Net::Jabber::Dialback::Verify - Jabber Dialback Verify Module

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

  To initialize the Verify with a Jabber <db:*/> you must pass it
  the XML::Stream hash.  For example:

    my $dialback = new Net::Jabber::Dialback::Verify(%hash);

  There has been a change from the old way of handling the callbacks.
  You no longer have to do the above yourself, a NJ::Dialback::Verify
  object is passed to the callback function for the message.  Also,
  the first argument to the callback functions is the session ID from
  XML::Streams.  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::Jabber qw(Server);

    sub dialbackVerify {
      my ($sid,$Verify) = @_;
      .
      .
      .
    }

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

  To create a new dialback to send to the server:

    use Net::Jabber qw(Server);

    $Verify = new Net::Jabber::Dialback::Verify();

  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.

    $to         = $Verify->GetTo();
    $from       = $Verify->GetFrom();
    $type       = $Verify->GetType();
    $id         = $Verify->GetID();
    $data       = $Verify->GetData();

    $str        = $Verify->GetXML();
    @dialback   = $Verify->GetTree();

    $Verify->SetVerify(from=>"jabber.org",
                       to=>"jabber.com",
                       id=>id,
                       data=>key);
    $Verify->SetTo("jabber.org");
    $Verify->SetFrom("jabber.com");
    $Verify->SetType("valid");
    $Verify->SetID(id);
    $Verify->SetData(key);

    $test = $Verify->DefinedTo();
    $test = $Verify->DefinedFrom();
    $test = $Verify->DefinedType();
    $test = $Verify->DefinedID();

  GetTo() -  returns a string with server that the <db:verify/> is being
             sent to.

  GetFrom() -  returns a string with server that the <db:verify/> is being
               sent from.

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

  GetID() - returns a string with the id <db:verify/> this is.

  GetData() - returns a string with the cdata of the <db:verify/>.

  GetXML() - returns the XML string that represents the <db:verify/>.
             This is used by the Send() function in Server.pm to send
             this object as a Jabber Dialback Verify.

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

  SetVerify(to=>string,   - set multiple fields in the <db:verify/>
            from=>string,   at one time.  This is a cumulative
            type=>string,   and over writing action.  If you set
            id=>string,     the "from" attribute twice, the second
            data=>string)   setting is what is used.  If you set
                            the type, and then set the data
                            then both will be in the <db:verify/>
                            tag.  For valid settings read the
                            specific Set functions below.

  SetTo(string) - sets the to attribute.

  SetFrom(string) - sets the from attribute.

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

                    valid
                    invalid

  SetID(string) - sets the id attribute.

  SetData(string) - sets the cdata of the <db:verify/>.

  DefinedTo() - returns 1 if the to attribute is defined in the 
                <db:verify/>, 0 otherwise.

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

  DefinedType() - returns 1 if the type attribute is defined in the 
                  <db:verify/>, 0 otherwise.

  DefinedID() - returns 1 if the id attribute is defined in the 
                  <db:verify/>, 0 otherwise.
