NAME
Net::XMPP::Roster - XMPP Roster Object
SYNOPSIS
Net::XMPP::Roster is a module that provides a developer an easy
interface to an XMPP roster. It provides high level functions to
query, update, and manage a user's roster.
DESCRIPTION
The Roster object seeks to provide an easy to use API for interfacing
with a user's roster. When you instantiate it, it automatically
registers with the connection to receivce the correct packets so
that it can track all roster updates, and presence packets.
Basic Functions
my $Client = new Net::XMPP::Client(...);
my $Roster = new Net::XMPP::Roster(connection=>$Client);
or
my $Roster = $Client->Roster();
$Roster->clear();
if ($Roster->exists('bob@jabber.org')) { ... }
if ($Roster->exists(Net::XMPP::JID)) { ... }
if ($Roster->groupExists("Friends")) { ... }
my @groups = $Roster->groups();
my @jids = $Roster->jids();
my @friends = $Roster->jids("group","Friends");
my @unfiled = $Roster->jids("nogroup");
if ($Roster->online('bob@jabber.org')) { ... }
if ($Roster->online(Net::XMPP::JID)) { ... }
my %hash = $Roster->query('bob@jabber.org');
my %hash = $Roster->query(Net::XMPP::JID);
my $name = $Roster->query('bob@jabber.org',"name");
my $ask = $Roster->query(Net::XMPP::JID,"ask");
my $resource = $Roster->resource('bob@jabber.org');
my $resource = $Roster->resource(Net::XMPP::JID);
my %hash = $Roster->resourceQuery('bob@jabber.org',"Home");
my %hash = $Roster->resourceQuery(Net::XMPP::JID,"Club");
my $show = $Roster->resourceQuery('bob@jabber.org',"Home","show");
my $status = $Roster->resourceQuery(Net::XMPP::JID,"Work","status");
my @resource = $Roster->resources('bob@jabber.org');
my @resource = $Roster->resources(Net::XMPP::JID);
$Roster->resourceStore('bob@jabber.org',"Home","gpgkey",key);
$Roster->resourceStore(Net::XMPP::JID,"logged on","2004/04/07 ...");
$Roster->store('bob@jabber.org',"avatar",avatar);
$Roster->store(Net::XMPP::JID,"display_name","Bob");
Advanced Functions
These functions are only needed if you want to manually control
the Roster.
$Roster->add('bob@jabber.org',
name=>"Bob",
groups=>["Friends"]
);
$Roster->add(Net::XMPP::JID);
$Roster->addResource('bob@jabber.org',
"Home",
show=>"dnd",
status=>"Working"
);
$Roster->addResource(Net::XMPP::JID,"Work");
$Roster->remove('bob@jabber.org');
$Roster->remove(Net::XMPP::JID);
$Roster->removeResource('bob@jabber.org',"Home");
$Roster->removeResource(Net::XMPP::JID,"Work");
$Roster->handler(Net::XMPP::IQ);
$Roster->handler(Net::XMPP::Presence);
METHODS
Basic Functions
new(connection=>object) - This creates and initializes the Roster
object. The connection object is required
so that the Roster can interact with the
main connection object. It needs to be an
object that inherits from
Net::XMPP::Connection.
clear() - removes everything from the database.
exists(jid) - return 1 if the JID exists in the database, undef
otherwise. The jid can either be a string, or a
Net::XMPP::JID object.
groupExists(group) - return 1 if the group exists in the database,
undef otherwise.
groups() - returns a list of all of the roster groups.
jids([type, - returns a list of all of the matching JIDs. The valid
[group]]) types are:
all - return all JIDs in the roster. (default)
nogroup - return all JIDs not in a roster group.
group - return all of the JIDs in the specified
roster group.
online(jid) - return 1 if the JID is online, undef otherwise. The
jid can either be a string, or a Net::XMPP::JID object.
query(jid, - return a hash representing all of the data in the
[key]) DB for this JID. The jid can either be a string,
or a Net::XMPP::JID object. If you specify a key,
then only the value for that key is returned.
resource(jid) - return the string representing the resource with the
highest priority for the JID. The jid can either be
a string, or a Net::XMPP::JID object.
resourceQuery(jid, - return a hash representing all of the data
resource, the DB for the resource for this JID. The
[key]) jid can either be a string, or a
Net::XMPP::JID object. If you specify a
key, then only the value for that key is
returned.
resources(jid) - returns the list of resources for the JID in order
of highest priority to lowest priority. The jid can
either be a string, or a Net::XMPP::JID object.
resourceStore(jid, - store the specified value in the DB under
resource, the specified key for the resource for this
key, JID. The jid can either be a string, or a
value) Net::XMPP::JID object.
store(jid, - store the specified value in the DB under the
key, specified key for this JID. The jid can either
value) be a string, or a Net::XMPP::JID object.
Advanced Functions
add(jid, - Manually adds the JID to the Roster with the
ask=>string, specified roster item settings. This does not
groups=>arrayref handle subscribing to other users, only
name=>string, manipulating the Roster object. The jid
subscription=>string) can either be a string or a Net::XMPP::JID.
addResource(jid, - Manually add the resource to the JID in the
resource, Roster with the specified presence settings.
priority=>int, This does not handle subscribing to other
show=>string, users, only manipulating the Roster object.
status=>string) The jid can either be a string or a
Net::XMPP::JID.
remove(jid) - Removes all reference to the JID from the Roster object.
The jid can either be a string or a Net::XMPP::JID.
removeResource(jid, - Removes the resource from the jid in the
resource) Roster object. The jid can either be a string
or a Net::XMPP::JID.
handler(packet) - Take either a Net::XMPP::IQ or Net::XMPP::Presence
packet and parse them according to the rules of the
Roster object. Note, that it will only waste CPU time
if you pass in IQs or Presences that are not roster
related.
