How to handle table selection

Question

In the uix guidelines i found the following example on how to handle table selection:
public static EventResult doSelectionEvent(BajaContext bc, Page page,
PageEvent event)
DataObject tableRows = new PageEventFlattenedDataSet(event, "table1");
int index = SelectionUtils.getSelectedIndex(tableRows);
String name = "Nothing Selected";
// make sure that something was selected:
if (index>=0)
DataObject row = TABLEDATA.getItem(index);
name = row.selectValue(null, "name").toString();
EventResult result = new EventResult(page);
result.setProperty("action", event.getName());
result.setProperty("name", name);
return result;
It is not clear to me what TABLEDATA is.
I read in some other thread that it is a DataObjectList and it represents the 'stored dataObjects'.
I suppose '_TABLE_DATA' is not real code, may i ask for an example with real code to understand what it is?
Thanks.

This code works for me, I hope it is useful.
(NB: i fear you will not read correctly the line
with the getRowAtRangeIndex instruction. It's a problem with the editor).
