	 * To use this method, simply override it to perform work on each item passed in.  Due to
	 * supporting backward compatibility, clients still have to implement
	 * {@link #execute(AddressableRowObject)}.  When using
	 * {@link #executeInBulk(List, List, TaskMonitor)}, simply implement
	 * {@link #execute(AddressableRowObject)} as a do-nothing method.
	 * <p>
	 * You are responsible for checking the cancelled state of the task monitor by calling
	 * {@link TaskMonitor#isCancelled()}.  This allows long-running operations to be cancelled.  You
	 * should also call {@link TaskMonitor#incrementProgress(long)} as you process each item in
	 * order to show progress in the UI.
	 * <p>
	 * Note: the {@link #execute(AddressableRowObject)} method is only called with items that are
	 * still in the dialog's table model.  Some clients may programmatically manipulate the table
	 * model by removing row objects via the dialog's add/remove methods. The
	 * {@link #execute(AddressableRowObject)} method is only called for items that still exist in
	 * the model.  Contrastingly, this version of execute offers no such protection.  Thus, if you
	 * manipulate the table model yourself, you also need to ensure that any items you process in
	 * this method are still in the dialog.  To see if the item is still in the dialog, call
	 * {@link TableChooserDialog#contains(AddressableRowObject)}.
	 *
	 * @param rowObjects the objects to be processed
	 * @param deleted place any items to be removed from the table into this list
	 * @param monitor the task monitor

	 * 	       you override it
