public void extendClassPath(String newPathElement)
```
  - getDexClassPathExtensions
```
public Set<String> getDexClassPathExtensions()
```

```
    Clears the set of dex or apk or assembly files that still need to be indexed
  - resetCaches
```
public void resetCaches()
```
    Resets the cached class path, class providers, and source path to null. This method allows for subsequent calls to Scene.loadNecessaryClasses() to recompute and load the classes using updated configurations if provided.
