## SubDocument class


Represents a **SubDocument** - which is a reference to an externally stored document. To learn more, visit the [Aspose.Words Document Object Model (DOM)](https://docs.aspose.com/words/cpp/aspose-words-document-object-model/) documentation article.

```cpp
class SubDocument : public Aspose::Words::Node
```

| virtual [get_Document](../node/get_document/)() const | Gets the document to which this node belongs. |
| virtual [get_IsComposite](../node/get_iscomposite/)() | Returns **true** if this node can contain other nodes. |
| [get_NextNode](../node/get_nextnode/)() const |  |
| [get_NextSibling](../node/get_nextsibling/)() | Gets the node immediately following this node. |
| [get_NodeType](./get_nodetype/)() const override | Returns [SubDocument](../nodetype/). |
| [get_ParentNode](../node/get_parentnode/)() | Gets the immediate parent of this node. |
| [get_PreviousSibling](../node/get_previoussibling/)() | Gets the node immediately preceding this node. |
| [get_PrevNode](../node/get_prevnode/)() const |  |
| [get_Range](../node/get_range/)() | Returns a [Range](../range/) object that represents the portion of a document that is contained in this node. |
| [GetAncestor](../node/getancestor/)(Aspose::Words::NodeType) | Gets the first ancestor of the specified [NodeType](../nodetype/). |
| [GetAncestorOf](../node/getancestorof/)() |  |
| virtual [GetText](../node/gettext/)() | Gets the text of this node and of all its children. |
| [GetType](./gettype/)() const override |  |
| [Is](./is/)(const System::TypeInfo\&) const override |  |
| [IsAncestorNode](../node/isancestornode/)(const System::SharedPtr\<Aspose::Words::Node\>\&) |  |
| [NextPreOrder](../node/nextpreorder/)(const System::SharedPtr\<Aspose::Words::Node\>\&) | Gets next node according to the pre-order tree traversal algorithm. |
| static [NodeTypeToString](../node/nodetypetostring/)(Aspose::Words::NodeType) | A utility method that converts a node type enum value into a user friendly string. |
| [PreviousPreOrder](../node/previouspreorder/)(const System::SharedPtr\<Aspose::Words::Node\>\&) | Gets the previous node according to the pre-order tree traversal algorithm. |
| [Remove](../node/remove/)() | Removes itself from the parent. |
| [set_CustomNodeId](../node/set_customnodeid/)(int32_t) | Setter for [Aspose::Words::Node::get_CustomNodeId](../node/get_customnodeid/). |
| [set_NextNode](../node/set_nextnode/)(const System::SharedPtr\<Aspose::Words::Node\>\&) |  |
| [set_PrevNode](../node/set_prevnode/)(const System::SharedPtr\<Aspose::Words::Node\>\&) |  |
| [SetParent](../node/setparent/)(const System::SharedPtr\<Aspose::Words::Node\>\&) |  |
| [ToString](../node/tostring/)(Aspose::Words::SaveFormat) | Exports the content of the node into a string in the specified format. |
| [ToString](../node/tostring/)(const System::SharedPtr\<Aspose::Words::Saving::SaveOptions\>\&) | Exports the content of the node into a string using the specified save options. |
| static [Type](./type/)() |  |
## Remarks


In this version of Aspose.Words, [SubDocument](./) nodes do not provide public methods and properties to create or modify a subdocument. In this version you are not able to instantiate [SubDocument](./) nodes or modify existing except deleting them.

[SubDocument](./) can only be a child of [Paragraph](../paragraph/).

## Examples



Shows how to access a master document's subdocument. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>(System::String(get_MyDir() + u"Master document.docx"));

System::SharedPtr<Aspose::Words::NodeCollection> subDocuments = doc->GetChildNodes(NodeType::SubDocument, true);

// This node serves as a reference to an external document, and its contents cannot be accessed.
auto subDocument = System::ExplicitCast<Aspose::Words::SubDocument>(subDocuments->idx_get(0));

ASSERT_FALSE(subDocument->get_IsComposite());
```
