Class 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.
