Class EsriShapeReader

java.lang.Object
  org.progeeks.geo.EsriShapeReader

All Implemented Interfaces:

java.util.Iterator

public class EsriShapeReader
extends java.lang.Object
implements java.util.Iterator

Reads Geo shapes from an ESRI SHP file. This really belongs in a sub-package but I'm simplifying in the interest of time.
