process
public void process(Packet packet, XMPPResourceConnection session, NonAuthUserRepository repo, java.util.Queue<Packet> results, java.util.Map<java.lang.String,java.lang.Object> settings) throws XMPPException
Performs processing of presence packets and calls different methods for particularRosterAbstract.PresenceType
- Specified by:
process
in interfaceXMPPProcessorIfc
- Parameters:
packet
- packet is which being processed. This parameter may never be null. Even though this is not immutable object it mustn't be altered. None of it's fields or attributes can be changed during processing.session
- user session which keeps all the user session data and also gives an access to the user's repository data. It allows for storing information in a permanent storage or in memory only during the live of the online session. This parameter can be null if there is no online user session at the time of the packet processing.repo
- this is a user data storage which is normally used when the user session (parameter above) is null. This is repository allows for a very restricted access only. It allows for storing some user private data (doesn't allow overwriting existing data) like messages for offline users and it also allows for reading user public data like VCard.results
