NAME

Net::Jabber::Query::Version - Jabber IQ Version Module

SYNOPSIS

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

DESCRIPTION

  To initialize the Query with a Jabber <iq/> and then access the version
  query you must pass it the XML::Parser Tree array from the 
  Net::Jabber::Client module.  In the callback function for the iq:

    use Net::Jabber;

    sub iqCB {
      my $iq = new Net::Jabber::IQ(@_);
      my $version = $iq->GetQuery();
      .
      .
      .
    }

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

  To create a new Query version to send to the server:

    use Net::Jabber;

    $client = new Net::Jabber::Client();
    ...

    $iq = new Net::Jabber::IQ();
    $version = $iq->NewQuery("jabber:iq:version");
    ...

    $client->Send($iq);

  Using $version 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

    $name = $version->GetName();
    $ver  = $version->GetVer();
    $os   = $version->GetOS();

Creation functions

    $version->SetVersion(name=>'Net::Jabber',
                         ver=>'1.0',
                         os=>'Perl');

    $version->SetName('JabberClient');
    $version->SetVer('0.1');
    $version->SetOS('Perl/Tk');

Test functions

    $test = $version->DefinedName();
    $test = $version->DefinedVer();
    $test = $version->DefinedOS();

METHODS

Retrieval functions

  GetName() - returns a string with the name in the <query/>.

  GetVer() - returns a string with the version in the <query/>.

  GetOS() - returns a string with the os in the <query/>.

Creation functions

  SetVersion(name=>string, - set multiple fields in the <iq/> at one
             ver=>string,    time.  This is a cumulative and over
             os=>string)     writing action.  If you set the "name" 
                             twice, the second setting is what is
                             used.  If you set the ver, and then
                             set the os then both will be in the
                             <query/> tag.  For valid settings read 
                             the specific Set functions below.

  SetName(string) - sets the name of the local client for the <query/>.

  SetVer(string) - sets the version of the local client in the <query/>.

  SetOS(string) - sets the os, or cross-platform language, of the local
                  client in the <query/>.

Test functions

  DefinedName() - returns 1 if <name/> exists in the query, 0 otherwise.

  DefinedVer() - returns 1 if <version/> exists in the query, 0 otherwise.

  DefinedOS() - returns 1 if <os/> exists in the query, 0 otherwise.
