SYNOPSIS

my $server = XAS::Lib::Net::Server->new(
    -port             => 9505,
    -address          => 'localhost',
    -filter           => POE::Filter::Line->new(),
    -alias            => 'server',

DESCRIPTION

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

METHODS

new

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 "\012\015";

reaper($wheel)

Called when the inactivity timer is triggered.

$wheel

The POE wheel that triggered the timer.
