# MTLIndirectRenderCommand

A render command in an indirect command buffer.

## Declaration

```swift
protocol MTLIndirectRenderCommand : NSObjectProtocol
```

## Overview

Overview Don’t implement this protocol; you get instances of this type by asking an MTLIndirectCommandBuffer for them. Use this instance to reset or encode a command. You need to reset a command before encoding a new command.

## Topics

### Setting command arguments
