NAME ^

Net::Jabber::XDB - Jabber XDB Library

SYNOPSIS ^

  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.

DESCRIPTION ^

  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.

METHODS ^

Retrieval functions

  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();

Creation functions

  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");

                0 otherwise.

                $test = $XDB->DefinedTo();

  DefinedFrom() - returns 1 if the from attribute is defined in the <xdb/>,

                   $test = $XDB->DefinedError();

  DefinedErrorCode() - returns 1 if the code attribute is defined in
                       <error/>, 0 otherwise.
