447 | Just because you have a perl object does not mean that the corresponding |
|
|
448 | C-level object still exists. If you try to access an object that has no |
|
|
449 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
450 | can be used to test for existence of the C object part without causing an |
|
|
451 | exception. |

956 | =head2 EXTENSION DATABASE SUPPORT |
|
|
957 | |
|
|
958 | Crossfire maintains a very simple database for extension use. It can |
|
|
959 | currently store anything that can be serialised using Storable, which |
|
|
960 | excludes objects. |
|
|
961 | |
|
|
962 | The parameter C<$family> should best start with the name of the extension |
|
|
963 | using it, it should be unique. |
|

|
|

|
966 | |
|
|
967 | =item $hashref = cf::db_get $family |
|
|
968 | |
|
|
969 | Return a hashref for use by the extension C<$family>, which can be |
|
|
970 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
971 | C<cf::db_sync>. |
|
|
972 | |
|
|
973 | =item $value = cf::db_get $family => $key |

|
|
976 | |
|
|
977 | =item cf::db_put $family => $hashref |
|
|
978 | |
|
|
979 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
980 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
981 | |
|
|
982 | =item cf::db_put $family => $key => $value |
|
|
983 | |
|
|
984 | Stores the given C<$value> in the family hash. Updates are delayed, if you |

985 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
986 | |
