# NAME

Net::XMPP::Presence - XMPP Presence Module

# SYNOPSIS

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.

# DESCRIPTION

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.

# 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 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();

## 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);

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();

RemoveFrom

  removes the from attribute from the <presence/>.

      $Pres->RemoveFrom();

RemoveType

  removes the type attribute from the <presence/>.

      $Pres->RemoveType();

RemoveStatus

  removes the <status/> element from the <presence/>.

      $Pres->RemoveStatus();

RemovePriority

  removes the <priority/> element from the <presence/>.

      $Pres->RemovePriority();

RemoveShow

  removes the <show/> element from the <presence/>.

      $Pres->RemoveShow();

## Test functions

DefinedTo

  returns 1 if the to attribute is defined in the <presence/>, 0 otherwise.

      $test = $Pres->DefinedTo();

DefinedFrom

  returns 1 if the from attribute is defined in the <presence/>, 0 otherwise.

      $test = $Pres->DefinedFrom();

DefinedType

  returns 1 if the type attribute is defined in the <presence/>, 0 otherwise.

      $test = $Pres->DefinedType();

DefinedStatus

  returns 1 if <status/> is defined in the <presence/>, 0 otherwise.
