/* -----------------------------------------------------------------------------
 * arrays_java.i
 *
 * These typemaps give more natural support for arrays. The typemaps are not efficient
 * as there is a lot of copying of the array values whenever the array is passed to C/C++ 
 * from Java and vice versa. The Java array is expected to be the same size as the C array.
 * An exception is thrown if they are not.
 *
 * Example usage:
 * Wrapping:
 *
 *   %include <arrays_java.i>
 *   %inline %{
 *       short FiddleSticks[3];
 *   %}
 *
 * Use from Java like this:
 *
 *   short[] fs = new short[] {10, 11, 12};
 *   example.setFiddleSticks(fs);
 *   fs = example.getFiddleSticks();
 * ----------------------------------------------------------------------------- */
