static SharedPtr< T > Tp::SharedPtr< T >::dynamicCast ( const SharedPtr< X > &  src  )  [inline, static]

Casts the pointer given by src to a pointer pointing to an object of type T. The cast will succeed if the C++ runtime type identification mechanism considers the type T to be the actual runtime type of the object pointed to by src or one of its (possibly indirect) parent classes. Otherwise, a null pointer is returned.

Note that this also allows down-casting a baseclass pointer to a subclass pointer.

This cast method should not be used for QObject-derived classes, as Qt provides a more portable and efficient type identification mechanism, which is used by qObjectCast().

This cast method requires the C++ dynamic runtime type identification facility to be enabled (which might be disabled by eg. the -fno-rtti flag of the GNU G++ compiler).

template<class X >
static SharedPtr< T > Tp::SharedPtr< T >::qObjectCast ( const SharedPtr< X > &  src  )  [inline, static]

Casts the pointer given by src to a pointer pointing to an object of type T. The cast will succeed if the Qt runtime type identification mechanism considers the type T to be the actual runtime type of the object pointed to by src or one of its (possibly indirect) parent classes. Otherwise, a null pointer is returned.

Note that this also allows down-casting a baseclass pointer to a subclass pointer.

This cast method MUST not be used for classes not derived from QObject. However, dynamicCast() provides the same semantics for all classes, provided the C++ runtime type identification facility is enabled. This method, on the other hand, doesn't require the standard C++ facility and is probably also faster for the types it can be used with.
