[Swig-user] %catches question

[Charlie S. <cf...@in...>]

Curious about the new %catches directive.

Say I have code like this:

%exception {
    try {
        $action
    }
  catch (geos::AssertionFailedException *e) {
            %raise(SWIG_NewPointerObj(e, 
SWIGTYPE_p_geos__AssertionFailedException, SWIG_POINTER_OWN), 
"geos::AssertionFailedException", 
SWIGTYPE_p_geos__AssertionFailedException);
  }
  catch (geos::IllegalArgumentException *e) {
            %raise(SWIG_NewPointerObj(e, 
SWIGTYPE_p_geos__IllegalArgumentException, SWIG_POINTER_OWN), 
"geos::IllegalArgumentException", 
SWIGTYPE_p_geos__IllegalArgumentException);
  }
.....(skipping a few more exceptions)


I tried doing something like this instead:

%catches(geos::AssertionFailedException, geos::IllegalArgumentException)

Where this would apply to every generated method, just like the 
%exception clause above.  Didn't seem to work though - is this the 
correct usage of %catches or is it intended to be used differently?

Thanks,

Charlie
