Implementation of ‘??’ operator translation for non-nullable types. Overload for case if RT2 is convertable to RT1.
template<typename RT1,typename RT2,typename F> static std::conditional<std::is_convertible<RT2, RT1>::value, RT1, RT2>::type System::ObjectExt::CoalesceInternal(RT1 value, F func)
| Parameter | Description |
|---|---|
| T0 | LHS value type. |
| T1 | Type of lambda encapsulating RHS expression. |
| Parameter | Type | Description |
