Class TrackSegment

java.lang.Object

io.jenetics.jpx.TrackSegment

All Implemented Interfaces:

Serializable, Iterable<WayPoint>

public final class TrackSegment
extends Object
implements Iterable<WayPoint>, Serializable

A Track Segment holds a list of Track Points which are logically connected in order. To represent a single GPS track where GPS reception was lost, or the GPS receiver was turned off, start a new Track Segment for each continuous span of track data.
