Using one of the concrete classes AsyncDataProvider or ListDataProvider whose base class is AbstractDataProvider provides a very efficient mechanism for accessing your widget's underlying data source as well as for manipulating the display of the data itself.
Once a ListDataProvider is setup you can do similar to below:
dataProvider.getList().add(someObjectsList); // add a new SomeObject to the list
sortSomeObjectsList(dataProvider.getList()); // call a method to sort the list
dataProvider.refresh(); // tell all widgets using the data provider to refresh themselves because the data has changed
You can also add & replace lists in a ListDataProvider with:
dataProvider.setList(someObjectsList);
To set up a ListDataProvider:
ListDataProvider<SomeObject> dataProvider = new ListDataProvider<SomeObject>(); // strongly typed declaration - notice the use of type T in the declaration which is the type specifier for the type of objects in the list
dataProvider.setList(someObjectsList); // the list of objects to be provided by the ListDataProvider
dataProvider.addDataDisplay(myCellWidget); // the widget the ListDataProvider is providing the data to

If you want to clear the data first, do the following:myCellTable.setRowCount(0); // Clears all datamyCellTable.setRowCount(20, true); // Set the size of the new datamyCellTable.setRowData(0, myData); // Set the new dataIn GWT 2.1.1, there is a new method CellTable#setRowData(List) that clears all existing data and replaces it with the specified list.Thanks,
