Настройка внешнего словаря

Конфигурация словаря имеет следующую структуру:

<dictionary>
    <name>dict_name</name>

    <source>
      <!-- Source configuration -->
    </source>

    <layout>
      <!-- Memory layout configuration -->
    </layout>

    <structure>
      <!-- Complex key configuration -->
    </structure>

    <lifetime>
      <!-- Lifetime of dictionary in memory -->
    </lifetime>
</dictionary>
  • name - Идентификатор, под которым словарь будет доступен для использования. Используйте символы [a-zA-Z0-9_\-].
  • source - Источник словаря.
  • layout - Размещение словаря в памяти.
  • structure - Структура словаря. Ключ и атрибуты, которые можно получить по ключу.
  • lifetime - Периодичность обновления словарей.
