java.lang.Object
org.locationtech.jts.operation.overlay.snap.LineStringSnapper

public class LineStringSnapper extends Object
Snaps the vertices and segments of a LineString to a set of target snap vertices. A snap distance tolerance is used to control where snapping is performed.

The implementation handles empty geometry and empty snap vertex sets.
