Class LineStringSnapper

    java.lang.Object
      com.vividsolutions.jts.operation.overlay.snap.LineStringSnapper

    public class LineStringSnapper

extends java.lang.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.
