Net::XMPP::IQ3pm

Usage

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

Overview

  Net::XMPP::IQ differs from the other Net::XMPP::* modules in that
  the XMLNS of the query is split out into a submodule under
  IQ.  For specifics on each module please view the documentation
  for the Net::XMPP::Namespaces module.
  A Net::XMPP::IQ 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 this information, like if you created a Client that connects to
  two servers at once, or for writing a mini server.
    use Net::XMPP;
    sub iq {
      my ($sid,$IQ) = @_;
      .
      .
      my $reply = $IQ->Reply();
      my $replyQuery->GetQuery();
      .
    }
  You now have access to all of the retrieval functions available.
  To create a new iq to send to the server:
    use Net::XMPP;
    $IQ = Net::XMPP::IQ->new();
    $IQType = $IQ->NewChild( type );
    $IQType->SetXXXXX("yyyyy");
  Now you can call the creation functions for the IQ, and for the
  <query/> on the new query object itself.  See below for the <iq/>
  functions, and in each query module for those functions.

Methods

  Reply(%args) - Creates a return <iq/> with the to and from
                 filled in correctly, and a query object already
                 added in.  The %args that you pass are passed
                 to SetIQ() and will overwrite the IQ settings
                 that Reply sets.

  GetTo()      - returns either a string with the JID, or a
  GetTo("jid")   Net::XMPP::JID object for the person who is
                 going to receive the <iq/>.  To get the JID
                 object set the string to "jid", otherwise leave
                 blank for the text string.
                 $to    = $IQ->GetTo();
                 $toJID = $IQ->GetTo("jid");
  GetFrom()      -  returns either a string with the JID, or a
  GetFrom("jid")    Net::XMPP::JID object for the person who
                    sent the <iq/>.  To get the JID object set
                    the string to "jid", otherwise leave blank for the
                    text string.
                    $from    = $IQ->GetFrom();
                    $fromJID = $IQ->GetFrom("jid");
  GetType() - returns a string with the type <iq/> this is.
              $type = $IQ->GetType();
  GetID() - returns an integer with the id of the <iq/>.
            $id = $IQ->GetID();
  GetError() - returns a string with the text description of the error.
               $error = $IQ->GetError();
  GetErrorCode() - returns a string with the code of error.
                   $errorCode = $IQ->GetErrorCode();
  GetQuery() - returns a Net::XMPP::Stanza object that contains the data
               in the query of the <iq/>.  Basically, it returns the
               first child in the <iq/>.
               $query = $IQ->GetQuery();
  GetQueryXMLNS() - returns a string with the namespace of the query
                    for this <iq/>, if one exists.
                    $xmlns = $IQ->GetQueryXMLNS();

  SetIQ(to=>string|JID,    - set multiple fields in the <iq/> 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
        errorcode=>string,   what is used.  If you set the status, and
        error=>string)       then set the priority then both will be in
                             the <iq/> tag.  For valid settings read the
                             specific Set functions below.
                             $IQ->SetIQ(type=>"get",
                                        to=>"bob\@jabber.org");
                             $IQ->SetIQ(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.  [email protected], etc...)
                  $IQ->SetTo("bob\@jabber.org");
  SetFrom(string) - sets the from attribute.  You can either pass a
  SetFrom(JID)      string or a JID object.  They must be a valid JIDs
                    or the server will return an error message.
                    (ie.  [email protected], etc...)
                    $IQ->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
                    $IQ->SetType("set");
  SetErrorCode(string) - sets the error code of the <iq/>.
                         $IQ->SetErrorCode(403);
  SetError(string) - sets the error string of the <iq/>.
                     $IQ->SetError("Permission Denied");
  NewChild(string) - creates a new Net::XMPP::Stanza 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
                     IQ module.  For more information please read the
                     documentation for Net::XMPP::Stanza.
                     $queryObj = $IQ->NewChild("jabber:iq:auth");
                     $queryObj = $IQ->NewChild("jabber:iq:roster");
  Reply(hash) - creates a new IQ object and populates the to/from
                fields.  If you specify a hash the same as with SetIQ
                then those values will override the Reply values.
                $iqReply = $IQ->Reply();
                $iqReply = $IQ->Reply(type=>"result");

  RemoveTo() - removes the to attribute from the <iq/>.
               $IQ->RemoveTo();
  RemoveFrom() - removes the from attribute from the <iq/>.
                 $IQ->RemoveFrom();
  RemoveID() - removes the id attribute from the <iq/>.
               $IQ->RemoveID();
  RemoveType() - removes the type attribute from the <iq/>.
                 $IQ->RemoveType();
  RemoveError() - removes the <error/> element from the <iq/>.
                  $IQ->RemoveError();
  RemoveErrorCode() - removes the code attribute from the <error/>
                      element in the <iq/>.
                      $IQ->RemoveErrorCode();

  DefinedTo() - returns 1 if the to attribute is defined in the <iq/>,
                0 otherwise.
                $test = $IQ->DefinedTo();
  DefinedFrom() - returns 1 if the from attribute is defined in the
                  <iq/>, 0 otherwise.
                  $test = $IQ->DefinedFrom();
  DefinedID() - returns 1 if the id attribute is defined in the <iq/>,
                0 otherwise.
                $test = $IQ->DefinedID();
  DefinedType() - returns 1 if the type attribute is defined in the
                  <iq/>, 0 otherwise.
                  $test = $IQ->DefinedType();
  DefinedError() - returns 1 if <error/> is defined in the <iq/>,
                   0 otherwise.
                   $test = $IQ->DefinedError();
  DefinedErrorCode() - returns 1 if the code attribute is defined in
                       <error/>, 0 otherwise.
                       $test = $IQ->DefinedErrorCode();
  DefinedQuery() - returns 1 if there is at least one namespaced
                   child in the object.
