NetSDS::Feature - abstract application feature
package 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 $self->{dbconn}->do(@_); } 1;
Application features are Perl5 packages with unified API for easy integration of some functionality into NetSDS applications infrastructure.
features
NetSDS::Feature module contains superclass for application features providing the following common feature functionality:
NetSDS::Feature
* class construction * initialization stub * logging
This method should be rewritten with feature functionality implementation. It's possibly to use application and configuration handlers at this time.
Example:
sub init { my ($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"); } }
This method allows to use application methods and properties.
print "Feature included from app: " . $self->app->name;
This method provides access to feature configuration.
# Write log message $self->log("info", "Application does something interesting.");
See NetSDS::Logger documentation for details.
See samples/app_features.pl script.
