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

$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
