# MTLComputePipelineReflection

Information about the arguments of a compute function.

```
class MTLComputePipelineReflection
```

## Overview

An [`MTLComputePipelineReflection`](/documentation/Metal/MTLComputePipelineReflection) object provides access to the arguments of the compute function used in an [`MTLComputePipelineState`](/documentation/Metal/MTLComputePipelineState) object. An [`MTLComputePipelineReflection`](/documentation/Metal/MTLComputePipelineReflection) object can be created along with an [`MTLComputePipelineState`](/documentation/Metal/MTLComputePipelineState) object. Don’t create an [`MTLComputePipelineReflection`](/documentation/Metal/MTLComputePipelineReflection) object directly. Instead, call either the [`makeComputePipelineState(function:options:reflection:)`](/documentation/Metal/MTLDevice/makeComputePipelineState(function:options:reflection:)) or [`makeComputePipelineState(function:options:completionHandler:)`](/documentation/Metal/MTLDevice/makeComputePipelineState(function:options:completionHandler:)) method of [`MTLDevice`](/documentation/Metal/MTLDevice) to create both an [`MTLComputePipelineState`](/documentation/Metal/MTLComputePipelineState) object and an [`MTLComputePipelineReflection`](/documentation/Metal/MTLComputePipelineReflection) object.

[`MTLComputePipelineReflection`](/documentation/Metal/MTLComputePipelineReflection) objects can use a significant amount of memory; release any strong references to them after you finish creating pipeline objects.
