InfiniteDataView (Gwt Material Table 2.0 API)

java.lang.Object
- gwt.material.design.client.data.AbstractDataView<T>
- - gwt.material.design.client.data.infinite.InfiniteDataView<T>

All Implemented Interfaces:

com.google.gwt.event.shared.HasHandlers, com.google.gwt.view.client.HasKeyProvider<T>, DataView<T>, HasCategories, HasColumns<T>, HasDataSource<T>, HasRenderer<T>, HasRows<T>, HasLoader, ViewSettings
```
public class InfiniteDataView<T>
extends AbstractDataView<T>
implements HasLoader
```
The InfiniteDataView is designed for lazy loading data, while using minimal DOM row elements.
The data source will invoke a load when the view index changes on scrolling.

How to use:
- View size can be configured manually or can be set to dynamic view using DYNAMIC_VIEW.
- Provide a valid DataSource implementation.
