@Stable
public interface RandomOffset
extends java.io.Serializable

An interface representing offset for paging. This interface is needed because various db engines can have different notion of ordering and therefore it might be difficult to do paging based simply on the key (of entity or attribute). Simple example is a hash map, where you cannot page through the map based on the key stored in the map. This is just a labeling interface.
