|

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.
|

handle_unsubscribe -- Handle an unsubscribe request.
|

handle_unsubscribed -- Handle a notice that a subscription was
|

removed by the JID.
