jQuery Forum

You could stick it on the jQuery namespace and call it a jQuery plugin, but in reality it doesn't need jQuery, so there's no reason to restrict it to only be used with jQuery.

In the source of the function Class you can specify an "host" as namespace; i am using window now, everyone can replace it with $.
Anyway you'll get the global variable InheritanceApi object as well.
When i wrote " i' ll be happy if someone will make a jQuery plugin of it " i was thinking about something cleaner.
Ii've never seen a plugin written in this way:

var myPluginDependences = {}; // global
$.myPlugin = function(){
    // implementation using myPluginDependences
};

but always:

(function($){
    $.fn.pluginName = function(options) {
        // ...
    };
})(jQuery);

Anyway the result is not bad!
Could be better, following this way, to change the host in all modules (but not int the Class one) from window to a not global var and the host for the Class function to $ .
But i am not sure it will work without any errors...

the $.fn.pluginName = function signature is for creating plugins that need a DOM Node to work. In your case you are defining a class which may not need a DOM Node, therefore if you are to add it to the jQuery namespace, the best place to do it would be directly on $ unless you want your plugin to require a selected element.
