Function documentation

template<typename T, typename U>
T runtime_cast(U* u) noexcept

Casts a pointer to another type.

Safely converts pointers to classes up, down, and sideways along the inheritance hierarchy of classes annotated by DEATH_RUNTIME_OBJECT() in an optimized way. Additionally, it can perform downcast at no performance cost. It also pulls the actual pointer from std::shared_ptr and std::unique_ptr without taking ownership.

If DEATH_SUPPRESS_RUNTIME_CAST is defined, the optimized implementation is suppressed and the standard dynamic_cast<T>() is used to cast the pointer instead.
