Isn't doc.object(Class) part of XWiki core API?
I thought it was an alias of $doc.getObject("Class")
I want to know what APIs XWQL has access to, but I couldn't find the
information.

doc.getObjects("MyClass") is from the xwiki
core java api, but is not part
of the XWQL querying language.
The query:
select srv.port from Document doc, doc.object(Private.Network Services) as
srv order by srv.port
... translates to " select "port" field from all XObjects that are of
class "Private.Network Services", ordering by "port" field "
So this query would retrieve the value of "port" field from all of these
XObjects (that we name "srv" in the query), wherever they are and whatever
their count.

doc.getObjects was there since I had multiple
instance of the same class.

Hello,
I think this is not correct:
select srv from IN (doc.getObjects("Private.Network Services")) srv order
by srv.port
Should be more something like:
select srv.port from Document doc, doc.object(Private.Network Services)
as
srv order by srv.port
Replacing the "select srv.port" by what fields you want to retrieve.
Though obviously I'm not sure about what you wanted to achieve with your
request to start with ...

Yes, I read it, and it seems collection member
declarations don't work
in
xwiki.
