All Implemented Interfaces:

Serializable, org.apache.wicket.extensions.markup.html.repeater.data.sort.ISortStateLocator, org.apache.wicket.extensions.markup.html.repeater.data.table.ISortableDataProvider<T>, org.apache.wicket.IClusterable, org.apache.wicket.markup.repeater.data.IDataProvider<T>, org.apache.wicket.model.IDetachable

public class BufferedSortableDataProvider<T>
extends org.apache.wicket.extensions.markup.html.repeater.util.SortableDataProvider<T>

Buffers the data and performs iterations etc on the Buffered Data instead of being directly connected to some datasource. (Acts as a Decorator to another SortableDataProvider TODO: More work, around Filtering Criteria. Like, its not just about Sub-Sets but Queries etc, how to refresh Buffer with criteria while its still effective to use as a Buffer as a Singleton?! TODO: Cache Count TODO: If query returns no-result, count 0 then only it assumes it should refresh the count. See size(). Need to do it better
