+class RosterItem(object):
+
+ """
+ A RosterItem is a single entry in a roster node, and tracks
+ the subscription state and user annotations of a single JID.
+
+ Roster items may use an external datastore to persist roster data
+ across sessions. Client applications will not need to use this
+ functionality, but is intended for components that do not have their
+ roster persisted automatically by the XMPP server.
+
+ Roster items provide many methods for handling incoming presence
+ stanzas that ensure that response stanzas are sent according to
+ RFC 3921.
+
+ The external datastore is accessed through a provided interface
+ object which is stored in self.db. The interface object MUST
+ provide two methods: load and save, both of which are responsible
+ for working with a single roster item. A private dictionary,
+ self._db_state, is used to store any metadata needed by the
+ interface, such as the row ID of a roster item, etc.
+
+ Interface for self.db.load:
+ load(owner_jid, jid, db_state):
+ owner_jid -- The JID that owns the roster.
+ jid -- The JID of the roster item.
+ db_state -- A dictionary containing any data saved
+ by the interface object after a save()
+ call. Will typically have the equivalent
+ of a 'row_id' value.
+
+ Interface for self.db.save:
+ save(owner_jid, jid, item_state, db_state):
+ owner_jid -- The JID that owns the roster.
+ jid -- The JID of the roster item.
+ item_state -- A dictionary containing the fields:
+ 'from', 'to', 'pending_in', 'pending_out',
+ 'whitelisted', 'subscription', 'name',
+ and 'groups'.
+ db_state -- A dictionary provided for persisting
+ datastore specific information. Typically,
+ a value equivalent to 'row_id' will be
+ stored here.
+
+ State Fields:
+ from -- Indicates if a subscription of type 'from'
+ has been authorized.
+ to -- Indicates if a subscription of type 'to' has
+ been authorized.
+ pending_in -- Indicates if a subscription request has been
+ received from this JID and it has not been
+ authorized yet.
+ pending_out -- Indicates if a subscription request has been sent
+ to this JID and it has not been accepted yet.
+ subscription -- Returns one of: 'to', 'from', 'both', or 'none'
+ based on the states of from, to, pending_in,
+ and pending_out. Assignment to this value does
+ not affect the states of the other values.
+ whitelisted -- Indicates if a subscription request from this
+ JID should be automatically accepted.
+ name -- A user supplied alias for the JID.
+ groups -- A list of group names for the JID.
+
+ Attributes:
+ xmpp -- The main SleekXMPP instance.
+ owner -- The JID that owns the roster.
+ jid -- The JID for the roster item.
+ db -- Optional datastore interface object.
+ last_status -- The last presence sent to this JID.
+ resources -- A dictionary of online resources for this JID.
+ Will contain the fields 'show', 'status',
+ and 'priority'.
+
+ Methods:
+ load -- Retrieve the roster item from an
+ external datastore, if one was provided.
+ save -- Save the roster item to an external
+ datastore, if one was provided.
+ remove -- Remove a subscription to the JID and revoke
+ its whitelisted status.
+ subscribe -- Subscribe to the JID.
+ authorize -- Accept a subscription from the JID.
+ unauthorize -- Deny a subscription from the JID.
+ unsubscribe -- Unsubscribe from the JID.
+ send_presence -- Send a directed presence to the JID.
+ send_last_presence -- Resend the last sent presence.
+ handle_available -- Update the JID's resource information.
+ handle_unavailable -- Update the JID's resource information.
+ handle_subscribe -- Handle a subscription request.
+ handle_subscribed -- Handle a notice that a subscription request
+ was authorized by the JID.

+ removed by the JID.
