242 Базовый класс для приложений. Использует подход, что приложение
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
243 является объектом, состояние которого предтавляет собой конфигурацию,
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
244 а методы - логику.

diff changeset
245
180
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
246 Данный класс реализует функционал десериализации (и сериализации) экземпляра
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
247 приложения из XML документа. Для этого используется механизм C<IMPL::Serialization>.
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
248 При этом используются опции C<IMPL::Serialization::XmlFormatter> C<IdentOutput> и
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
249 C<SkipWhitespace> для записи документа в легко читаемом виде.

180
d1676be8afcc Перекодировка в utf-8

parents: 179
diff changeset
251 Поскольку в результате восстановления приложения восстанавливаются все элементы
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
252 из файла конфигурации, то это может потребовать значительных ресурсов для
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
253 создания частей, которые могут никогда не понадобиться. Например, не требуется инициализация
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
254 источника данных для передачи пользователю статических данных, сохраненных на диске.
73
wizard
parents: 63
diff changeset
255
180
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
256 Для решения этой проблемы используются специальные объекты C<IMPL::Config::Activator>.
73
wizard
parents: 63
diff changeset
257
180
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
258 Если у приложения описано свойство, в котором хранится C<IMPL::Config::Activator>, то
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
259 при первом обращении к такому свойству, будет создан объект вызовом метода
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
260 C<< IMPL::Config::Activator->activate() >> и возвращен как значение этого свойства.
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
261 Таким образом реализуется прозрачная отложенная активация объектов, что позволяет
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
262 экономить ресурсы.
