payload trait. (The attribute value is gotten with the the method returned by the attribute's get_read_method
method.)
This role is especially useful when combined with Role::HasMessage::Errf.
