# elementTextureReferenceType()

Provides a description of the underlying texture type when an array holds textures as its elements.

```
func elementTextureReferenceType() -> MTLTextureReferenceType?
```

## Return Value

An object that describes the texture. If the array elements aren’t textures, this method returns `nil`.

## Discussion

Use this method if [`elementType`](/documentation/Metal/MTLArrayType/elementType) is [`MTLDataType.texture`](/documentation/Metal/MTLDataType/texture).
