#include <subsidy_base.h>
Public Member Functions | |
Subsidy () | |
We need an (empty) constructor so struct isn't zeroed (as C++ standard states) | |
~Subsidy () | |
(Empty) destructor has to be defined else operator delete might be called with nullptr parameter | |
bool | IsAwarded () const |
Tests whether this subsidy has been awarded to someone. More... | |
void | AwardTo (CompanyID company) |
Marks subsidy as awarded, creates news and AI event. More... | |
Public Member Functions inherited from Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_subsidy_pool > | |
void * | operator new (size_t size) |
Allocates space for new Titem. More... | |
void * | operator new (size_t size, size_t index) |
Allocates space for new Titem with given index. More... | |
void * | operator new (size_t, void *ptr) |
Allocates space for new Titem at given memory address. More... | |
void | operator delete (void *p) |
Marks Titem as free. More... | |
Data Fields | |
CargoID | cargo_type |
Cargo type involved in this subsidy, INVALID_CARGO for invalid subsidy. | |
uint16_t | remaining |
Remaining months when this subsidy is valid. | |
CompanyID | awarded |
Subsidy is awarded to this company; INVALID_COMPANY if it's not awarded to anyone. | |
SourceType | src_type |
Source of subsidised path (SourceType::Industry or SourceType::Town) | |
SourceType | dst_type |
Destination of subsidised path (SourceType::Industry or SourceType::Town) | |
SourceID | src |
Index of source. Either TownID or IndustryID. | |
SourceID | dst |
Index of destination. Either TownID or IndustryID. | |
Data Fields inherited from Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_subsidy_pool > | |

typedef struct Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero > | Pool |
Type of the pool this item is going to be part of. | |
Static Public Member Functions inherited from Pool< Titem, Tindex, Tgrowth_step, Tmax_size, Tpool_type, Tcache, Tzero >::PoolItem<&_subsidy_pool > | |
static bool | CanAllocateItem (size_t n=1) |
Helper functions so we can use PoolItem::Function() instead of _poolitem_pool.Function() More... | |
static bool | CleaningPool () |
Returns current state of pool cleaning - yes or no. More... | |
static bool | IsValidID (size_t index) |
Tests whether given index can be used to get valid (non-nullptr) Titem. More... | |
static Titem * | Get (size_t index) |
Returns Titem with given index. More... | |
static Titem * | GetIfValid (size_t index) |
Returns Titem with given index. More... | |
static size_t | GetPoolSize () |
Returns first unused index. More... | |
static size_t | GetNumItems () |
Returns number of valid items in the pool. More... | |
static void | PostDestructor ([[maybe_unused]] size_t index) |
Dummy function called after destructor of each member. More... | |
static Pool::IterateWrapper< Titem > | Iterate (size_t from=0) |
Returns an iterable ensemble of all valid Titem. More... | |
