#include <newgrf_storage.h>
Public Member Functions | |
| PersistentStorage (const uint32 new_grfid, byte feature, TileIndex tile) | |
| We don't want GCC to zero our struct! It already is zeroed and has an index! | |
Public Member Functions inherited from PersistentStorageArray< int32, 16 > | |
| 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. | |
| int32 | 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. | |
Public Member Functions inherited from Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_persistent_storage_pool > | |
| void * | operator new (size_t size) |
| Allocates space for new Titem. | |
| void * | operator new (size_t size, size_t index) |
| Allocates space for new Titem with given index. | |
| void * | operator new (size_t size, void *ptr) |
| Allocates space for new Titem at given memory address. | |
| void | operator delete (void *p) |
| Marks Titem as free. | |
Additional Inherited Members | |
Static Public Member Functions inherited from BasePersistentStorageArray | |
| static void | SwitchMode (PersistentStorageMode mode, bool ignore_prev_mode=false) |
| Clear temporary changes made since the last call to SwitchMode, and set whether subsequent changes shall be persistent or temporary. | |
Static Public Member Functions inherited from Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_persistent_storage_pool > | |
| static bool | CanAllocateItem (size_t n=1) |
| Helper functions so we can use PoolItem::Function() instead of _poolitem_pool.Function() | |
| static bool | CleaningPool () |
| Returns current state of pool cleaning - yes or no. | |
| static bool | IsValidID (size_t index) |
| Tests whether given index can be used to get valid (non-NULL) Titem. | |
| static Titem * | Get (size_t index) |
| Returns Titem with given index. | |
| static Titem * | GetIfValid (size_t index) |
| Returns Titem with given index. | |
| static size_t | GetPoolSize () |
| Returns first unused index. | |
| static size_t | GetNumItems () |
| Returns number of valid items in the pool. | |
| static void | PostDestructor (size_t index) |
| Dummy function called after destructor of each member. | |
Data Fields inherited from PersistentStorageArray< int32, 16 > | |
| int32 | storage [SIZE] |
| Memory to for the storage array. | |
| int32 * | 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 Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_persistent_storage_pool > | |
| Tindex | index |
| Index of this pool item. | |
Static Protected Member Functions inherited from BasePersistentStorageArray | |
| static bool | AreChangesPersistent () |
| Check whether currently changes to the storage shall be persistent or temporary till the next call to ClearChanges(). | |
