LineStringSnapper

java.lang.Object
- org.meteoinfo.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.
