template<class T> class QuantLib::Handle< T >Shared handle to an observable.
All copies of an instance of this class refer to the same observable by means of a relinkable smart pointer. When such pointer is relinked to another observable, the change will be propagated to all the copies.
- Class T must inherit from Observable
Constructor & Destructor Documentation
Handle (const boost::shared_ptr< T > & h = boost::shared_ptr<T>(), bool registerAsObserver = true) [explicit]
- registerAsObserver is left as a backdoor in case the programmer cannot guarantee that the object pointed to will remain alive for the whole lifetime of the handle---namely, it should be set to false when the passed shared pointer does not own the pointee (this should only happen in a controlled environment, so that the programmer is aware of it). Failure to do so can very likely result in a program crash. If the programmer does want the handle to register as observer of such a shared pointer, it is his responsibility to ensure that the handle gets destroyed before the pointed object does.
