Public Member Functions

 CargoList ()
 Create the cargo list.
 
 ~CargoList ()
 Destroy the cargolist ("frees" all cargo packets).
 
void OnCleanPool ()
 Empty the cargo list, but don't free the cargo packets; the cargo packets are cleaned by CargoPacket's CleanPool.
 
const Tcont * Packets () const
 Returns a pointer to the cargo packet list (so you can iterate over it etc). More...
 
uint PeriodsInTransit () const
 Returns average number of cargo aging periods in transit for a cargo entity. More...
 
void InvalidateCache ()
 Invalidates the cached data and rebuilds it.
 

Protected Member Functions

void AddToCache (const CargoPacket *cp)
 Update the cache to reflect adding of this packet. More...
 
void RemoveFromCache (const CargoPacket *cp, uint count)
 Update the cached values to reflect the removal of this packet or part of it. More...
 

Static Protected Member Functions

static bool TryMerge (CargoPacket *cp, CargoPacket *icp)
 Tries to merge the second packet into the first and return if that was successful. More...
 

Protected Attributes

uint count
 Cache for the number of cargo entities.
 
uint64_t cargo_periods_in_transit
 Cache for the sum of number of cargo aging periods in transit of each entity; comparable to man-hours.
 
Tcont packets
 The cargo packets in this list.
