com.inmethod.grid.common.AbstractPageableView<T>

Type Parameters:

T - row/item model object type

All Implemented Interfaces:

Serializable, Iterable<Component>, IEventSink, IEventSource, IFeedbackContributor, IConverterLocator, IMetadataContext<Serializable,Component>, IHeaderContributor, IPageable, IRequestableComponent, IHierarchical<Component>, IClusterable

public abstract class AbstractPageableView<T>
extends RefreshingView<T>
implements IPageable

Wicket AbstractPageableView alternative that uses IDataSource as data source. Compared to Wicket AbstractPageableView this component allows paging without knowing the total number of rows.
