  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).
