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.

Determines index of this cargospec.

Returns

index (in the CargoSpec::array array)

IsValid()

bool CargoSpec::IsValid ( ) const

inline

Tests for validity of this cargospec.

Returns

is this cargospec valid?

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 93 of file cargotype.cpp.

SetupCargoForClimate

void SetupCargoForClimate ( LandscapeID  l )

friend

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

Parameters

l

Landscape

Definition at line 48 of file cargotype.cpp.

Field Documentation

classes

CargoClasses CargoSpec::classes

Classes of this cargo type.
