-/**
- * Neatly scope a transactional operation. To use, a subclass of RunnableTransaction should be
- * provided which implements any one of the three flavors of the body method.
- * The default implementations pass control from most specific to least specific -- that is,
- * from {@link #body(Storable)} to {@link #body()} -- so the
- * implementor is free to override whichever makes the most sense.
- *
- * <P>A typical use pattern would be:
- *
- * <pre>
- * RunnableTransaction rt = new RunnableTransaction(repository) {
- * public void body() throws PersistException {
- * for (Storable s : someFieldContainingStorables) {
- * s.insert();
- * }
- * };
- * rt.run();
- * </pre>
