837 | =head2 EXTENSION DATABASE SUPPORT |
|
|
838 | |
|
|
839 | Crossfire maintains a very simple database for extension use. It can |
|
|
840 | currently store anything that can be serialised using Storable, which |
|
|
841 | excludes objects. |
|
|
842 | |
|
|
843 | The parameter C<$family> should best start with the name of the extension |
|
|
844 | using it, it should be unique. |
|
|
845 | |
|
|
846 | =over 4 |
|
|
847 | |
|
|
848 | =item $hashref = cf::db_get $family |
|
|
849 | |
|
|
850 | Return a hashref for use by the extension C<$family>, which can be |
|
|
851 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
852 | C<cf::db_sync>. |
|
|
853 | |
|
|
854 | =item $value = cf::db_get $family => $key |
|
|
855 | |
|
|
856 | Returns a single value from the database |
|
|
857 | |
|
|
858 | =item cf::db_put $family => $hashref |
|
|
859 | |
|
|
860 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
861 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
862 | |
|
|
863 | =item cf::db_put $family => $key => $value |
|
|
864 | |
|
|
865 | Stores the given C<$value> in the family hash. Updates are delayed, if you |
|
|
866 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
867 | |
|
|
868 | =item cf::db_dirty |
|
|
869 | |
|
|
870 | Marks the database as dirty, to be updated at a later time. |
