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.
