the trouble is very stupid: observer_ptr is intepreted by the compiler as a
class instead of
an ptr reference.
solution:
void Referenced::addObserver(Observer* in_observer_ptr)
{
if (_refMutex)
{
OpenThreads::ScopedLock<OpenThreads::Mutex>
lock(*_refMutex);
if (!_observers) _observers = new ObserverSet;
if (_observers)
static_cast<ObserverSet*>(_observers)->insert(in_observer_ptr);
}
else
{
if (!_observers) _observers = new ObserverSet;
if (_observers)
static_cast<ObserverSet*>(_observers)->insert(in_observer_ptr);
}
}
void Referenced::removeObserver(Observer* in_observer_ptr)
{
if (_refMutex)
{
OpenThreads::ScopedLock<OpenThreads::Mutex>
lock(*_refMutex);
if (_observers)
static_cast<ObserverSet*>(_observers)->erase(in_observer_ptr);
