package Net::Jabber::XDB;

=head1 NAME

Net::Jabber::XDB - Jabber XDB Library

=head1 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.

=head1 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  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
  on the new Data object itself.  See below for the  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.

=head1 METHODS

=head2 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 .  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 .  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  this is.

              $type = $XDB->GetType();

  GetID() - returns an integer with the id of the .

            $id = $XDB->GetID();

  GetAction() - returns a string with the action  this is.

              $action = $XDB->GetAction();

  GetMatch() - returns a string with the match  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  of the .

              $dataTag = $XDB->GetData();

  GetDataXMLNS() - returns a string with the namespace of the data
                   for this , if one exists.

                   $xmlns = $XDB->GetDataXMLNS();

=head2 Creation functions

  SetXDB(to=>string|JID,    - set multiple fields in the  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  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:[e-mail], 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:[e-mail], 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->SetAction("foo");

  SetMatch(string) - sets the error code of the .

                     $XDB->SetMatch("foo");

  SetErrorCode(string) - sets the error code of the .

                         $XDB->SetErrorCode(403);

  SetError(string) - sets the error string of the .

                     $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");
