| void Smart< ReferenceCountedObject >::decref | ( | ) | const [inline] |
The general idea is to decrease the reference count of the underlying object in an atomic manner. If the object reaches zero we delete it. With the deletion there are some tricky semantics involved. For instance, if the object that is deleted suddenly passes itself to another one then the reference count will be increased again. However, the object was just being deleted, which means that it should not be deleted again. There are two possible strategies to use this file. Either you do care about using an object that is being deleted (leave everything as it is, the program will crash when you do so). Or you don't care about it and really only want one deletion. In that case, uncomment the assert in the incref method. In both cases, we detect a deletion operation by decreffing the pointer once more.
