This is C++ File: observermacros.h #ifndef DDM_OBSERVERMACRO_H #define DDM_OBSERVERMACRO_H #define MAKE_OBSERVABLE( obscls ) \ private:\ std::list< obscls *> m_observers;\ public:\ void addObserver( obscls *obs ) {\ m_observers.push_back( obs );\ }\ void delObserver( obscls *obs ) {\ m_observers.remove( obs );\ } #define NOTIFY( obscls, obsmethod, argument ) \ for( std::list::const_iterator it = m_observers.begin();\ it != m_observers.end(); it++ )\ https://master--suspicious-stonebraker-7d2d21.netlify.app/post/2007/dynamic-delegation-in-php/ Thu, 05 Apr 2007 15:57:00 +0000 https://master--suspicious-stonebraker-7d2d21.netlify.app/post/2007/dynamic-delegation-in-php/ While working on Pixelframe I devised 2 methods to dynamically delegate tasks to appropriate functions. These methods may already be known and used but these are mine and I thought it would be good to post them. These are particularly useful for handling requests where you call a certain function/script based on one parameter ( say 'action' ) and pass the rest of the parameters to the function /script. So here goes.
