-Паттерн "Абстрактная Фабрика" предоставляет интерфейс для семейств взаимосвязанных объектов без указания их конкретных классов.
-
-Все фабричные паттерны обеспечивают слабую связанность за счет сокращения зависимости приложения от конкретных классов.
-Все фабрики инкапсулируют создание объектов. Абстрактная Фабрика основана на композиции: создание объектов реализуется в методе, доступ к которому осуществляется через интерфейс фабрики. Задача Абстрактной Фабрики - создание семейств взаимосвязанных объектов без зависимости от их конкретных классов.
-
-*Принцип:*
-- По возможности использовать абстракции в коде.
