[Swig-user] FAQ about arrays of structs

[Dan K. <ka...@tx...>]

I apologize for asking what I know is a FAQ.  However, I've been reading the
answers and haven't been able to piece together a working solution.  

 

I want to call a C function from Java that takes as an argument a pointer to
a struct, representing an array of undefined length.  From reading the
documentation and the web archives, I understand that I want to use
JAVA_ARRAYSOFCLASSES and/or typemaps in some combination.  Any pointers to a
complete example (or direct answers) would be greatly appreciated.

 

Here's the simplified version of the header file for the C function I want
to call.  (Note that I am not the author of the header file, so don't have
complete control over its form.)

 

struct

{

  float x;

  float y;

} float2;

 

typedef float2 Complex;

 

extern "C" int someFunc(Complex *in, Complex *out, int length);

 

Given that header file, how would one structure the .i file so that the
function could be called in a reasonable manner from Java?

 

Thanks in advance,

 

-Dan
