NAME ^

Net::XMPP3::Presence - XMPP Presence Module

SYNOPSIS ^

  Net::XMPP3::Presence is a companion to the Net::XMPP3 module.
  It provides the user a simple interface to set and retrieve all
  parts of an XMPP Presence.

DESCRIPTION ^

  A Net::XMPP3::Presence object is passed to the callback function for
  the message.  Also, the first argument to the callback functions is
  the session ID from XML::Streams.  There are some cases where you
  might want this information, like if you created a Client that
  connects to two servers at once, or for writing a mini server.

    use Net::XMPP3;

    sub presence {
      my ($sid,$Pres) = @_;
      .
      .
      .
    }

  You now have access to all of the retrieval functions available.

  To create a new presence to send to the server:

    use Net::XMPP3;

    $Pres = new Net::XMPP3::Presence();

  Now you can call the creation functions below to populate the tag
  before sending it.

METHODS ^

Retrieval functions

  GetTo()      - returns the value in the to='' attribute for the
  GetTo("jid")   <presence/>.  If you specify "jid" as an argument
                 then a Net::XMPP3::JID object is returned and
                 you can easily parse the parts of the JID.

                 $to    = $Pres->GetTo();
                 $toJID = $Pres->GetTo("jid");

  GetFrom()      - returns the value in the from='' attribute for the
  GetFrom("jid")   <presence/>.  If you specify "jid" as an argument
                   then a Net::XMPP3::JID object is returned and
                   you can easily parse the parts of the JID.

                   $from    = $Pres->GetFrom();
                   $fromJID = $Pres->GetFrom("jid");

  GetType() - returns the type='' attribute of the <presence/>.  Each
              presence is one of seven types:

                available       available to receive messages; default
                unavailable     unavailable to receive anything
                subscribe       ask the recipient to subscribe you
                subscribed      tell the sender they are subscribed
                unsubscribe     ask the recipient to unsubscribe you
                unsubscribed    tell the sender they are unsubscribed
                probe           probe

              $type = $Pres->GetType();

  GetStatus() - returns a string with the current status of the resource.

                $status = $Pres->GetStatus();

  GetPriority() - returns an integer with the priority of the resource
                  The default is 0 if there is no priority in this
                  presence.

                  $priority = $Pres->GetPriority();

  GetShow() - returns a string with the state the client should show.

              $show = $Pres->GetShow();

Creation functions

  SetPresence(to=>string|JID     - set multiple fields in the <presence/>
              from=>string|JID,    at one time.  This is a cumulative
              type=>string,        and over writing action.  If you set
              status=>string,      the "to" attribute twice, the second
              priority=>integer,   setting is what is used.  If you set
              meta=>string,        the status, and then set the priority
              icon=>string,        then both will be in the <presence/>
              show=>string,        tag.  For valid settings read the
              loc=>string)         specific Set functions below.

                        $Pres->SetPresence(TYPE=>"away",
                                           StatuS=>"Out for lunch");

  SetTo(string) - sets the to attribute.  You can either pass a string
  SetTo(JID)      or a JID object.  They must be valid JIDs or the
                  server will return an error message.
                  (ie.  bob@jabber.org/Silent Bob, etc...)

                  $Pres->SetTo("bob\@jabber.org");

  SetFrom(string) - sets the from='' attribute.  You can either pass
  SetFrom(JID)      a string or a JID object.  They must be valid JIDs
                    or the server will return an error message. (ie.
                    jabber:bob@jabber.org/Work)  This field is not
                    required if you are writing a Client since the
                    server will put the JID of your connection in there
                    to prevent spamming.

                    $Pres->SetFrom("jojo\@jabber.org");

  SetType(string) - sets the type attribute.  Valid settings are:

                    available      available to receive messages; default
                    unavailable    unavailable to receive anything
                    subscribe      ask the recipient to subscribe you
                    subscribed     tell the sender they are subscribed
                    unsubscribe    ask the recipient to unsubscribe you
                    unsubscribed   tell the sender they are unsubscribed
                    probe          probe

                    $Pres->SetType("unavailable");

  SetStatus(string) - sets the status tag to be whatever string the user
                      wants associated with that resource.

                      $Pres->SetStatus("Taking a nap");

  SetPriority(integer) - sets the priority of this resource.  The highest
                         resource attached to the xmpp account is the
                         one that receives the messages.

                         $Pres->SetPriority(10);

  SetShow(string) - sets the name of the icon or string to display for
                    this resource.

                    $Pres->SetShow("away");

  Reply(hash) - creates a new Presence object and populates the to/from
                fields.  If you specify a hash the same as with
                SetPresence then those values will override the Reply
                values.

                $Reply = $Pres->Reply();
                $Reply = $Pres->Reply(type=>"subscribed");
