Constructor & Destructor Documentation
Member Function Documentation
| virtual void handleItemAdded |
( |
const JID & |
jid | ) |
|
|
pure virtual |
Reimplement this function if you want to be notified about new items on the server-side roster (items subject to a so-called Roster Push). This function will be called regardless who added the item, either this resource or another. However, it will not be called for JIDs for which presence is received without them being on the roster.
- Parameters
-
| jid | The new item's full address. |
| virtual void handleItemRemoved |
( |
const JID & |
jid | ) |
|
|
pure virtual |
Reimplement this function if you want to be notified about items that were removed from the server-side roster (items subject to a so-called Roster Push). This function will be called regardless who deleted the item, either this resource or another.
- Parameters
-
| jid | The removed item's full address. |
| virtual void handleItemSubscribed |
( |
const JID & |
jid | ) |
|
|
pure virtual |
Reimplement this function if you want to be notified about items which authorised subscription.
- Parameters
-
| jid | The authorising item's full address. |
| virtual void handleItemUnsubscribed |
( |
const JID & |
jid | ) |
|
|
pure virtual |
Reimplement this function if you want to be notified about items which removed subscription authorization.
- Parameters
-
| jid | The item's full address. |
| virtual void handleItemUpdated |
( |
const JID & |
jid | ) |
|
|
pure virtual |
Reimplement this function if you want to be notified about items that were modified on the server-side roster (items subject to a so-called Roster Push). A roster push is initiated if a second resource of this JID modifies an item stored on the server-side contact list. This can include modifying the item's name, its groups, or the subscription status. These changes are pushed by the server to all connected resources. This is why this function will be called if you modify a roster item locally and synchronize it with the server.
- Parameters
-
| jid | The modified item's full address. |
| virtual void handleNonrosterPresence |
( |
const Presence & |
presence | ) |
|
|
pure virtual |
This function is called whenever presence from an entity is received which is not in the roster.
- Parameters
-
| presence | The full presence stanza. |
| virtual void handleRoster |
( |
const Roster & |
roster | ) |
|
|
pure virtual |
Reimplement this function if you want to receive the whole server-side roster on the initial roster push. After successful authentication, RosterManager asks the server for the full server-side roster. Invocation of this method announces its arrival. Roster item status is set to 'unavailable' until incoming presence info updates it. A full roster push only happens once per connection.
- Parameters
-
| virtual void handleRosterError |
( |
const IQ & |
iq | ) |
|
|
pure virtual |
This function is called if the server returned an error.
- Parameters
-
This function is called on every status change of an item in the roster. If the presence is of type Unavailable, then the resource has already been removed from the RosterItem.
- Parameters
-
| item | The roster item. |
| resource | The resource that changed presence. |
| presence | The item's new presence. |
| msg | The status change message. |
- Since
- 0.9
This function is called on every status change of a JID that matches the Client's own JID. If the presence is of type Unavailable, then the resource has already been removed from the RosterItem.
- Parameters
-
| item | The self item. |
| resource | The resource that changed presence. |
| presence | The item's new presence. |
| msg | The status change message. |

| virtual bool handleSubscriptionRequest |
( |
const JID & |
jid, |
|
|
const std::string & |
msg |
|
) |
| |
|
pure virtual |
This function is called when an entity wishes to subscribe to this entity's presence. If the handler is registered as a asynchronous handler for subscription requests, the return value of this function is ignored. In this case you should use RosterManager::ackSubscriptionRequest() to answer the request.
- Parameters
-
| jid | The requesting item's address. |
| msg | A message sent along with the request. |
- Returns
- Return true to allow subscription and subscribe to the remote entity's presence, false to ignore the request.
| virtual bool handleUnsubscriptionRequest |
( |
const JID & |
jid, |
|
|
const std::string & |
msg |
|
) |
| |
|
pure virtual |
This function is called when an entity unsubscribes from this entity's presence. If the handler is registered as a asynchronous handler for subscription requests, the return value of this function is ignored. In this case you should use RosterManager::unsubscribe() if you want to unsubscribe yourself from the contct's presence and to remove the contact from the roster.
- Parameters
-
| jid | The item's address. |
| msg | A message sent along with the request. |
- Returns
- Return true to unsubscribe from the remote entity, false to ignore.
