934 | =head2 EXTENSION DATABASE SUPPORT |
|
|
935 | |
|
|
936 | Crossfire maintains a very simple database for extension use. It can |
|
|
937 | currently store anything that can be serialised using Storable, which |
|
|
938 | excludes objects. |
|
|
939 | |
|
|
940 | The parameter C<$family> should best start with the name of the extension |
|
|
941 | using it, it should be unique. |
|
|
942 | |
|
|
943 | =over 4 |
|
|
944 | |
|
|
945 | =item $hashref = cf::db_get $family |
|
|
946 | |
|
|
947 | Return a hashref for use by the extension C<$family>, which can be |
|
|
948 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
949 | C<cf::db_sync>. |
|
|
950 | |
|
|
951 | =item $value = cf::db_get $family => $key |
|
|
952 | |
|
|
953 | Returns a single value from the database |
|
|
954 | |
|
|
955 | =item cf::db_put $family => $hashref |
|
|
956 | |
|
|
957 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
958 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
959 | |
|
|
960 | =item cf::db_put $family => $key => $value |
|
|
961 | |
|
|
962 | Stores the given C<$value> in the family hash. Updates are delayed, if you |
|
|
963 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
964 | |
|
|
965 | =item cf::db_dirty |
|
|
966 | |
|
|
967 | Marks the database as dirty, to be updated at a later time. |
|
|
968 | |
|
|
969 | =item cf::db_sync |
|
|
970 | |
|
|
971 | Immediately write the database to disk I<if it is dirty>. |
