[Swig-user] Returning int array to Java query

[<sw...@di...>]

Hi,

I'm new to SWIG. I've looked through the documentation and done some  
searching on-line but I'm rather baffled as to how to return an array  
of int to Java. It's probably easy to do but I'm not sure how to go  
about it and I haven't so far found any nice, simple examples.

The C++ function I have is:

int* blurImage(int* buff, int w, int h)


and my blur.i file contains:

%module blur
%include <arrays_java.i>
  %{
  /* Put header files here or function declarations like below */
  extern int *blurImage(int buff[], int w, int h);
  %}

  extern int *blurImage(int buff[], int w, int h);



However, this isn't really what I want. I don't want a pointer to an  
int, I want to be able to assign to a Java array:

int[] buffer = <some array of ints>
int[] buffer1 = blur.blurImage(buffer, 10, 10);


How do I wrap the array and return it as a Java array?

Thanks.
