/**
* {@link Beta}
* Callback to receive unparsed notifications for watched resource.
*
* Must NOT be implemented in form of an anonymous class since this would break serialization.
*
*
Should be thread-safe as several notifications might be processed at the same time. Example
* usage:
*
*
* static class MyNotificationCallback implements UnparsedNotificationCallback {
*
* private static final long serialVersionUID = 1L;
*
* {@literal @}Override
* public void onNotification(StoredChannel storedChannel, UnparsedNotification notification) {
* String contentType = notification.getContentType();
* InputStream contentStream = notification.getContentStream();
* switch (notification.getResourceState()) {
* case ResourceStates.SYNC:
* break;
* case ResourceStates.EXISTS:
* break;
* case ResourceStates.NOT_EXISTS:
* break;
* }
* }
* }
