NAME
Net::Jabber::Presence - Jabber Presence Module
SYNOPSIS
Net::Jabber::Presence is a companion to the Net::Jabber module.
It provides the user a simple interface to set and retrieve all
parts of a Jabber Presence.
DESCRIPTION
To initialize the Presence with a Jabber <presence/> you must pass it
the XML::Stream has. For example:
my $presence = new Net::Jabber::Presence(%hash);
There has been a change from the old way of handling the callbacks.
You no longer have to do the above yourself, a Net::Jabber::Presence
object is passed to the callback function for the message. Also,
the first argument to the callback functions is the session ID from
XML::Streams. There are some cases where you might want this
information, like if you created a Client that connects to two servers
at once, or for writing a mini server.
use Net::Jabber qw(Client);
sub presence {
my ($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::Jabber qw(Client);
$Pres = new Net::Jabber::Presence();
Now you can call the creation functions below to populate the tag
before sending it.
For more information about the array format being passed to the
CallBack please read the Net::Jabber::Client documentation.
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::Jabber::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::Jabber::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 Jabber
Identifiers or the server will return an error message.
(ie. jabber: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 Jabber
Identifiers 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 jabber 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");
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.
$test = $Pres->DefinedStatus();
DefinedPriority() - returns 1 if <priority/> is defined in the
<presence/>, 0 otherwise.
$test = $Pres->DefinedPriority();
DefinedShow() - returns 1 if <show/> is defined in the <presence/>,
0 otherwise.
$test = $Pres->DefinedShow();
