Member Function Documentation

◆ Get()

◆ GetArraySize()

static size_t CargoSpec::GetArraySize ( )
inlinestatic

Total number of cargospecs, both valid and invalid.

Returns
length of CargoSpec::array

Definition at line 124 of file cargotype.h.

References array, and lengthof.

◆ GetCargoIcon()

SpriteID CargoSpec::GetCargoIcon ( ) const

Get sprite for showing cargo of this type.

Returns
Sprite number to use.

Definition at line 169 of file cargotype.cpp.

References GetCustomCargoSprite(), and sprite.

◆ Index()

CargoID CargoSpec::Index ( ) const
inline

Determines index of this cargospec.

Returns
index (in the CargoSpec::array array)

Definition at line 105 of file cargotype.h.

References array.

Referenced by BuildLinkStatsLegend(), and TruncateCargo().

◆ IsValid()

bool CargoSpec::IsValid ( ) const
inline

Tests for validity of this cargospec.

Returns
is this cargospec valid?
Note
assert(cs->IsValid()) can be triggered when GRF config is modified

Definition at line 115 of file cargotype.h.

References INVALID_CARGO_BITNUM.

◆ Iterate()

static IterateWrapper CargoSpec::Iterate ( size_t  from = 0)
inlinestatic

Returns an iterable ensemble of all valid CargoSpec.

Parameters
fromindex of the first CargoSpec to consider
Returns
an iterable ensemble of all valid CargoSpec

Definition at line 190 of file cargotype.h.

Referenced by FindFirstCargoWithTownAcceptanceEffect(), InitializeSortedCargoSpecs(), IndustryCargoesWindow::OnInit(), and StationResolverObject::StationResolverObject().

Friends And Related Function Documentation

◆ BuildCargoLabelMap

void BuildCargoLabelMap ( )
friend

Build cargo label map.

This is called multiple times during NewGRF initialization as cargos are defined, so that TranslateRefitMask() and GetCargoTranslation(), also used during initialization, get the correct information.

Definition at line 125 of file cargotype.cpp.

◆ SetupCargoForClimate

void SetupCargoForClimate ( LandscapeID  l)
friend

Set up the default cargo types for the given landscape type.

Parameters
lLandscape

Definition at line 62 of file cargotype.cpp.

Field Documentation

◆ classes

CargoClasses CargoSpec::classes
