Net::Jabber::Query - Jabber Query Library
Net::Jabber::Query is a companion to the Net::Jabber::IQ module. It provides the user a simple interface to set and retrieve all parts of a Jabber IQ Query.
Net::Jabber::Query differs from the other modules in that its behavior and available functions are based off of the XML namespace that is set in it. The current list of supported namespaces is:
jabber:iq:agent
jabber:iq:agents
jabber:iq:auth
jabber:iq:autoupdate
jabber:iq:browse
jabber:iq:conference
jabber:iq:filter
jabber:iq:gateway
jabber:iq:last
jabber:iq:oob
jabber:iq:pass
jabber:iq:register
jabber:iq:roster
jabber:iq:search
jabber:iq:time
jabber:iq:version
For more information on what these namespaces are for, visit http://www.jabber.org and browse the Jabber Programmers Guide.
Each of these namespaces provide Net::Jabber::Query with the functions to access the data. By using the AUTOLOAD function the functions for each namespace is used when that namespace is active.
To access a Query object you must create an IQ object and use the access functions there to get to the Query. To initialize the IQ with a Jabber <iq/> you must pass it the XML::Stream hash from the Net::Jabber::Client module.
my $iq = new Net::Jabber::IQ(%hash);
There has been a change from the old way of handling the callbacks. You no longer have to do the above yourself, a Net::Jabber::IQ object is passed to the callback function for the message. Also, the first argument to the callback functions is the session ID from XML::Streams. There are some cases where you might want this information, like if you created a Client that connects to two servers at once, or for writing a mini server.
use Net::Jabber qw(Client);
sub iqCB {
my ($IQ) = @_;
my $query = $IQ->GetQuery();
.
.
.
}
You now have access to all of the retrieval functions available for that namespace.
To create a new iq to send to the server:
use Net::Jabber;
my $iq = new Net::Jabber::IQ();
$query = $iq->NewQuery("jabber:iq:register");
Now you can call the creation functions for the Query as defined in the proper namespaces. See below for the general <query/> functions, and in each query module for those functions.
For more information about the array format being passed to the CallBack please read the Net::Jabber::Client documentation.
GetXMLNS() - returns a string with the namespace of the query that
the <iq/> contains.
$xmlns = $IQ->GetXMLNS();
GetQuery() - since the behavior of this module depends on the
namespace, a Query object may contain Query objects.
This helps to leverage code reuse by making children
behave in the same manner. More than likely this
function will never be called.
@query = GetQuery()
SetXMLNS(string) - sets the xmlns of the <query/> to the string.
$query->SetXMLNS("jabber:iq:roster");
In an effort to make maintaining this document easier, I am not going to go into full detail on each of these functions. Rather I will present the functions in a list with a type in the first column to show what they return, or take as arugments. Here is the list of types I will use:
string - just a string
array - array of strings
flag - this means that the specified child exists in the
XML <child/> and acts like a flag. get will return
0 or 1.
JID - either a string or Net::Jabber::JID object.
objects - creates new objects, or returns an array of
objects.
special - this is a special case kind of function. Usually
just by calling Set() with no arguments it will
default the value to a special value, like OS or time.
Sometimes it will modify the value you set, like
in jabber:iq:version SetVersion() the function
adds on the Net::Jabber version to the string
just for advertisement purposes. =)
master - this desribes a function that behaves like the
SetMessage() function in Net::Jabber::Message.
It takes a hash and sets all of the values defined,
and the Set returns a hash with the values that
are defined in the object.

Part of the flexability of this module is that you can define your own namespace. For more information on this topic, please read the Net::Jabber::Namespaces man page.
