# CLSActivityItem

An abstract base class for gathering information about an activity.

## Declaration

```swift
class CLSActivityItem
```

## Overview

Overview You don’t typically use an instance of this class directly. Instead, use one of its subclasses to represent a particular activity metric. For example, use a CLSScoreItem to add a score to a CLSContextType.quiz activity.
