perl v5.34.0                                       2022-06-16                           Net::XMPP::Presence(3pm)

       A Net::XMPP::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::XMPP;

           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::XMPP;

           $Pres = Net::XMPP::Presence->new();

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

Retrievalfunctions
       GetTo
             GetTo()

           returns the value in the to='' attribute for the <presence/>.

             GetTo("jid")

           If you specify "jid" as an argument then a Net::XMPP::JID object is returned and you can easily parse
           the parts of the JID.

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

       GetFrom
             GetFrom()

           returns the value in the from='' attribute for the <presence/>.

             GetFrom("jid")

           If you specify "jid" as an argument then a Net::XMPP::JID object is returned and you can easily parse
           the parts of the JID.

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

       GetType
             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
             GetStatus()

           returns a string with the current status of the resource.

             $status = $Pres->GetStatus();

       GetPriority
             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
             GetShow()

           Returns a string with the state the client should show.

             $show = $Pres->GetShow();

   Creationfunctions
       SetPresence
             SetPresence(to=>string|JID
                         from=>string|JID,
                         type=>string,
                         status=>string,
                         priority=>integer,
                         meta=>string,
                         icon=>string,
                         show=>string,
                         loc=>string)

           set  multiple  fields  in the <presence/> at one time.  This is a cumulative and over writing action.
           If you set the "to" attribute twice, the second setting is what is used.  If you set the status,  and
           then set the priority then both will be in the <presence/> tag.  For valid settings read the specific
           Set functions below.

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

       SetTo
             SetTo(string)
             SetTo(JID)

           sets the to attribute.  You can either pass a string 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
             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
             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
             SetStatus(string)

           sets the status tag to be whatever string the user wants associated with that resource.

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

       SetPriority
             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
             SetShow(string)

           Sets the name of the icon or string to display for this resource.

             $Pres->SetShow("away");

       Reply
             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");

       Net::XMPP::Presence - XMPP Presence Module

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