## NAME
    [Net::XMPP::Presence](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP%3A%3APresence/markdown) - XMPP Presence Module

## SYNOPSIS
    [Net::XMPP::Presence](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP%3A%3APresence/markdown) is a companion to the [Net::XMPP](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP/markdown) module. It provides the user a simple
    interface to set and retrieve all parts of an XMPP Presence.

## DESCRIPTION
    A [Net::XMPP::Presence](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP%3A%3APresence/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3AStreams/markdown). 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](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP/markdown);

        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](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP/markdown);

        $Pres = [Net::XMPP::Presence](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP%3A%3APresence/markdown)->new();

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

## METHODS
### Retrieval functions
    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](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP%3A%3AJID/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/Net%3A%3AXMPP%3A%3AJID/markdown) 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();

### Creation functions
    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)](https://www.chedong.com/phpMan.php/man/SetPriority/10/markdown);

    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");

### Removal functions
    RemoveTo
        removes the to attribute from the <presence/>.

          $Pres->RemoveTo();
