Examples of org.xmpp.packet.IQ.addExtension()

org.xmpp.packet.IQ.addExtension()

Adds the element contained in the PacketExtension to the child element of the IQ packet. IQ packets, unlike the other packet types, have a unique child element that holds the packet extensions. If an extension is added to an IQ packet that does not have a child element then an IllegalStateException will be thrown.

It is important that this is the first and last time the element contained in PacketExtension is added to another Packet. Otherwise, a runtime error will be thrown when trying to add the PacketExtension's element to the Packet's element. Future modifications to the PacketExtension will be reflected in this Packet.

Note: packet extensions on IQ packets are only for use in specialized situations. In most cases, you should only need to set the child element of the IQ. @param extension the PacketExtension whose element will be added to this Packet's element.


        if (iq.elements().isEmpty()) {
            reply.setChildElement(iq.createCopy());
            // Send the data form to the requestor


            reply.addExtension(dataForm.createCopy());
            workgroup.send(reply);
        }
    }


    public void executeSet(IQ packet, Workgroup workgroup) {

            IQ reply = IQ.createResultIQ(packet);


            if (iq.elements().isEmpty()) {
                reply.setChildElement(iq.createCopy());
                // Send the search form to the agent
                reply.addExtension(searchForm.createCopy());
                workgroupManager.send(reply);
