Question about root node children?
Hi,
As you know, I am still fairly new to Jackrabbit and its internals. I think
there is something I didn't understand correctly. Can you please help me?
I am trying to fetch all direct children of the root node from a repository
with 3 nodes I have put in. When I write root.getChildNodeEntries(); I have
a List with 170 elements in it! When I display their QName, there are only
5 differnent QNames as expected (my 3 nodes + root + jcr:system).
What am I doing wrong please?
BR,
Nico

Hi Jukka,
Thanks, you are totally right.
(for the little story, it comes from a temporary unit test.)

You've probably run code like the following a few times over:
Session session = ...;
Node root = session.getRootNode();
root.addNode("A");
root.addNode("B");
root.addNode("C");
session.save();
When run multiple times, this results in a repository like this:
/
/jcr:system
/A[1]
/A[2]
/A[...]
/B[1]
/B[2]
/B[...]
/C[1]
/C[2]
/C[...]

Actually they have different names, but the same name sibling is a use case
I should be taking care of.
Do you have an idea why with same name sibling this behaviour happens?

just a wild guess, you are using same name siblings?

Hi Szymon,
Rereading my email, there is something important I forgot to write: the
snippet of code is the following:
itemOps = new a BatchedItemOperations(...);
NodeState root = itemOps.getNodeState(nodeInfo.getId());
root.getChildNodeEntries();
As you can see root is not an instance of Node but of NodeState. Maybe it
would help you to explain things better?

if You would like to fetch children, I think the better way will be to
use getNodes() method on root node, because getChildNodeEntries()
returns list of node entries, not nodes. This will return NodeIterator,
so You will be able to iterate over all children.
Hope this will help.

Simon
