NAME

Net::Jabber::Message - Jabber Message Module

SYNOPSIS

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

DESCRIPTION

  To initialize the Message with a Jabber <message/> you must pass it 
  the XML::Parser Tree array from the Net::Jabber::Client module.  In the
  callback function for the message:

    use Net::Jabber;

    sub message {
      my $message = new Net::Jabber::Message(@_);
      .
      .
      .
    }

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

  To create a new message to send to the server:

    use Net::Jabber;

    $Mess = new Net::Jabber::Message();

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

  For more information about the array format being passed to the CallBack
  please read the Net::Jabber::Client documentation.

Retrieval functions

    $to       = $Mess->GetTo();
    $toJID    = $Mess->GetTo("jid");
    $from     = $Mess->GetFrom();
    $fromJID  = $Mess->GetFrom("jid");
    $resource = $Mess->GetResource();
    $type     = $Mess->GetType();
    $subject  = $Mess->GetSubject();
    $body     = $Mess->GetBody();
    @body     = $Mess->GetBody("full");
    $thread   = $Mess->GetThread();
    $priority = $Mess->GetPriority();
    $error    = $Mess->GetError();
    $errType  = $Mess->GetErrorType();
    @xTags    = $Mess->GetX();
    @xTags    = $Mess->GetX("my:namespace");
    @xTrees   = $Mess->GetXTrees();
    @xTrees   = $Mess->GetXTrees("my:namespace");

    $str      = $Mess->GetXML();
    @message  = $Mess->GetTree();

Creation functions

    $Mess->SetMessage(TO=>"bob\@jabber.org/Working Bob",
                      Subject=>"Lunch",
                      BoDy=>"Let's go grab some lunch!",
                      priority=>100);
    $Mess->SetTo("Test User");
    $Mess->SetSubject("This is a test");
    $Mess->SetBody("This is a test of the emergency broadcast system...");
    $Mess->SetThread("AE912B3");
    $Mess->SetPriority(1);

    $Mess->SetMessage(to=>"bob\@jabber.org",
                      errortype=>"denied",
                      error=>"Permission Denied");
    $Mess->SetErrorType("denied");
    $Mess->SetError("Permission Denied");

    $X = $Mess->NewX("jabber:x:delay");
    $X = $Mess->NewX("my:namespace");

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 <message/>.  To get the JID
                 object set the string to "jid", otherwise leave
                 blank for the text string.

  GetFrom()      -  returns either a string with the Jabber Identifier,
  GetFrom("jid")    or a Net::Jabber::JID object for the person who
                    sent the <message/>.  To get the JID object set 
                    the string to "jid", otherwise leave blank for the 
                    text string.

  GetResource() - returns a string with the Jabber Resource of the 
                  person who sent the <message/>.

  GetType() - returns a string with the type <message/> this is.

  GetSubject() - returns a string with the subject of the <message/>.

  GetBody(string) - returns the data in the <body/> tag depending on the
                    value of the string passed to it.  The string
                    represents the mark up level to return.

                    none   returns a string with just the text of 
                           the <body/> (default)
                    full   returns an XML::Paser::Tree with everything
                           in the <body/>

  GetThread() - returns a string that represents the thread this
                <message/> belongs to.

  GetPriority() - returns an integer with the priority of the <message/>.

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

  GetErrorType() - returns a string with the type of the <error/> tag.

  GetX(string) - returns an array of Net::Jabber::X objects.  The string 
                 can either be empty or the XML Namespace you are looking
                 for.  If empty then GetX returns every <x/> tag in the 
                 <message/>.  If an XML Namespace is sent then GetX 
                 returns every <x/> tag with that Namespace.

  GetXTrees(string) - returns an array of XML::Parser::Tree objects.  The 
                      string can either be empty or the XML Namespace you 
                      are looking for.  If empty then GetXTrees returns
                      every <x/> tag in the <message/>.  If an XML
                      Namespace is sent then GetXTrees returns every
                      <x/> tag with that  Namespace.

  GetXML() - returns the XML string that represents the <message/>.
             This is used by the Send() function in Client.pm to send
             this object as a Jabber Message.

  GetTree() - returns an array that contains the <message/> tag
                 in XML::Parser Tree format.

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=>integer,      the subject, and then set the body
             priority=>string,     then both will be in the <message/>
             errortype=>string,    tag.  For valid settings read the
             error=>string)        specific Set functions below.

  SetTo(string) - sets the to attribute.  You can either pass a string
  SetTo(JID)      or a JID object.  They must be valid Jabber 
                  Identifiers or the server will return an error message.
                  (ie.  jabber:bob@jabber.org/Silent Bob, etc...)

  SetFrom(string) - sets the from attribute.  You can either pass a string
  SetFrom(JID)      or a JID object.  They must be valid Jabber 
                    Identifiers or the server will return an error message.
                    (ie.  jabber:bob@jabber.org/Silent Bob, etc...)

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

                    normal         defines a normal message
                    chat           defines a chat style message
                    groupchat      defines a chatroom message

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

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

  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.

  SetPriority(integer) - sets the priority of this <message/>.  The 
                         higher the priority the more likely the client
                         will deliver the message, even if the user has
                         specified no messages.

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

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

  NewX(string) - creates a new Net::Jabber::X 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 X module.  For more information
                 please read the documentation for Net::Jabber::X.
