Vaadin 8 IndexedContainer

Migrating from a Vaadin 7.7.7 project to Vaadin 8, I found at the vaadin 8 documentation, that the IndexedContainer is no longer part of the vaadin API. What should I use instead for my Grid? I’ll appreciate a little use example.

[code]
import com.vaadin.data.util.IndexedContainer; //Cannot be resolved

IndexedContainer GridContainer= new IndexedContainer(); //Cannot be resolved to a type
GridContaineraddContainerProperty(“HoraTerminada”, String.class, “”);
GridContainer.addContainerProperty(“DescripciondeTrabajo”, String.class, “”);

grid = new Grid(GridContainerReporte);
[/code]Many thanks.

*grid = new Grid(GridContainer);
