Re: [Vala] Simple Memory Management Issue

I was able to work around it. Basically I never wanted the interface
to be called but the object implementing the interface. Only problem
is, its an unknown class at runtime. So I have no way of knowing how
to describe the object as a hash map.

var plugins = new Gee.HashMap<string, PlugPlug> ();

PlugPlug was the interface, not object. So when I loaded the object
after putting it into the hash map it would resolve to the interface's
run and not the object's run.

So instead I just used the registrars:
var plugins = new Gee.HashMap<string, PluginRegistrar> ();

Which changes the code to:
var has_plugin = plugins.has_key (choice);
if (!has_plugin) {
        var registrar = new PluginRegistrar<PlugPlug> (choice);
        var loaded = registrar.load ();
        if (loaded) {
                plugins[choice] = registrar;
                has_plugin = true;
        }
}
if (has_plugin) {
        var plugin = ((PluginRegistrar<PlugPlug>) plugins[choice]).new_object ();
        plugin.run (items);
}

In result it creates a new object every time but at least it works :\.
