addCluster()

void dsf::mdt::Trajectory::addCluster

(

PointsCluster &&

cluster

)

Add a PointsCluster to the trajectory.

Parameters

cluster

The PointsCluster to add.

addPoint()

void dsf::mdt::Trajectory::addPoint	(	std::time_t	timestamp,
		dsf::geometry::Point const &	point )

Add a point with timestamp to the trajectory.

Parameters

timestamp	The timestamp of the activity point.
point	The geometric point of the activity point.

empty()

bool dsf::mdt::Trajectory::empty ( ) const

inlinenoexcept

Check if the trajectory is empty.

Returns

True if the trajectory has no points, false otherwise.

filter()

void dsf::mdt::Trajectory::filter	(	double const	cluster_radius_km,
		double const	max_speed_kph )

Filter the trajectory to identify stop points based on clustering and speed criteria.

Parameters

cluster_radius_km	The radius (in kilometers) to use for clustering points.
max_speed_kph	The max allowed speed (in km/h) to consider a cluster as a stop point.

points()

auto const & dsf::mdt::Trajectory::points ( ) const

inlinenoexcept

Get the underlying points map.

Returns

A const reference to the map of points.

size()

std::size_t dsf::mdt::Trajectory::size ( ) const

inlinenoexcept

Get the number of points in the trajectory.

Returns

The size of the trajectory.
