Net::Jabber::XDB - Jabber XDB Library
Net::Jabber::XDB is a companion to the Net::Jabber module. It provides the user a simple interface to set and retrieve all parts of a Jabber XDB.
Net::Jabber::XDB differs from the other Net::Jabber::* modules in that the XMLNS of the data is split out into more submodules under XDB. For specifics on each module please view the documentation for each Net::Jabber::Data::* module. To see the list of avilable namspaces and modules see Net::Jabber::Data.
To initialize the XDB with a Jabber <xdb/> you must pass it the XML::Parser Tree array. For example:
my $xdb = new Net::Jabber::XDB(@tree);
There has been a change from the old way of handling the callbacks. You no longer have to do the above, a Net::Jabber::XDB object is passed to the callback function for the xdb:
use Net::Jabber qw(Component);
sub xdb { my ($XDB) = @_; . . . }
You now have access to all of the retrieval functions available.
To create a new xdb to send to the server:
use Net::Jabber;
$XDB = new Net::Jabber::XDB(); $XDBType = $XDB->NewData( type ); $XDBType->SetXXXXX("yyyyy");
Now you can call the creation functions for the XDB, and for the <data/> on the new Data object itself. See below for the <xdb/> 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.
GetTo() - returns either a string with the Jabber Identifier, GetTo("jid") or a Net::Jabber::JID object for the person who is going to receive the <xdb/>. To get the JID object set the string to "jid", otherwise leave blank for the text string.
$to = $XDB->GetTo(); $toJID = $XDB->GetTo("jid");
GetFrom() - returns either a string with the Jabber Identifier, GetFrom("jid") or a Net::Jabber::JID object for the person who sent the <xdb/>. To get the JID object set the string to "jid", otherwise leave blank for the text string.
$from = $XDB->GetFrom(); $fromJID = $XDB->GetFrom("jid");
GetType() - returns a string with the type <xdb/> this is.
$type = $XDB->GetType();
GetID() - returns an integer with the id of the <xdb/>.
$id = $XDB->GetID();
GetAction() - returns a string with the action <xdb/> this is.
$action = $XDB->GetAction();
GetMatch() - returns a string with the match <xdb/> this is.
$match = $XDB->GetMatch();
GetError() - returns a string with the text description of the error.
$error = $XDB->GetError();
GetErrorCode() - returns a string with the code of error.
$errorCode = $XDB->GetErrorCode();
GetData() - returns a Net::Jabber::Data object that contains the data in the <data/> of the <xdb/>.
$dataTag = $XDB->GetData();
GetDataXMLNS() - returns a string with the namespace of the data for this <xdb/>, if one exists.
$xmlns = $XDB->GetDataXMLNS();
SetXDB(to=>string|JID, - set multiple fields in the <xdb/> at one from=>string|JID, time. This is a cumulative and over id=>string, writing action. If you set the "to" type=>string, attribute twice, the second setting is action=>string, what is used. If you set the status, and match=>string) then set the priority then both will be in errorcode=>string, the <xdb/> tag. For valid settings read the error=>string) specific Set functions below.
$XDB->SetXDB(type=>"get", to=>"bob\@jabber.org", data=>"info");
$XDB->SetXDB(to=>"bob\@jabber.org", errorcode=>403, error=>"Permission Denied");
SetTo(string) - sets the to attribute. You can either pass a string SetTo(JID) or a JID object. They must be a valid Jabber Identifiers or the server will return an error message. (ie. jabber:bob@jabber.org, etc...)
$XDB->SetTo("bob\@jabber.org");
SetFrom(string) - sets the from attribute. You can either pass a string SetFrom(JID) or a JID object. They must be a valid Jabber Identifiers or the server will return an error message. (ie. jabber:bob@jabber.org, etc...)
$XDB->SetFrom("me\@jabber.org");
SetType(string) - sets the type attribute. Valid settings are:
get request information set set information result results of a get error there was an error
$XDB->SetType("set");
SetAction(string) - sets the error code of the <xdb/>.
$XDB->SetAction("foo");
SetMatch(string) - sets the error code of the <xdb/>.
$XDB->SetMatch("foo");
SetErrorCode(string) - sets the error code of the <xdb/>.
$XDB->SetErrorCode(403);
SetError(string) - sets the error string of the <xdb/>.
$XDB->SetError("Permission Denied");
NewData(string) - creates a new Net::Jabber::Data object with the namespace in the string. In order for this function to work with a custom namespace, you must define and register that namespace with the XDB module. For more information please read the documentation for Net::Jabber::Data.
$dataObj = $XDB->NewData("jabber:xdb:auth"); $dataObj = $XDB->NewData("jabber:xdb:roster");
Reply(hash) - creates a new XDB object and populates the to/from fields. If you specify a hash the same as with SetXDB then those values will override the Reply values.
$xdbReply = $XDB->Reply(); $xdbReply = $XDB->Reply(type=>"result");
DefinedTo() - returns 1 if the to attribute is defined in the <xdb/>, 0 otherwise.
$test = $XDB->DefinedTo();
DefinedFrom() - returns 1 if the from attribute is defined in the <xdb/>, 0 otherwise.
$test = $XDB->DefinedFrom();
DefinedID() - returns 1 if the id attribute is defined in the <xdb/>, 0 otherwise.
$test = $XDB->DefinedID();
DefinedType() - returns 1 if the type attribute is defined in the <xdb/>, 0 otherwise.
$test = $XDB->DefinedType();
DefinedAction() - returns 1 if the action attribute is defined in the <xdb/>, 0 otherwise.
$test = $XDB->DefinedAction();
DefinedMatch() - returns 1 if the match attribute is defined in the <xdb/>, 0 otherwise.
$test = $XDB->DefinedMatch();
DefinedError() - returns 1 if <error/> is defined in the <xdb/>, 0 otherwise.
$test = $XDB->DefinedError();
DefinedErrorCode() - returns 1 if the code attribute is defined in <error/>, 0 otherwise.
$test = $XDB->DefinedErrorCode();
