Get selected rows of ADF Table

Assuming you expose a binding (called 'resultTable') of the table component in a managed bean:
For multiple row selection (assuming a RichTable reference called myDataTable, based on a collection of MyObject objects):

// get the selected rows from a table component  
public void getMultipleRows(ActionEvent actionEvent) {
     RichTable table = getMyDataTable();
       for (Object facesRowKey : table.getSelectedRowKeys()) {
            table.setRowKey(facesRowKey);
            Object o = table.getRowData();
            MyObject selectedItem = (MyObject)o;
            if (selectedItem != null) {
                 // process the item
       }
   }
}

For single selection:

public Object getSelectedRow(RichTable table) {
   Object _selectedRowData = table.getSelectedRowData();
   JUCtrlHierNodeBinding _nodeBinding = (JUCtrlHierNodeBinding)_selectedRowData;
   return _nodeBinding.getRow();
}

So we can define a Selection Listener for the table, and this way we can get the source table component from the event itself:

// to get the selected Rows 
public void itemSelected(SelectionEvent selectionEvent) {
     RichTable table = (RichTable)selectionEvent.getSource();
     DCDataRow dcrow = (DCDataRow)getSelectedRow(table);
     MyObject selectedItem = (MyObject)dcrow.getDataProvider();
     // TODO ...
}

If the table is backed by a View Object, we can cast the selected row to a ViewRowImpl object:

public void itemSelected(SelectionEvent selectionEvent) {
     RichTable table = (RichTable)selectionEvent.getSource();
     ViewRowImpl row = (ViewRowImpl)getSelectedRow(table);
     if (row != null) {
        String attr1 = (String)row.getAttribute("attr1");
        String attr2 = (String)row.getAttribute("attr2");
        // ...
   }
}
