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::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
}
}
