2176 | =head2 EXTENSION DATABASE SUPPORT |
|
|
2177 | |
|
|
2178 | Crossfire maintains a very simple database for extension use. It can |
|
|
2179 | currently store anything that can be serialised using Storable, which |
|
|
2180 | excludes objects. |
|
|
2181 | |
|
|
2182 | The parameter C<$family> should best start with the name of the extension |
|
|
2183 | using it, it should be unique. |
|
|
2184 | |
|
|
2185 | =over 4 |
|
|
2186 | |
|
|
2187 | =item $hashref = cf::db_get $family |
|
|
2188 | |
|
|
2189 | Return a hashref for use by the extension C<$family>, which can be |
|
|
2190 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
2191 | C<cf::db_sync>. |
|
|
2192 | |
|
|
2193 | =item $value = cf::db_get $family => $key |
|
|
2194 | |
|
|
2195 | Returns a single value from the database |
|
|
2196 | |
|
|
2197 | =item cf::db_put $family => $hashref |
|
|
2198 | |
|
|
2199 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
2200 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
2201 | |
|
|
2202 | =item cf::db_put $family => $key => $value |
|
|
2203 | |
|
|
2204 | Stores the given C<$value> in the family hash. Updates are delayed, if you |
|
|
2205 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
2206 | |
|
|
2207 | =item cf::db_dirty |
|
|
2208 | |
|
|
2209 | Marks the database as dirty, to be updated at a later time. |
|
|
2210 | |
|
|
2211 | =item cf::db_sync |
|
|
2212 | |
