=head2 join_jid ($node, $domain, $resource) |
| 43 |
|
|
|
| 44 |
|
|
This function joins the parts C<$node>, C<$domain> and C<$resource> |
| 45 |
|
|
to a full jid and applies stringprep profiles. If the profiles couldn't |
| 46 |
|
|
be applied undef will be returned. |

|
|
=head2 stringprep_jid ($jid) |
| 73 |
|
|
|
| 74 |
|
|
This applies stringprep to all parts of the jid according to the RFC 3920. |
| 75 |
|
|
Use this if you want to compare two jids like this: |
| 76 |
|
|
|
| 77 |
|
|
stringprep_jid ($jid_a) eq stringprep_jid ($jid_b) |
| 78 |
|
|
|
| 79 |
|
|
This function returns undef if the C<$jid> couldn't successfully be parsed |
| 80 |
|
|
and the preparations done. |
