Member Function Documentation

◆ GetDebugID()

uint32_t StationResolverObject::GetDebugID ( ) const
overridevirtual

Get an identifier for the item being resolved.

This function is mainly intended for the callback profiling feature, and should return an identifier recognisable by the NewGRF developer.

Reimplemented from ResolverObject.

Definition at line 575 of file newgrf_station.cpp.

References StationSpec::grf_prop, GRFFilePropsBase::local_id, station_scope, and StationScopeResolver::statspec.

◆ GetFeature()

GrfSpecFeature StationResolverObject::GetFeature ( ) const
overridevirtual

Get the feature number being resolved for.

This function is mainly intended for the callback profiling feature.

Reimplemented from ResolverObject.

Definition at line 570 of file newgrf_station.cpp.

◆ GetScope()

ScopeResolver * StationResolverObject::GetScope ( VarSpriteGroupScope  scope = VSG_SCOPE_SELF,
uint8_t  relative = 0 
)
inlineoverridevirtual

Get a resolver for the scope.

Returns
The resolver for the requested scope.

Reimplemented from ResolverObject.

Definition at line 61 of file newgrf_station.h.

References ResolverObject::GetScope(), GetTown(), station_scope, VSG_SCOPE_PARENT, and VSG_SCOPE_SELF.

Referenced by NIHStation::Resolve().

◆ GetTown()

TownScopeResolver * StationResolverObject::GetTown ( )

Get the town scope associated with a station, if it exists.

On the first call, the town scope is created (if possible).

Returns
Town scope, if available.
