Magically simple, framework-less one-way/two-way data binding for frontend/backend in ~5kb.

GroupBinding = (bindingInterface, objects, objectType)->
	bindingInterface.selector = bindingInterface.selector.slice(6) # Take out the 'multi:'
	extendState(@, @interface = bindingInterface)
	@isMulti = true
	@bindings = bindings = []

	if objects
		@addBinding(object, objectType) for object in objects

	Object.defineProperties @,
		'type':				get: ()-> bindings.map (binding)-> binding.type
		'value': 			get: ()-> bindings.map (binding)-> binding.value






proto = GroupBinding:: = Object.create(BindingInterfacePrivate)

Object.keys(Binding::).forEach (methodName)->	
	proto[methodName] = (a,b,c,d)-> # Four arguments is the most ever passed to any method from BindingInterface methods
		for binding in @bindings
			b = binding if methodName is 'updateSub'
			binding[methodName](a,b,c,d)
		
		return


proto.addBinding = (object, objectType)->
	@bindings.push if not objectType then object else @createBinding(object, objectType, @interface)
	return
