# MTLRenderPipelineReflection

Information about the arguments of a graphics function.

## Declaration

```swift
class MTLRenderPipelineReflection
```

## Overview

Overview The MTLRenderPipelineReflection class is an interface that represents the parameters for the shaders in a render pipeline state (see MTLRenderPipelineState). Each pipeline state can include object, mesh, vertex, fragment, and tile shaders. You create a reflection instance at the same time as the pipeline state that it represents by calling the appropriate MTLDevice method. For example, the makeRenderPipelineState(descriptor:options:reflection:) and makeRenderPipelineState(descriptor:options:completionHandler:) methods create the pipeline state and the reflection instances at the same time. important: Only create reflection instances if you need them because each one can require a significant amount of memory. For more information, see Pipeline state creation.
