my $server = XAS::Lib::Net::Server->new(
-port => 9505,

-filter => POE::Filter::Line->new(),
-alias => 'server',
-inactivity_timer => 600,
-eol => "\015\012"

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.
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.

An optional filter to use, defaults to POE::Filter::Line
- -eol
-
An optional EOL, defaults to "\015\012";
