Class ShapeWriter

java.lang.Object
  org.progeeks.geo.esri.ShapeWriter

public class ShapeWriter
extends java.lang.Object

Writes esri.shape meta object to an ESRI SHP file (also creates the DBF and SHX) files). Note that because the file header contains the file size and bounding box, the file will not be correct until this writer is closed. Failure to close this writer will result in an invalid shape file.
