Hello,
i programmed a class /Node/ which is here used as /n/ and a class /NodeType/
which is reference by Node. In the ClassBuilder from Node i use this method
to get the NodeType
try {
List<XWikiDocument> docs =
getXWikiContext().getWiki().getStore().searchDocuments(" ",
getXWikiContext());
for (XWikiDocument xWikiDocument : docs) {
List<BaseObject> objects =
xWikiDocument.getXObjects(xWikiDocument.getDocumentReference());
if (objects != null) {
for (BaseObject bo : objects) {
if (bo.getName().contains("QuarXs.NodeTypeClass")) {
DefaultNodeType nt = new DefaultNodeType();
nt.setName(bo.getStringValue("name"));
nt.setGuid(bo.getGuid());
n.setType(nt);
}
}
}
}
} catch (Exception ee) {
System.out.println("Error: " + ee);
}
To test this i defined a class from a wiki-page named "NodeTypeClass" in
Space "QuarXs". But now i used /AbstractMandatoryDocumentInitializer/ to
initialize everything. The Initialization works fine and looks great, but
now my upper method is not working. I can define objects and reference to
NodeType, but can't find objects of type "NodeType" with the upper method.
Can you give me a hint?
I checked it with
{{groovy}}
import org.rogatio.quarxs.Node;
for (Node node :
services.component.getComponentManager().getInstanceList(Node.class)) {
println("* "+node.getPrettyId() )
println("** "+node.getType()) // gives back null. Reason: No
BaseObject of class "QuarXs.NodeTypeClass" found with upper method
// println("** "+node.getType().getName()) // worked fine when i made
the classes by hand
}
{{/groovy}}
If you like i post my code.
Regards,
Matthias

Hi Matthias,
You should use the Query Module (
http://extensions.xwiki.org/xwiki/bin/view/Extension/Query+Module ) to
search for documents having objects of a specified type (e.g.
QuarXs.NodeTypeClass). Also, the parameter passed to
XWikiDocument#getXObjects(DocumentReference) is the class reference,
i.e. the reference to the document that defines the class (e.g. a
reference to QuarXs.NodeTypeClass document). You can access the
javadoc from http://platform.xwiki.org/xwiki/bin/view/DevGuide/API .
Hope this helps,
Marius

Hi Marius,
thanks I found it. I used now
public String create(String className, String... values) {
String select = new String();
String from = new String();
String where = new String();
for (int i = 0; i < values.length; i++) {
String prop = "prop" + i;
String v = values[i];
select += prop + ".value";
from += "StringProperty as " + prop;
where += "and obj.id=" + prop + ".id.id and " + prop +
".id.name='" + v +
"'";
if (i + 1 < values.length) {
select += ", ";
from += ", ";
}
}
return "select " + select + " from BaseObject as obj, " + from +
" where
obj.className='" + className + "' " + where;
}
to get whatever i need.
Regards,
Matthias
