NAME

IOC::Service::Literal - An IOC Service object whose component is a literal value

CONTENTS

SYNOPSIS



  use IOC::Service::Literal;
 
  my $container = IOC::Container->new();
  # use a literal here for our log_file
  $container->register(IOC::Service::Literal->new(log_file => "logfile.log" ));
  $container->register(IOC::Service->new(logger => sub {
      my $c = shift;
      return FileLogger->new($c->get(log_file));
  }));
  $container->register(IOC::Service->new(application => sub {
      my $c = shift;
      my $app = Application->new();
      $app->logger($c->get(logger));
      return $app;
  }));

  $container->get(application)->run();



DESCRIPTION

In this IOC framework, the IOC::Service::Literal object holds a literal value which does not need to be initialized. This IOC::Service subclass is specifically optimized to handle values which need no initialization, like literal values, such as numbers and strings. It is sometimes useful for these types of values to be included in your configuration, this helps reduce the overhead for them.

METHODS

<B>new ($name, B>$literal<B>)B> Creates a service with a $name, and uses the $literal value which need not be initialized.
<B>nameB> Returns the name of the service instance.
<B>setContainer ($container)B> This is a no-op method, since the service is not initialized, then it does not need an instance of the container.
<B>removeContainerB> This is a no-op method, see setContainer above.
<B>instanceB> This method returns the literal value held by the service object.
