## BaseArtifactBooter.load() method

Filters the exports of 'discovered' files to only be Classes (in case function / types are exported) as an artifact is a Class. The filtered artifact Classes are saved in the 'classes' property.

NOTE: Booters extending this class should call this method (await super.load()) and then process the artifact classes as appropriate.

**Signature:**

```typescript
load(): Promise<void>;
```
**Returns:**

Promise&lt;void&gt;
