]SmartPtr::Cast() const method
Casts pointer to its type itself.
template<class Y,typename Check> std::enable_if_t<std::is_same<Y, T>::value, SmartPtr<Y>> System::SmartPtr<T>::Cast() const
Template parameters
| Parameter | Description |
|---|---|
| Y | Target type of pointed object. |
| Check | Flags to throw exception if no cast available. |
Return Value
Pointer of changed type which is always in shared mode.
SmartPtr::Cast() const method
Casts pointer to base type using static_cast.
template<class Y,typename Check> std::enable_if_t<!std::is_same<Y, T>::value &&std::is_base_of<Y, T>::value, SmartPtr<Y>> System::SmartPtr<T>::Cast() const
Template parameters
| Parameter | Description |
|---|---|
| Y | Target type of pointed object. |
| Check | Flags to throw exception if no cast available. |
Return Value
Pointer of changed type which is always in shared mode.
SmartPtr::Cast() const method
Casts pointer to derived type dynamic_cast.
template<class Y,typename Check> std::enable_if_t<Check::value &&!std::is_same<Y, T>::value &&!std::is_base_of<Y, T>::value, SmartPtr<Y>> System::SmartPtr<T>::Cast() const
Template parameters
| Parameter | Description |
|---|---|
| Y | Target type of pointed object. |
| Check | Flags to throw exception if no cast available. |
Return Value
Pointer of changed type which is always in shared mode. Throws InvalidCastException if no conversion available.
SmartPtr::Cast() const method
Casts pointer to derived type dynamic_cast.
template<class Y,typename Check> std::enable_if_t<!Check::value &&!std::is_same<Y, T>::value &&!std::is_base_of<Y, T>::value, SmartPtr<Y>> System::SmartPtr<T>::Cast() const
Template parameters
| Parameter | Description |
|---|---|
| Y | Target type of pointed object. |
| Check | Flags to throw exception if no cast available. |
Return Value
