POE::Component::Hailo - A non-blocking wrapper around Hailo

SYNOPSIS

 use strict;
 use warnings;
 use POE qw(Component::Hailo);

 POE::Session->create(
     package_states => [
         (__PACKAGE__) => [ qw(_start hailo_learned hailo_replied) ],
     ],
 );

 POE::Kernel->run;

 sub _start {
     POE::Component::Hailo->spawn(
         alias      => 'hailo',
         Hailo_args => {
             storage_class  => 'SQLite',
             brain_resource => 'hailo.sqlite',
         },
     );

     POE::Kernel->post(hailo => learn =>
         ['This is a sentence'],
     );
 }

 sub hailo_learned {
     POE::Kernel->post(hailo => reply => ['This']);
 }

 sub hailo_replied {
     my $reply = $_[ARG0]->[0];
     die "Didn't get a reply" if !defined $reply;
     print "Got reply: $reply\n";
     POE::Kernel->post(hailo => 'shutdown');
 }

DESCRIPTION

POE::Component::Hailo is a POE component that provides a non-blocking wrapper around Hailo. It accepts the events listed under "INPUT" and emits the events listed under "OUTPUT".

METHODS

spawn

This is the constructor. It takes the following arguments:

'alias', an optional alias for the component's session.

'Hailo_args', a hash reference of arguments to pass to Hailo's constructor.

'options', a hash reference of options to pass to POE::Session's constructor.

session_id

Takes no arguments. Returns the POE Session ID of the component.

INPUT

This component reacts to the following POE events:

learn

train

reply

learn_reply

stats

save

All these events take two arguments. The first is an array reference of arguments which will be passed to the Hailo method of the same name. The second (optional) is a hash reference. You'll get this hash reference back with the corresponding event listed under "OUTPUT".

shutdown

Takes no arguments. Terminates the component.

OUTPUT

The component will post the following event to your session:

hailo_learned

hailo_trained

hailo_replied

hailo_learn_replied

hailo_stats

hailo_saved

ARG0 is an array reference of arguments returned by the underlying Hailo method. ARG1 is the context hashref you provided (if any).
