Class XDB

All Implemented Interfaces:
Extension, Packet,

public class XDB
extends ContentPacket

A XDBPacket object represents a single XDB packet, which is used to set and query information between the server components and any data store.

<xdb type="get|set|result|error" to="user@service/namespage">
  <query xmlns="namespace">
    information custom to the namespace..

Note that unlike other basic packet types, XDB does not do any error responses. If there is a problem, the jabber server will retry events until the client component times out. To report errors, use <log> packets.

Constructor Detail


public XDB(XDBBuilder builder)
    throws java.lang.InstantiationException
Creates a new InfoQuery instance. Note that because of the complexity of the InfoQuery object and because the object is immutable after creation, a builder object is needed in order to construct this object.

builder - an InfoQueryBuilder holding appropriate values
java.lang.InstantiationException - if the values supplied by the InfoQueryBuilder are not sufficient to create a 'correctly-formed' InfoQuery packet.
