Immediately call `balb::FileCleanerUtil::removeFiles` with the specified `config` and then install an `t_OBSERVER::OnFileRotationCallback` function into the specified `observer` that invokes `removeFiles` synchronously on every log file rotation. The (template parameter) `t_OBSERVER` type must provide concrete implementation of the `ball::Observer` protocol, have a `setOnFileRotationCallback` method (see `ball_fileobserver`, `ball_fileobserver2`, and `ball_asyncfileobserver`), and define an `OnFileRotationCallback` type alias. This method overrides the file rotation callback currently installed in the observer (if any).
