Subject [jira] [Commented] (OAK-169) Support orderable nodes
Date Tue, 10 Jul 2012 09:34:33 GMT

    [ https://issues.apache.org/jira/browse/OAK-169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13410174#comment-13410174

Michael Dürig commented on OAK-169:
-----------------------------------

Support for (efficient) stable order would require support from the Microkernel. But exactly
this was removed in [Revision 1234198|http://svn.apache.org/viewvc/jackrabbit/oak/trunk/oak-mk/src/main/java/org/apache/jackrabbit/mk/model/ChildNodeEntriesMap.java?r1=1234021&r2=1234198&diff_format=h]
in order to support large child node lists. So I suggest we stay with this for now and use
the multi valued property if we need a stable order and/or orderability.

> There are JCR clients that depend on the ability to explicitly specify the order of child
nodes. That functionality is not included in the MicroKernel tree model, so we need to implement
it either in oak-core or oak-jcr using something like an extra (hidden) {{oak:childOrder}}
property that records the specified ordering of child nodes. A multi-valued string property
is probably good enough for this.
