Net::XMPP::JID(3)					User Contributed Perl Documentation					 Net::XMPP::JID(3)

NAME
Net::XMPP::JID - XMPP JID Module SYNOPSIS
Net::XMPP::JID is a companion to the Net::XMPP module. It provides the user a simple interface to set and retrieve all parts of a Jabber ID (userid on a server). DESCRIPTION
To initialize the JID you must pass it the string that represents the jid from the XML packet. Inside the XMPP modules this is done automatically and the JID object is returned instead of a string. For example, in the callback function for the XMPP object foo: use Net::XMPP; sub foo { my $foo = new Net::XMPP::Foo(@_); my $from = $foo->GetFrom(); my $JID = new Net::XMPP::JID($from); . . . } You now have access to all of the retrieval functions available. To create a new JID to send to the server: use Net::XMPP; $JID = new Net::XMPP::JID(); Now you can call the creation functions below to populate the tag before sending it. Retrieval functions $userid = $JID->GetUserID(); $server = $JID->GetServer(); $resource = $JID->GetResource(); $JID = $JID->GetJID(); $fullJID = $JID->GetJID("full"); $baseJID = $JID->GetJID("base"); Creation functions $JID->SetJID(userid=>"bob", server=>"jabber.org", resource=>"Work"); $JID->SetJID('blue@moon.org/Home'); $JID->SetUserID("foo"); $JID->SetServer("bar.net"); $JID->SetResource("Foo Bar"); METHODS
Retrieval functions GetUserID() - returns a string with the userid of the JID. If the string is an address (bob%jabber.org) then the function will return it as an address (bob@jabber.org). GetServer() - returns a string with the server of the JID. GetResource() - returns a string with the resource of the JID. GetJID() - returns a string that represents the JID stored GetJID("full") within. If the "full" string is specified, then GetJID("base") you get the full JID, including Resource, which should be used to send to the server. If the "base", string is specified, then you will just get user@server, or the base JID. Creation functions SetJID(userid=>string, - set multiple fields in the jid at server=>string, one time. This is a cumulative resource=>string) and over writing action. If you set SetJID(string) the "userid" attribute twice, the second setting is what is used. If you set the server, and then set the resource then both will be in the jid. If all you pass is a string, then that string is used as the JID. For valid settings read the specific Set functions below. SetUserID(string) - sets the userid. Must be a valid userid or the server will complain if you try to use this JID to talk to the server. If the string is an address then it will be converted to the % form suitable for using as a User ID. SetServer(string) - sets the server. Must be a valid host on the network or the server will not be able to talk to it. SetResource(string) - sets the resource of the userid to talk to. AUTHOR
