/* -----------------------------------------------------------------------------
* arrays_javascript.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 JavaScript and vice versa. The JavaScript 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_javascript.i>
* %inline %{
* extern int FiddleSticks[3];
* %}
*
* Use from JavaScript like this:
*
* var fs = [10, 11, 12];
* example.FiddleSticks = fs;
* fs = example.FiddleSticks;
