929 | =head2 EXTENSION DATABASE SUPPORT |
|
|
930 | |
|
|
931 | Crossfire maintains a very simple database for extension use. It can |
|
|
932 | currently store anything that can be serialised using Storable, which |
|
|
933 | excludes objects. |
|
|
934 | |
|
|
935 | The parameter C<$family> should best start with the name of the extension |
|
|
936 | using it, it should be unique. |
|
|
937 | |
|
|
938 | =over 4 |
|
|
939 | |
|
|
940 | =item $hashref = cf::db_get $family |
|
|
941 | |
|
|
942 | Return a hashref for use by the extension C<$family>, which can be |
|
|
943 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
944 | C<cf::db_sync>. |
|
|
945 | |
|
|
946 | =item $value = cf::db_get $family => $key |
|
|
947 | |
|
|
948 | Returns a single value from the database |
|
|
949 | |
|
|
950 | =item cf::db_put $family => $hashref |
|
|
951 | |
|
|
952 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
953 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
954 | |
|
|
955 | =item cf::db_put $family => $key => $value |
|
|
956 | |
|
|
957 | Stores the given C<$value> in the family hash. Updates are delayed, if you |
|
|
958 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
959 | |
|
|

|
|
961 | |
|
