Detailed Description

template<class P1, class RT>
class ossimCallback1wRet< P1, RT >

Usage example, note template params can be anything:

Caller interface to register callback:

void registerCallback(ossimCallback1wRet<const ossimFilename&, bool>* cb);

Callee creation of call back mechanism:

class ProcessFileCB: public ossimCallback1wRet<const ossimFilename&, bool>
{
public:
   ProcessFileCB(
      ossimImageElevationDatabase* obj,
      bool (ossimImageElevationDatabase::*func)(const ossimFilename&))
      :
      m_obj(obj),
      m_func(func)
   {}
      
   virtual bool operator()(const ossimFilename& file) const
   {
      return ( m_obj->*m_func)(file);
   }

private:
   ossimImageElevationDatabase* m_obj;
   bool (ossimImageElevationDatabase::*m_func)(const ossimFilename& file);
};

Making/registering a callback.

ossimFileWalker* fw = new ossimFileWalker();

ossimCallback1wRet<const ossimFilename&, bool>* cb =
   new ProcessFileCB(this, &ossimImageElevationDatabase::processFile);

fw->registerProcessFileCallback(cb);
