 * Name:     osr_java.i
 * Project:  GDAL SWIG Interface
 * Purpose:  Typemaps for Java bindings
 * Author:   Benjamin Collins, The MITRE Corporation
 *
 *
 * $Log$
 * Revision 1.2  2006/02/16 17:21:12  collinsb
 * Updates to Java bindings to keep the code from halting execution if the native libraries cannot be found.
 *
 * Revision 1.1  2006/02/02 20:56:07  collinsb
 * Added Java specific typemap code
