Public Types | |
enum | MoveToAction { MTA_BEGIN = 0 , MTA_TRANSFER = 0 , MTA_DELIVER , MTA_KEEP , MTA_LOAD , MTA_END , NUM_MOVE_TO_ACTION = MTA_END } |
Kind of actions that could be done with packets on move. More... | |
typedef Tcont::iterator | Iterator |
The iterator for our container. | |
typedef Tcont::reverse_iterator | ReverseIterator |
The reverse iterator for our container. | |
typedef Tcont::const_iterator | ConstIterator |
The const iterator for our container. | |
typedef Tcont::const_reverse_iterator | ConstReverseIterator |
The const reverse iterator for our container. | |
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. | |
Simple collection class for a list of cargo packets.
Tinst | Actual instantiation of this cargo list. |
