Method Detail

getBuddies

public JID[] getBuddies(XMPPResourceConnection session)
                 throws NotAuthorizedException

Description copied from interface: DynamicRosterIfc

getBuddies method returns String array with all roster buddies JIDs. Normally they are bare JIDs (without resource part). This method is normally used by presence plugin to send probe and initial presence to all contacts in the dynamic roster.

Specified by:

getBuddies in interface DynamicRosterIfc

Parameters:

session - a XMPPResourceConnection value of the connection session object.

Returns:

a String[] array of bare JIDs for the dynamic part of the user roster.

Throws:

NotAuthorizedException - may be thrown if the connection session is not yet authenticated but authorization is required to access roster data.

getBuddyItem

public Element getBuddyItem(XMPPResourceConnection session,
                            JID buddy)
                     throws NotAuthorizedException

Description copied from interface: DynamicRosterIfc

getBuddyItem method returns buddy item element for a given JID or null if the buddy doesn't exist on the user roster list.

Specified by:

getBuddyItem in interface DynamicRosterIfc

Parameters:

session - a XMPPResourceConnection value of the connection session object.

buddy - a String value of the buddy JID. It may be bare JID or full JID.

Returns:

an Element value of the XML element with all the roster item data - JID, subscription, nick name and groups. Sample code for creating the buddy element could look like this:

Element item = new Element("item", new Element[] {
     new Element("group", "Tigase devs")},
  new String[] {"jid", "subscription", "name"},
  new String[] {peer, "both", JIDUtils.getNodeNick(peer)});

Throws:

NotAuthorizedException - may be thrown if the connection session is not yet authenticated but authorization is required to access roster data.

getItemExtraData

public Element getItemExtraData(Element item)

Description copied from interface: DynamicRosterIfc

Returns a new roster Item element with additional, non-standard information for a given item. This is a way to associate custom roster information with a contact.

Specified by:

getItemExtraData in interface DynamicRosterIfc

Parameters:

item - is a Element

Returns:

a value of Element

getRosterItems

public List<Element> getRosterItems(XMPPResourceConnection session)
                             throws NotAuthorizedException

Description copied from interface: DynamicRosterIfc

getRosterItems method returns a full list with all buddies generated by this dynamic roster implementation. The list contains all contacts for the roster with all contacts details - buddy JID, nick name, subscription (typically always both) and groups. Please have a look at getBuddyItem(...) description for details how to create an Element entry for the roster item.
In theory you could here call the getBuddies(...) method and then for each entry from the array call the getBuddyItem(...). I strongly advice to not do it. This is a server with thousands of connected users and possibly thousands of packets going through the server. Think of a performance and execute database query once if possible rather then many times.

Specified by:

getRosterItems in interface DynamicRosterIfc

Parameters:

session - a XMPPResourceConnection value of the connection session object.

Returns:

a List<Element> value

Throws:

NotAuthorizedException - may be thrown if the connection session is not yet authenticated but authorization is required to access roster data.

Description copied from interface: DynamicRosterIfc
