All Known Implementing Classes:

ComponentClassResolverImpl
```
public interface InvalidationListener
```
Deprecated.
In 5.4; use InvalidationEventHub.addInvalidationCallback(Runnable) instead

Interface for objects that may cache information that can be invalidated. Invalidation occurs when external files, from which in-memory data is cached, is determined to have changed. Granularity is very limited; when any external file is found to have changed, the event is fired (with the expectation that the cleared cache will be repopulated as necessary).

5.1.0.0
