Detailed Description

template<class P1>
class ossimCallback1< P1 >

Usage example, note template params can be anything:

Caller interface to register callback:

void registerCallback(ossimCallback1<const ossimFilename&>* cb);

Callee creation of call back mechanism:

class ProcessFileCB: public ossimCallback1<const ossimFilename&>
{
public:
   ProcessFileCB(
      ossimImageElevationDatabase* obj,
      void (ossimImageElevationDatabase::*func)(const ossimFilename&))
      :
      m_obj(obj),
      m_func(func)
   {}
      
   virtual void operator()(const ossimFilename& file) const
   {
      ( m_obj->*m_func)(file);
   }

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

Making/registering a callback.

ossimFileWalker* fw = new ossimFileWalker();

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

fw->registerProcessFileCallback(cb);
