Net::Jabber::X(3pm)

Net::Jabber::X - Jabber X Module

  Net::Jabber::X is a companion to the Net::Jabber module. It
  provides the user a simple interface to set and retrieve all
  parts of a Jabber X.


  Net::Jabber::X differs from the other modules in that its behavior
  and available functions are based off of the XML namespace that is
  set in it.  The current list of supported namespaces is:


    jabber:x:autoupdate
    jabber:x:conference
    jabber:x:delay
    jabber:x:encrypted
    jabber:x:event
    jabber:x:expire
    jabber:x:form
    jabber:x:oob
    jabber:x:roster
    jabber:x:signed
    jabber:x:sxpm


  For more information on what these namespaces are for, visit
  http://www.jabber.org and browse the Jabber Programmers Guide.


  Each of these namespaces provide Net::Jabber::X with the functions
  to access the data.  By using the AUTOLOAD function the functions for
  each namespace is used when that namespace is active.


  To access a X object you must create an object and use the
  access functions there to get to the X.  To initialize the object with
  a Jabber packet you must pass it the XML::Stream hash from the
  Net::Jabber::Client module.


    my $mess = new Net::Jabber::Message(%hash);


  There has been a change from the old way of handling the callbacks.
  You no longer have to do the above yourself, a Net::Jabber
  object is passed to the callback function for the message.  Also,
  the first argument to the callback functions is the session ID from
  XML::Streams.  There are some cases where you might want this
  information, like if you created a Client that connects to two servers
  at once, or for writing a mini server.


    use Net::Jabber qw(Client);


    sub messageCB {
      my ($Mess) = @_;
      my $x = $Mess->GetX("jabber:x:delay");
      .
      .
      .
    }


  You now have access to all of the retrieval functions available.


  To create a new x to send to the server:


    use Net::Jabber qw(Client);


    my $message = new Net::Jabber::Message();
    my $x = $message->NewX("jabber:x:oob");


  Now you can call the creation functions for the X as defined in the
  proper namespace.  See below for the general <x/> functions broken down
  by namespace.


  For more information about the array format being passed to the CallBack
  please read the Net::Jabber::Client documentation.

Generic Retrieval functions

  GetXMLNS() - returns a string with the namespace of the packet that
               the <x/> contains.


               $xmlns = $X->GetXMLNS();


  GetX(string) - since the behavior of this module depends on the
                 namespace, an X object may contain X objects. This
                 helps to leverage code reuse by making children
                 behave in the same manner.  More than likely this
                 function will never be called.


                 @x = GetX();
                 @x = GetX("jabber:x:delay");

Generic Creation functions

  SetXMLNS(string) - sets the xmlns of the <x/> to the string.


                     $X->SetXMLNS("jabber:x:delay");

In an effort to make maintaining this document easier, I am not going to go into full detail on each of these functions. Rather I will present the functions in a list with a type in the first column to show what they return, or take as arugments. Here is the list of types I will use:

  string  - just a string
  array   - array of strings
  flag    - this means that the specified child exists in the
            XML <child/> and acts like a flag.  get will return
            0 or 1.
  JID     - either a string or Net::Jabber::JID object.
  objects - creates new objects, or returns an array of
            objects.
  special - this is a special case kind of function.  Usually
            just by calling Set() with no arguments it will
            default the value to a special value, like OS or time.
            Sometimes it will modify the value you set, like
            in jabber:iq:version SetVersion() the function
            adds on the Net::Jabber version to the string
            just for advertisement purposes. =)
  master  - this desribes a function that behaves like the
            SetMessage() function in Net::Jabber::Message.
            It takes a hash and sets all of the values defined,
            and the Set returns a hash with the values that
            are defined in the object.

  Part of the flexability of this module is that you can define your own
  namespace.  For more information on this topic, please read the
  Net::Jabber::Namespaces man page.
