RelatedNodesSelector (PMD Core 6.23.0 API)

```
@Experimental
public interface RelatedNodesSelector
```
Provides a way for the designer to highlight related nodes upon selection, eg those nodes referring to the same variable or method.
This API only published to bind to the designer for now, it should not be used by rule code. The criterion for selecting nodes to highlight is subject to change at the implementation's discretion. In particular it's not necessarily the usages of a variable.
The binary API is unstable until at least 7.0, meaning the only place this can be implemented safely is within PMD's own codebase.

Since:

6.20.0
