NAME

Net::XMPP::IQ - XMPP Info/Query Module

SYNOPSIS

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.

DESCRIPTION

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

General functions

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.

Retrieval functions

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();

Creation functions

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.  bob@jabber.org, 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.  bob@jabber.org, 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");

Removal functions

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();

Test functions

              0 otherwise.

              $test = $IQ->DefinedTo();

DefinedFrom() - returns 1 if the from attribute is defined in the
                <iq/>, 0 otherwise.

                <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.
