Is it posible multiple Inheritance?

[buda]

I need to create class which is inhereted from enumerable module,
sortable class and observable class
Is it possible in one operation call?

[Andrew Dupont]

Sadly, no. You can mixin any number of objects (like Enumerable), but
only one class.

Hi Andrew!

is it possible to realize extending of the class by in a way that at the end of this process would be called the initialization method of extension?

So I would be extend any class with such extensions with no need to create intermediate classes.

Often in such extension I need to add some properties to extended object and need to initialiaze them - initialization of extension would be the nice idea!

Just use Object.extend()

var MyClass = Class.create();
Object.extend(MyClass.prototype, Enumerable);
Object.extend(MyClass.prototype, Sortable.prototype);
Object.extend(MyClass.prototype, Observable.prototype);

Object.extend(MyClass.prototype, {
// your methods
doSomething: function() ...
});
