IOC::Service::Literal - An IOC Service object whose component is a literal value
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();
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.
+--------------+ | IOC::Service | +--------------+ | ^ | +-----------------------+ +-----------------+ | IOC::Service::Literal |---(instance)--->| <Literal Value> | +-----------------------+ +-----------------+
Creates a service with a $name, and uses the $literal value which need not be initialized.
$name
$literal
Returns the name of the service instance.
This is a no-op method, since the service is not initialized, then it does not need an instance of the container.
This is a no-op method, see setContainer above.
setContainer
This method returns the literal value held by the service object.
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
I use Devel::Cover to test the code coverage of my tests, see the CODE COVERAGE section of IOC for more information.
