NAME
Net::XMPP3::Presence - XMPP Presence Module
SYNOPSIS
Net::XMPP3::Presence is a companion to the Net::XMPP3 module.
It provides the user a simple interface to set and retrieve all
parts of an XMPP Presence.DESCRIPTION
A Net::XMPP3::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::XMPP3;
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::XMPP3;
$Pres = new Net::XMPP3::Presence();
Now you can call the creation functions below to populate the tag
before sending it.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::XMPP3::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::XMPP3::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 JIDs or the
server will return an error message.
(ie. 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 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(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 xmpp 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");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.
$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();AUTHOR
