NetSDS::Feature(3pm) User Contributed Perl Documentation NetSDS::Feature(3pm)NAMENetSDS::Feature - abstract application featureSYNOPSISpackage NetSDS::Feature::DBI; use DBI; use base 'NetSDS::Feature'; sub init { my ($self) = @_; my $dsn = $self->conf->{dsn}; my $user = $self->conf->{user}; my $passwd = $self->conf->{passwd}; $self->{dbconn} = DBI->connect($dsn, $user, $passwd); } # Sample method - DBI::do proxy sub do { my $self = shift @_; return $self->{dbconn}->do(@_); } 1;DESCRIPTIONApplication "features" are Perl5 packages with unified API for easy integration of some functionality into NetSDS applications infrastructure. "NetSDS::Feature" module contains superclass for application features providing the following common feature functionality: * class construction * initialization stub * loggingCLASS METHODScreate($app, $conf) - feature constructor init() - feature initialization This method should be rewritten with feature functionality implementation. It's possibly to use application and configuration handlers at this time. Example: sub init { my ($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"); } }OBJECT METHODSapp() - application object This method allows to use application methods and properties. print "Feature included from app: " . $self->app->name; conf() - feature configuration This method provides access to feature configuration. log($level, $message) - implements logging Example: # Write log message $self->log("info", "Application does something interesting."); See NetSDS::Logger documentation for details.EXAMPLESSee "samples/app_features.pl" script.SEE ALSOo NetSDS::AppAUTHORMichael Bochkaryov <misha@rattler.kiev.ua>LICENSECopyright (C) 2008-2009 Net Style Ltd.
