## NodeCollection class


Представляет коллекцию узлов определённого типа. Чтобы узнать больше, посетите статью документации [Aspose.Words Document Object Model (DOM)](https://docs.aspose.com/words/cpp/aspose-words-document-object-model/).

```cpp
class NodeCollection : public Aspose::Words::INodeCollection,
                       public System::Collections::Generic::IEnumerable<System::SharedPtr<Aspose::Words::Node>>
```

## Методы

| Метод | Описание |
| --- | --- |
| [Add](./add/)(const System::SharedPtr\<Aspose::Words::Node\>\&) | Добавляет узел в конец коллекции. |
| [Clear](./clear/)() | Удаляет все узлы из этой коллекции и из документа. |
| [Contains](./contains/)(const System::SharedPtr\<Aspose::Words::Node\>\&) | Определяет, находится ли узел в коллекции. |
| [get_Count](./get_count/)() | Получает количество узлов в коллекции. |
| [GetEnumerator](./getenumerator/)() override | Предоставляет простую итерацию в стиле "foreach" по коллекции узлов. |
| [GetType](./gettype/)() const override |  |
| [idx_get](./idx_get/)(int32_t) | Получает узел по заданному индексу. |
| [IndexOf](./indexof/)(const System::SharedPtr\<Aspose::Words::Node\>\&) | Возвращает нулевой индекс указанного узла. |
| [Insert](./insert/)(int32_t, const System::SharedPtr\<Aspose::Words::Node\>\&) | Вставляет узел в коллекцию по указанному индексу. |
| [Is](./is/)(const System::TypeInfo\&) const override |  |
| [Remove](./remove/)(const System::SharedPtr\<Aspose::Words::Node\>\&) | Удаляет узел из коллекции и из документа. |
| [RemoveAt](./removeat/)(int32_t) | Удаляет узел по указанному индексу из коллекции и из документа. |
| [ToArray](./toarray/)() | Копирует все узлы из коллекции в новый массив узлов. |
| static [Type](./type/)() |  |
## Примечания


[NodeCollection](./) does not own the nodes it contains, rather, is just a selection of nodes of the specified type, but the nodes are stored in the tree under their respective parent nodes.

[NodeCollection](./) supports indexed access, iteration and provides add and remove methods.

Коллекция [NodeCollection](./) является «живой», т.е. изменения дочерних элементов объекта узла, из которого она была создана, немедленно отражаются в узлах, возвращаемых свойствами и методами [NodeCollection](./).

[NodeCollection](./) is returned by [GetChildNodes()](../compositenode/getchildnodes/) and also serves as a base class for typed node collections such as [SectionCollection](../sectioncollection/), [ParagraphCollection](../paragraphcollection/) etc.

[NodeCollection](./) can be "flat" and contain only immediate children of the node it was created from, or it can be "deep" and contain all descendant children.

```cpp
