Inheritance diagram for Subsidy:

Public Member Functions
	Subsidy ()
	We need an (empty) constructor so struct isn't zeroed (as C++ standard states)
	Subsidy (CargoType cargo_type, Source src, Source dst, uint16_t remaining)
	~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.
void	AwardTo (CompanyID company)
	Marks subsidy as awarded, creates news and AI event.
Public Member Functions inherited from Pool< Titem, Tindex, Tgrowth_step, Tpool_type, Tcache >::PoolItem<&_subsidy_pool >
void *	operator new (size_t size)
	Allocates space for new Titem.
void *	operator new (size_t size, Tindex index)
	Allocates space for new Titem with given index.
void *	operator new (size_t, void *ptr)
	Allocates space for new Titem at given memory address.
void	operator delete (void *p, size_t size)
	Marks Titem as free.

Data Fields
CargoType	cargo_type = INVALID_CARGO
	Cargo type involved in this subsidy, INVALID_CARGO for invalid subsidy.
uint16_t	remaining = 0
	Remaining months when this subsidy is valid.
CompanyID	awarded = CompanyID::Invalid()
	Subsidy is awarded to this company; CompanyID::Invalid() if it's not awarded to anyone.
Source	src {}
	Source of subsidised path.
Source	dst {}
	Destination of subsidised path.
Data Fields inherited from Pool< Titem, Tindex, Tgrowth_step, Tpool_type, Tcache >::PoolItem<&_subsidy_pool >
Tindex	index
	Index of this pool item.

Additional Inherited Members
Public Types inherited from Pool< Titem, Tindex, Tgrowth_step, Tpool_type, Tcache >::PoolItem<&_subsidy_pool >
typedef struct Pool< Titem, Tindex, Tgrowth_step, Tpool_type, Tcache >	Pool
	Type of the pool this item is going to be part of.
Static Public Member Functions inherited from Pool< Titem, Tindex, Tgrowth_step, Tpool_type, Tcache >::PoolItem<&_subsidy_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 (auto index)
	Tests whether given index can be used to get valid (non-nullptr) Titem.
static Titem *	Get (auto index)
	Returns Titem with given index.
static Titem *	GetIfValid (auto 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.
static Pool::IterateWrapper< Titem >	Iterate (size_t from=0)
	Returns an iterable ensemble of all valid Titem.
