All Known Implementing Classes:

ComponentDependencyRegistryImpl
```
public interface ComponentDependencyRegistry
```
Internal service that registers direct dependencies between components (including components, pages and base classes). Even though methods receive ComponentPageElement parameters, dependencies are tracked using their fully qualified classs names.

Since:

5.8.3
