NAME ^

Role::HasPayload::Auto - a thing that automatically computes its payload based on attributes

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.
