Function Documentation

BruteForceFindRoadPositionsStrategy()

std::vector< maliput::api::RoadPositionResult > BruteForceFindRoadPositionsStrategy	(	const maliput::api::RoadGeometry *	rg,
		const maliput::api::InertialPosition &	inertial_position,
		double	radius
	)

Provides a brute force implementation of RoadGeometry::FindRoadPosition() that exhaustively calls ToLanePosition() on all lanes and checks distance with radius.

Note

Maliput backends could avoid implementing a custom implementation of RoadGeometry::FindRoadPositions() that knows about the geometry internals by forwarding calls to this function. On the contrary, backends might decide not to use this function because, for example, time complexity which is at least O(n^3).

Parameters

rg	The RoadGeometry over all these operations are performed. It must not be nullptr.
inertial_position	The inertial position to convert into one or more RoadPositions.
radius	The maximum distance from inertial_position to search. It must not be negative.

Returns

A vector of RoadPositionResults representing the possible RoadPositions.

Exceptions

maliput::common::assertion_error	If rg is nullptr, or any entity within it is nullptr.
maliput::common::assertion_error	If radius is negative.

FilterRoadPositionResults()

std::vector< api::RoadPositionResult > FilterRoadPositionResults	(	const std::vector< api::RoadPositionResult > &	road_position_results,
		const std::function< bool(const api::RoadPositionResult &)> &	filter
	)

Returns

A filtered version road_position_results by applying filter to each item of road_position_results. When filter returns true, the item is preserved.

Parameters

road_position_results	A vector of RoadPositionResults to be filtered. Typically, it is the result of calling api::RoadGeometry::FindRoadPositions().
filter	An arbitrary functor to filter road_position_results.

IsNewRoadPositionResultCloser()

bool IsNewRoadPositionResultCloser	(	const maliput::api::RoadPositionResult &	new_road_position_result,
		const maliput::api::RoadPositionResult &	road_position_result
	)

Compares two maliput::api::RoadPositionResults and determines whether new_road_position_result is closer to road_position_result.

See also

maliput::api::RoadPosition::ToRoadPosition() for a clear definition of how the comparison must be performed.

Parameters

new_road_position_result	A maliput::api::RoadPositionResult to compare.
road_position_result	The reference maliput::api::RoadPositionResult to compare.

Returns

true When new_road_position_result is closer than road_position_result.
