Jifty::Plugin::ClassLoader - Automatically generates application classes
Jifty::Plugin::ClassLoader loads additional model and action classes on behalf of the application out of the configured plugin classes. Unlike, Jifty::ClassLoader, this class will only autogenerate classes if the plugin provides them. The plugin classes are checked before the base Jifty classes, so that a plugin can override the Jifty class, just as any existing application classes will be loaded first.
Jifty::Plugin::ClassLoader
Jifty::ClassLoader
Returns a new ClassLoader object. Doing this installs a hook into @INC that allows Jifty::Plugin::ClassLoader to dynamically create needed classes if they do not exist already. This works because if use/require encounters a blessed reference in @INC, it will invoke the INC method with the name of the module it is searching for on the reference.
@INC
Takes two mandatory arguments, base, which should be the application's base path; and plugin which is the plugin classname.
base
plugin
The hook that is called when a module has been require'd that cannot be found on disk. The following stub classes are auto-generated:
require
An empty application base class is created that doesn't provide any methods or inherit from anything.
An empty class that descends from Jifty::Record is created.
An empty class that descends from Jifty::Collection is created.
An empty class that descends from Jifty::Notification.
An empty class that descends from Jifty::Dispatcher.
An empty class that descends from Jifty::Bootstrap.
An empty class that descends from Jifty::Upgrade.
An empty class that descends from Jifty::CurrentUser.
If Application::Model::Something is a valid model class, then it creates a subclass of Jifty::Collection whose record_class is Application::Model::Something.
Application::Model::Something
record_class
If Application::Model::Something is a valid model class, then it creates a subclass of Jifty::Action::Record::Create, Jifty::Action::Record::Update, or Jifty::Action::Record::Delete whose record_class is Application::Model::Something.
Loads all of the application's Actions and Models. It additionally require's all Collections and Create/Update actions for each Model base class -- which will auto-create them using the above code if they do not exist on disk.
When the ClassLoader gets garbage-collected, its entry in @INC needs to be removed.
