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

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

216 Поскольку в результате восстановления приложения восстанавливаются все элементы
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
217 из файла конфигурации, то это может потребовать значительных ресурсов для
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
218 создания частей, которые могут никогда не понадобиться. Например, не требуется инициализация
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
219 источника данных для передачи пользователю статических данных, сохраненных на диске.

diff changeset
220
180
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
221 Для решения этой проблемы используются специальные объекты C<IMPL::Config::Activator>.

222
180
d1676be8afcc Перекодировка в utf-8
sourcer

223 Если у приложения описано свойство, в котором хранится C<IMPL::Config::Activator>, то
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
224 при первом обращении к такому свойству, будет создан объект вызовом метода
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
225 C<< IMPL::Config::Activator->activate() >> и возвращен как значение этого свойства.
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
226 Таким образом реализуется прозрачная отложенная активация объектов, что позволяет
d1676be8afcc Перекодировка в utf-8
sourcer
parents: 179
diff changeset
227 экономить ресурсы.
