[gdal-dev] Using SWIG from a Driver

[Stefano Moratto]

Hi,

     I think it is possibile using the swig's director feature: Calling
back non c/c++ from c/c++  code.

Basically you have to develop your driver as a C++ class declared in a swig
interface file (.i) declaring virtual functions that have to implements the
features of your driver. This driver should be viewed as an abstract driver.
The "concrete" driver is implemented by a swig generated class that calls
you java code implementing the virtual functions you declared in you ".i
file".

Regards,
Stefano
