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:

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".
