NAME

Net::XMPP::Message - XMPP Message Module

SYNOPSIS

Net::XMPP::Message is a companion to the Net::XMPP module.
It provides the user a simple interface to set and retrieve all
parts of an XMPP Message.

DESCRIPTION

A Net::XMPP::Message object is passed to the callback function for
the message.  Also, the first argument to the callback functions is
the session ID from XML::Stream.  There are some cases where you
might want thisinformation, like if you created a Client that
connects to two servers at once, or for writing a mini server.

  use Net::XMPP;

  sub message {
    my ($sid,$Mess) = @_;
    .
    .
    .
  }

You now have access to all of the retrieval functions available.

To create a new message to send to the server:

  use Net::XMPP;

  $Mess = Net::XMPP::Message->new();

Now you can call the creation functions below to populate the tag
before sending it.

METHODS

Retrieval functions

GetTo()      - returns the value in the to='' attribute for the
GetTo("jid")   <message/>.  If you specify "jid" as an argument
               then a Net::XMPP::JID object is returned and
               you can easily parse the parts of the JID.

               $to    = $Mess->GetTo();
               $toJID = $Mess->GetTo("jid");

GetFrom()      - returns the value in the from='' attribute for the
GetFrom("jid")   <message/>.  If you specify "jid" as an argument
                 then a Net::XMPP::JID object is returned and
                 you can easily parse the parts of the JID.

                 $from    = $Mess->GetFrom();
                 $fromJID = $Mess->GetFrom("jid");

GetType() - returns the type='' attribute of the <message/>.  Each
            message is one of four types:

              normal        regular message (default if type is blank)
              chat          one on one chat
              groupchat     multi-person chat
              headline      headline
              error         error message

            $type = $Mess->GetType();

GetSubject() - returns the data in the <subject/> tag.

               $subject = $Mess->GetSubject();

GetBody() - returns the data in the <body/> tag.

            $body = $Mess->GetBody();

GetThread() - returns the data in the <thread/> tag.

              $thread = $Mess->GetThread();

GetError() - returns a string with the data of the <error/> tag.

             $error = $Mess->GetError();

GetErrorCode() - returns a string with the code='' attribute of the
                 <error/> tag.

                 $errCode = $Mess->GetErrorCode();

GetTimeStamp() - returns a string that represents the time this
                 message object was created (and probably received)
                 for sending to the client.  If there is a
                 jabber:x:delay tag then that time is used to show
                 when the message was sent.

                 $date = $Mess->GetTimeStamp();

Creation functions

SetMessage(to=>string|JID,    - set multiple fields in the <message/>
           from=>string|JID,    at one time.  This is a cumulative
           type=>string,        and over writing action.  If you set
           subject=>string,     the "to" attribute twice, the second
           body=>string,        setting is what is used.  If you set
           thread=>string,      the subject, and then set the body
           errorcode=>string,   then both will be in the <message/>
           error=>string)       tag.  For valid settings read the
                                specific Set functions below.

                          $Mess->SetMessage(TO=>"bob\@jabber.org",
                                            Subject=>"Lunch",
                                            BoDy=>"Let's do lunch!");
                          $Mess->SetMessage(to=>"bob\@jabber.org",
                                            from=>"jabber.org",
                                            errorcode=>404,
                                            error=>"Not found");

SetTo(string) - sets the to='' attribute.  You can either pass
SetTo(JID)      a string or a JID object.  They must be valid JIDs
                or the server will return an error message.
                (ie.  bob@jabber.org/Work)

                $Mess->SetTo("test\@jabber.org");

SetFrom(string) - sets the from='' attribute.  You can either pass
SetFrom(JID)      a string or a JID object.  They must be valid JIDs
                  or the server will return an error message. (ie.
                  jabber:bob@jabber.org/Work) This field is not
                  required if you are writing a Client since the
                  server will put the JID of your connection in
                  there to prevent spamming.

                  $Mess->SetFrom("me\@jabber.org");

SetType(string) - sets the type attribute.  Valid settings are:

                    normal         regular message (default if blank)
                    chat           one one one chat style message
                    groupchat      multi-person chatroom message
                    headline       news headline, stock ticker, etc...
                    error          error message

                  $Mess->SetType("groupchat");

SetSubject(string) - sets the subject of the <message/>.

                     $Mess->SetSubject("This is a test");

SetBody(string) - sets the body of the <message/>.

                  $Mess->SetBody("To be or not to be...");

SetThread(string) - sets the thread of the <message/>.  You should
                    copy this out of the message being replied to so
                    that the thread is maintained.

                    $Mess->SetThread("AE912B3");

SetErrorCode(string) - sets the error code of the <message/>.

                       $Mess->SetErrorCode(403);

SetError(string) - sets the error string of the <message/>.

                   $Mess->SetError("Permission Denied");

Reply(hash) - creates a new Message object and populates the
              to/from, and the subject by putting "re: " in
              front.  If you specify a hash the same as with
              SetMessage then those values will override the
              Reply values.

              $Reply = $Mess->Reply();
              $Reply = $Mess->Reply(type=>"chat");
