Class SimpleDatasetVaadinAdapter

java.lang.Object

com.whitestein.lsps.vaadin.ui.components.table.adapter.AbstractDatasetVaadinAdapter

com.whitestein.lsps.vaadin.ui.components.table.adapter.SimpleDatasetVaadinAdapter

All Implemented Interfaces:

Serializable

public class SimpleDatasetVaadinAdapter
extends AbstractDatasetVaadinAdapter

A simple adapter which provides its own indexed container and handles sorting/filtering over the container. Does not support user-supplied container type - instead, it provides its own patched IndexedContainer which must be set to the table. You can obtain the container by calling getIndexedContainer().

To use this with a Vaadin table, simply call table.setContainerDataSource(adapter.getIndexedContainer()), then call loadData(int, int) and feed the data obtained to the container.
