* **Assembly:** UnityEngine.UIElementsModule
* **Inherits from:** [UxmlFactory\<VisualElement, UxmlRootElementTraits>](/engine/6000.3/script-reference/unityengine/uielements/uxmlfactory2.md)
* **Implements:** [IUxmlFactory](/engine/6000.3/script-reference/unityengine/uielements/iuxmlfactory.md), [IBaseUxmlFactory](/engine/6000.3/script-reference/unityengine/uielements/ibaseuxmlfactory.md)

> **Warning:**

```csharp
public class UxmlRootElementFactory : UxmlFactory<VisualElement, UxmlRootElementTraits>, IUxmlFactory, IBaseUxmlFactory
```

## Remarks

This factory does not generate VisualElements. UIElements uses it to generate schemas.
