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

BindingInterfacePrivate =
	new: (stage, object)-> new BindingInterface(@_, stage, @, object)

		@_ = binding
		Object.defineProperties @,
			'ID':			get: ()-> binding.ID
			'value':		get: ()-> binding.value
			'original':		get: ()-> binding.objects or binding.object
			'dependents':	get: ()-> binding.deps.slice().map (dep)-> dep.object
			'lastProxied':	get: ()-> @proxies[@proxies.length-1]




	createBinding: (subject, newObjectType, isSimpleObject, isProxiedFunc, bindingInterface)->
		@object = subject
		cachedBinding = cache.get(subject, isSimpleObject, @selector, @isMultiChoice)
		
		if cachedBinding # Exit early by returning the subject from cache if is already in there
			return @patchCachedBinding(cachedBinding)

		else
			newBinding = new Binding(subject, newObjectType, bindingInterface or @, isProxiedFunc)
			cache.set(newBinding, isSimpleObject)
			return newBinding



	patchCachedBinding: (cachedBinding)->
		cachedBinding.placeholder = @placeholder
		
		if @placeholder and not cachedBinding.pholderValues # A cached version with no placeholders set exists - needs scanning
			cachedBinding.valueOriginal = cachedBinding.fetchDirectValue()
			cachedBinding.scanForPholders()

		if cachedBinding.type is 'ObjectProp' and @property not of @object # This property was manually deleted and needs its prop to be re-defined as a live one
			cachedBinding.makePropertyLive(true)

		setOptionsForBinding(cachedBinding, @optionsPassed)
