Examples of org.xmpp.packet.Presence

org.xmpp.packet.Presence
Presence packet. Presence packets are used to express an entity's current network availability and to notify other entities of that availability. Presence packets are also used to negotiate and manage subscriptions to the presence of other entities.
A presence optionally has a {@link Type}. @author Matt Tucker
