/**
* {@link Beta}
* A {@link TypedNotificationCallback} which uses a JSON content encoding with {@link
* GsonFactory#getDefaultInstance()}.
*
* Must NOT be implemented in form of an anonymous class as this will break serialization.
*
*
Implementation should be thread-safe. Example usage:
*
*
{@code
* static class MyNotificationCallback
* extends JacksonNotificationCallback{@literal <}ListResponse{@literal >} {
*
* private static final long serialVersionUID = 1L;
*
* {@literal @}Override
* protected void onNotification(StoredChannel channel,
* TypedNotification{@literal <}ListResponse{@literal >} notification) {
* ListResponse content = notification.getContent();
* switch (notification.getResourceState()) {
* case ResourceStates.SYNC:
* break;
* case ResourceStates.EXISTS:
* break;
* case ResourceStates.NOT_EXISTS:
* break;
* }
* }
*
* {@literal @}Override
* protected Class{@literal <}ListResponse{@literal >} getDataClass() throws IOException {
* return ListResponse.class;
* }
* }
* }
*
* @param Type of the data contained within a notification
