822 | =head2 EXTENSION DATABASE SUPPORT |
|
|
823 | |
|
|
824 | Crossfire maintains a very simple database for extension use. It can |
|
|
825 | currently store anything that can be serialised using Storable, which |
|
|
826 | excludes objects. |
|
|
827 | |
|
|
828 | The parameter C<$family> should best start with the name of the extension |
|
|
829 | using it, it should be unique. |

|
|
832 | |
|
|
833 | =item $hashref = cf::db_get $family |
|
|
834 | |
|
|
835 | Return a hashref for use by the extension C<$family>, which can be |
|
|
836 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
837 | C<cf::db_sync>. |
|
|
838 | |
|
|
839 | =item $value = cf::db_get $family => $key |
|

|
|
842 | |
|
|
843 | =item cf::db_put $family => $hashref |
|
|
844 | |
|
|
845 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
846 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
847 | |
|
|
848 | =item cf::db_put $family => $key => $value |
|
|
849 | |
|

|
|
852 | |
|
|
853 | =item cf::db_dirty |
|
|
854 | |
|
