Subject [jira] [Commented] (AXIOM-398) Return value of OMNamedInformationItem#getNamespace() should be normalized
Date Sat, 29 Dec 2012 21:58:12 GMT

    [ https://issues.apache.org/jira/browse/AXIOM-398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13541005#comment-13541005

Hudson commented on AXIOM-398:
------------------------------

Integrated in ws-axiom-trunk #1305 (See [https://builds.apache.org/job/ws-axiom-trunk/1305/])
    Code simplification / dead code elimination (OMElement#getNamespace never returns a non
null OMNamespace with an empty namespace URI; see AXIOM-398). (Revision 1426820)

     Result = SUCCESS

> For elements and attributes without namespace, getNamespace() may return two different
values: null or an OMNamespace instance that has both prefix and namespaceURI properties set
to the empty string. The value that is actually returned in this case depends in subtle ways
on how the information item was created. This can be illustrated by the following code snippet:
> OMElement element1 = AXIOMUtil.stringToOM("<root/>");
> System.out.println(element1.getNamespace());
> OMElement element2 = AXIOMUtil.stringToOM("<root xmlns=''/>");
> System.out.println(element2.getNamespace());
> The output is:
> null
> org.apache.axiom.om.impl.common.OMNamespaceImpl@0
> One can see that although the two elements are equivalent, the return value of getNamespace()
is different.
> The return value of getNamespace() should be normalized such that it is always the same
(i.e. null) for information items without namespace.
