NAME
Net::Jabber::Data - Jabber Data LibrarySYNOPSIS
Net::Jabber::Data is a companion to the Net::Jabber::XDB module. It provides the user a simple interface to set and retrieve all parts of a Jabber XDB Data.
DESCRIPTION
Net::Jabber::Data 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:auth jabber:iq:auth:0k jabber:iq:register jabber:iq:roster 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::Data 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 Data object you must create an XDB object and use the access functions there to get to the Data. To initialize the XDB with a Jabber <xdb/> you must pass it the XML::Stream hash from the Net::Jabber::Client module. my $xdb = new Net::Jabber::XDB(%hash); There has been a change from the old way of handling the callbacks. You no longer have to do the above yourself, a Net::Jabber::XDB object is passed to the callback function for the message. Also, the first argument to the callback functions is the session ID from XML::Streams. There are some cases where you might want this information, like if you created a Client that connects to two servers at once, or for writing a mini server. use Net::Jabber qw(Client); sub xdbCB { my ($sid,$XDB) = @_; my $data = $XDB->GetData(); . . . } You now have access to all of the retrieval functions available for that namespace. To create a new xdb to send to the server: use Net::Jabber; my $xdb = new Net::Jabber::XDB(); $data = $xdb->NewData("jabber:iq:auth"); Now you can call the creation functions for the Data as defined in the proper namespaces. See below for the general <data/> functions, and in each data module for those functions. For more information about the array format being passed to the CallBack please read the Net::Jabber::Client documentation.
METHODS
Retrieval functions
GetXMLNS() - returns a string with the namespace of the data that the <xdb/> contains. $xmlns = $XDB->GetXMLNS(); GetData() - since the behavior of this module depends on the namespace, a Data object may contain Data objects. This helps to leverage code reuse by making children behave in the same manner. More than likely this function will never be called. @data = GetData()
Creation functions
SetXMLNS(string) - sets the xmlns of the <data/> to the string. $data->SetXMLNS("jabber:xdb: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:xdb: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.

CUSTOM NAMESPACES
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.
