| 209 | 55 =head1 NAME |
| 56 | |
| 57 C<IMPL::Class::PropertyInfo> - метаданные о свойствах объектов. Используются для отражения и | |
| 58 проверки данных объектов. | |
| 59 | |
| 60 =head1 DESCRIPTION | |
| 61 | |
| 62 В зависимости от типа каждый объект предоставляет способ хранения данных, например хеши позволяют | |
| 63 хранить состояние в виде ассоциативного массива и т.д. Информация о свойстве предоставляет определенный | |
| 64 уровень абстракции. | |
