Application \*(C`features\*(C' are Perl5 packages with unified \s-1API\s0 for easy integration of some functionality into NetSDS applications infrastructure.

\*(C`NetSDS::Feature\*(C' module contains superclass for application features providing the following common feature functionality:

* class construction * initialization stub * logging

init() - feature initialization

This method should be rewritten with feature functionality implementation. It's possibly to use application and configuration handlers at this time. Example: sub init { my ($self) = @_;

$self->{answer} = $self->conf->{answer} || '42';

my $pid = $self->app->pid();

if ($self->app->daemon()) { $self->log("info", "Seems we are in a daemon mode"); } }

app() - application object

This method allows to use application methods and properties. print "Feature included from app: " . $self->app->name;

conf() - feature configuration

This method provides access to feature configuration. Example: # Write log message $self->log("info", "Application does something interesting."); See NetSDS::Logger documentation for details.

See \*(C`samples/app_features.pl\*(C' script.
