Class ShpPolyLineZ

java.lang.Object
  com.partnersoft.formats.shapefile.ShpPolyLineZ

All Implemented Interfaces:

Immutable, ShpShape

public class ShpPolyLineZ
extends java.lang.Object
implements ShpShape

ESRI's multiple-section, multiple part polyline in (x, y, z) space with measure factor (m).

By our definitions, a shapefile PolyLineZ entity is really a list of polyline objects. Each of these is the standard ordered series of connected vertices.
