Class Shapefile

java.lang.Object

com.vividsolutions.jtstest.testbuilder.io.shapefile.Shapefile

public class Shapefile
extends java.lang.Object

This class represnts an ESRI Shape file.

You construct it with a file name, and later you can read the file's propertys, i.e. Sizes, Types, and the data itself.

Copyright 1998 by James Macgill.

Modified to allow reading the shapefile as a stream Martin Davis 2005-2007 Version 1.0beta1.1 (added construct with inputstream) 1.0beta1.2 (made Shape type constants public 18/Aug/98) This class supports the Shape file as set out in :-
"ESRI(r) Shapefile - A Technical Description"
'An ESRI White Paper . May 1997'
