959 | =head2 EXTENSION DATABASE SUPPORT |
|
|
960 | |
|
|
961 | Crossfire maintains a very simple database for extension use. It can |
|
|
962 | currently store anything that can be serialised using Storable, which |
|
|
963 | excludes objects. |
|
|
964 | |
|
|
965 | The parameter C<$family> should best start with the name of the extension |
|
|
966 | using it, it should be unique. |
|
|
967 | |
|
|
968 | =over 4 |
|
|
969 | |
|
|
970 | =item $hashref = cf::db_get $family |
|
|
971 | |
|
|
972 | Return a hashref for use by the extension C<$family>, which can be |
|
|
973 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
974 | C<cf::db_sync>. |
|
|
975 | |
|
|
976 | =item $value = cf::db_get $family => $key |
|
|
977 | |
|
|
978 | Returns a single value from the database |
|
|
979 | |
|
|
980 | =item cf::db_put $family => $hashref |
|
|
981 | |
|
|
982 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
983 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
984 | |
|
|
985 | =item cf::db_put $family => $key => $value |
|
|
986 | |
|
|
987 | Stores the given C<$value> in the family hash. Updates are delayed, if you |
|
|
988 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
989 | |
|
|
990 | =item cf::db_dirty |
|
|
991 | |
|
|
992 | Marks the database as dirty, to be updated at a later time. |
|
|
993 | |
|
|
994 | =item cf::db_sync |
|
|
995 | |
|
|
996 | Immediately write the database to disk I<if it is dirty>. |
