Manfred Baedke commented on OAK-343:
------------------------------------
Btw: I admittedly overstretched the contract of the QueryIndex API here, but in
a way that might turn out useful if formalized - as Thomas already pointed out.
Currently the QueryIndexProvider has one single collection of QueryIndexes,
choosing one of them depending on the costs. Alternatively we could have
multiple collections of QueryIndexes which could be combined by logical
operations (As Thomas mentioned, we could also write container QueryIndexes
that combine other QueryIndexes by logical operations. That could be done
without changing the API).

> while adding mix:referenceable to a new node immediately assigns a
> uuid and makes the node referenceable, session.getNodeByUUID only works
> after saving the changes.
> the following test illustrates this behavior:
> @Test
> public void getNodeByUUID() throws RepositoryException {
> Node node = getNode("/foo").addNode("boo");
> node.addMixin(JcrConstants.MIX_REFERENCEABLE);
> assertTrue(node.isNodeType(JcrConstants.MIX_REFERENCEABLE));
> String uuid = node.getUUID();
> assertNotNull(uuid);
> assertEquals(uuid, node.getIdentifier());
> Node nAgain = node.getSession().getNodeByUUID(uuid);
> assertTrue(nAgain.isSame(node));
> assertTrue(nAgain.isSame(node.getSession().getNodeByIdentifier(uuid)));
> }
