wxWeakRefDynamic<T> is a template class for weak references that is used in the same way as wxWeakRef<T>.
The only difference is that wxWeakRefDynamic defaults to using dynamic_cast
for establishing the object reference (while wxWeakRef defaults to static_cast
).
So, wxWeakRef will detect a type mismatch during compile time and will have a little better run-time performance. The role of wxWeakRefDynamic is to handle objects which derived type one does not know.
dynamic_cast
as the last measure (if available from the compiler and enabled when building wxWidgets).For general cases, wxWeakRef<T> is the better choice.
For API documentation, see: wxWeakRef<T>.
T | The type to which the smart pointer points to. |
