    -port             => 9505,
    -host             => 'localhost',
    -filter           => POE::Filter::Line->new(),
    -alias            => 'server',

DESCRIPTION

This module implements a simple text orientated network protocol. Data is sent out as delimited strings. Which means every string has a consistent EOL. These strings may be formatted, such as JSON. This module inherits from XAS::Lib::POE::Session.

This initializes the module and starts listening for requests. There are five parameters that can be passed. They are the following:

-alias

The name of the POE session.

-port

The IP port to listen on.

-address

The address to bind too.

-inactivity_timer

Sets an inactivity timer on clients. When it is surpassed, the method reaper() is called with the POE wheel id. What reaper() does is application specific. The default is 600 seconds.

-filter

An optional filter to use, defaults to POE::Filter::Line

-eol

An optional EOL, defaults to "\015\012";

reaper($wheel)

Called when the inactivity timer is triggered.

$wheel

The POE wheel that triggered the timer.

This method will process the input from the client. It takes the following parameters:

$input

The input received from the socket.

process_response($output, $ctx)

This method will process the output for the client. It takes the following parameters:

$output

$wheel

The id of the clients wheel.
