#include <Observable.h>
The ObserverHolder class is a convenience class to automatically hold and unhold observers. It performs a call to Observable::holdObserver() at its creation and a call to Observable::unholdObserver() at its destruction. You can use it if you have to hold observers in a function with multiple return points to avoid to call Observable::unholdObserver() for each of them.
void myFunc(){ ObserverHolder holder;//Automatically call Observable::holdObserver() if(someTest()){ someOperation1(); return;//No need to call Observable::unholdObserver() it will be called with the destruction of the locker object } }
