=head1 DESCRIPTION |
| 46 |
|
| 47 |
This module handles all tasks of in band registration that are possible and |
| 48 |
specified by XEP-0077. It's mainly a helper class that eases some tasks such |
| 49 |
as submitting and retrieving a form. |

This is the constructor for a registration object. |

=over 4 |
| 62 |
|
| 63 |
=item connection |
| 64 |
|
| 65 |
This must be a L<Net::XMPP2::Connection> (or some other subclass of that) object. |
| 66 |
|
| 67 |
This argument is required. |

| 86 |
=item B<send_registration_request ($cb)> |
| 87 |
|
| 88 |
This method sends a register form request. |
| 89 |
C<$cb> will be called when either the form arrived or |
| 90 |
an error occured. |
| 91 |
|
| 92 |
The first argument of C<$cb> is always C<$self>. |
| 93 |
If the form arrived the second argument of C<$cb> will be |
| 94 |
a L<Net::XMPP2::Ext::RegisterForm> object. |
| 95 |
If an error occured the second argument will be undef |
| 96 |
and the third argument will be a L<Net::XMPP2::Error::Register> |
| 97 |
object. |
| 98 |
|
| 99 |
For hints how L<Net::XMPP2::Ext::RegisterForm> should be filled |
| 100 |
out look in XEP-0077. Either you have legacy form fields, out of band |
| 101 |
data or a data form. |
| 102 |
|
| 103 |
See also L<try_fillout_registration> in L<Net::XMPP2::Ext::RegisterForm>. |

=item B<submit_form ($form, $cb)> |
| 197 |
|
| 198 |
This method submits the C<$form> which should be of |
| 199 |
type L<Net::XMPP2::Ext::RegisterForm> and should be an answer |
| 200 |
form. |
| 201 |
|
| 202 |
C<$con> is the connection on which to send this form. |
| 203 |
|
| 204 |
C<$cb> is the callback that will be called once the form has been submitted and |
| 205 |
either an error or success was received. The first argument to the callback |
| 206 |
will be the L<Net::XMPP2::Ext::Registration> object, the second will be a |
| 207 |
boolean value that is true when the form was successfully transmitted and |
| 208 |
everything is fine. If the second argument is false then the third argument is |
| 209 |
a L<Net::XMPP2::Error::Register> object. If the error contained a data form |
| 210 |
which is required to successfully make the request then the fourth argument |
| 211 |
will be a L<Net::XMPP2::Ext::RegisterForm> which you should fill out and send |
| 212 |
again with C<submit_form>. |
| 213 |
|
| 214 |
For the semantics of such an error form see also XEP-0077. |
