# MTLArrayType

A description of an array.

## Declaration

```swift
class MTLArrayType
```

## Overview

Overview An MTLArrayType instance provides details about an array parameter. Don’t create MTLArrayType instances directly; other reflection instances contain properties to determine if a parameter is an array and to obtain the MTLArrayType instance that describes the array.
