#include <newgrf_storage.h>
Public Member Functions | |
| PersistentStorageArray () | |
| Simply construct the array. | |
| ~PersistentStorageArray () | |
| And free all data related to it. | |
| void | ResetToZero () |
| Resets all values to zero. | |
| void | StoreValue (uint pos, int32 value) |
| Stores some value at a given position. | |
| TYPE | GetValue (uint pos) const |
| Gets the value from a given position. | |
| void | ClearChanges () |
| Discard temporary changes. | |
Public Member Functions inherited from BasePersistentStorageArray | |
| virtual | ~BasePersistentStorageArray () |
| Remove references to use. | |
Data Fields | |
| TYPE | storage [SIZE] |
| Memory to for the storage array. | |
| TYPE * | prev_storage |
| Memory to store "old" states so we can revert them on the performance of test cases for commands etc. | |
Data Fields inherited from BasePersistentStorageArray | |
| uint32 | grfid |
| GRFID associated to this persistent storage. A value of zero means "default". | |
| byte | feature |
| NOSAVE: Used to identify in the owner of the array in debug output. | |
| TileIndex | tile |

| Clear temporary changes made since the last call to SwitchMode, and set whether subsequent changes shall be persistent or temporary. | |
Static Protected Member Functions inherited from BasePersistentStorageArray | |
| static bool | AreChangesPersistent () |
