Returns an array reference. |

|

=item C<link_to_record $record, %params>
|

|
| 206 | 215 |
Will create an entry in the table C<record_links> with the C<from> |
| 207 | 216 |
side being C<$self> and the C<to> side being C<$record>. Will only |
| 208 | 217 |
insert a new entry if such a link does not already exist. |
| 209 | 218 |
|
| 210 |
Returns either the existing link or the newly created one as an |
|
| 211 |
instance of C<SL::DB::RecordLink>. |
|
| 219 |
If C<$params{bidirectional}> is trueish then another link will be
|
|
| 220 |
created with the roles of C<from> and C<to> reversed. This link will |
|
| 221 |
also only be created if it doesn't exist already. |
|
| 222 |
|
|
| 223 |
In scalar contenxt returns either the existing link or the newly |
|
| 224 |
created one as an instance of C<SL::DB::RecordLink>. In array context |
|
| 225 |
it returns an array of links (one entry if C<$params{bidirectional}>
|
|
| 226 |
is falsish and two entries if it is trueish). |
