Examples of org.xmpp.packet.Packet

org.xmpp.packet.Packet
An XMPP packet (also referred to as a stanza). Each packet is backed by a DOM4J Element. A set of convenience methods allows easy manipulation of the Element, or the Element can be accessed directly and manipulated.
There are three core packet types:
- {@link Message} -- used to send data between users.
- {@link Presence} -- contains user presence information or is usedto manage presence subscriptions.
- {@link IQ} -- exchange information and perform queries using arequest/response protocol.
