tigase.server.sreceiver
Class StanzaReceiver

java.lang.Object
  tigase.server.BasicComponent
      tigase.server.AbstractMessageReceiver
          tigase.server.sreceiver.StanzaReceiver

All Implemented Interfaces:

Configurable, XMPPService, MessageReceiver, ServerComponent, StanzaReceiverIfc, StatisticsContainer, VHostListener

public class StanzaReceiver
extends AbstractMessageReceiver
implements Configurable, XMPPService, StanzaReceiverIfc

This is a sibling to StanzaSender class and offers just an opposite functionality. It can receive XMPP packets to do something with them. And what to do it depends on the destination address. Destination address points to certain receiver task and this is up to task to decide what to do with the stanza. Task address is just a usual Jabber ID: task-short-name@srec.tigase.org.

Like public chat rooms in MUC tasks can be preconfigured in the StanzaReceiver configuration or can be created on demand using ad-hoc commands and service-discovery. User can subscribe to some tasks and can add them to the roster just like a normal contacts. This allows to use the functionality from all existing clients without implementing any special protocols or extensions.

Possible tasks are:

• Interests groups - simple stanza (message) distribution to a group of interested ppl. To receive this information user has to subscribe to the task first. It is a bit like a MUC without a chat room or like a mailing list.
• Persistent storage - which is like an archive of some information for group of ppl.
• Web page publishing - this might be useful for web sites with kind of Short, instant news board where selected users can send information and they are published instantly. (Through the database for example.)
• Forums integration - this might be useful for kind of forums where you can post messages from Web site as well as from your Jabber client.

Task creation parameters:

• Task short name - the nick name of the task which is used to create Jabber ID for the task.
• Task description - description of the task what is the purpose of the task.
• Task type - the server, through ad-hoc commands should present available tasks types which can be created. User can select a task to create. There may be some restrictions on tasks creation like certain types can be created only by server administrator or some tasks types can be created only once on single server and so on.
• Subscription list - server admin should be able to add list of users who might be interested in subscription to the task. After task is created subscribe presence is sent to these users and they can accept the subscription or not.
• Subscription restrictions - who may subscribe to the task like: public task - anybody can subscribe, local users only - users from the local server (domain) only can subscribe, by regex - regular expression matching JIDs, moderated subscription - anybody may request subscription but the creator of the task must approve the subscription.
• On line only - the task may distribute packets to online users only.
• Replace sender address - whether sender address should be replaced with task address. This might be useful depending where the responses should go. If the list is kind on announces board like new version release then maybe replies should go to the sender. If this is more like topic discussion group then the reply should go to all subscribers.
• Message type - whether messages should be distributed as a chat, headline or normal.
• Who can post - who can send a message for processing, possible options are: all, subscribed, owner, list

There can be also some per task specific settings...
