tlp::ObserverHolder Class Reference

#include <Observable.h>

Detailed Description

The ObserverHolder class is a convenience class to automatically hold and unhold observers. It performs a call to Observable::holdObservers() at its creation and a call to Observable::unholdObservers() 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::unholdObservers() for each of them.

void myFunc(){
 ObserverHolder holder;//Automatically call Observable::holdObservers()

 if(someTest()){
     someOperation1();
     return;//No need to call Observable::unholdObservers() it will be called with the
destruction of the locker object
 }

}
