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 555 of file newgrf_station.cpp.

References StationSpec::grf_prop, GRFFilePropsBase< Tcnt >::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 550 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 60 of file newgrf_station.h.

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

◆ 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.

Definition at line 255 of file newgrf_station.cpp.

References ClosestTownFromTile(), INVALID_TILE, StationScopeResolver::st, station_scope, StationScopeResolver::tile, BaseStation::town, and town_scope.

Referenced by GetScope().

◆ ResolveReal()

const SpriteGroup * StationResolverObject::ResolveReal ( const RealSpriteGroup * group ) const

overridevirtual

Get the real sprites of the grf.

Parameters

group Group to get.

Returns: The available sprite group.

Reimplemented from ResolverObject.

Definition at line 505 of file newgrf_station.cpp.
