template<typename TReturn, typename... TArgs>

template<typename TAlternative, typename... TCallArgs>

ETL_CONSTEXPR14 TReturn etl::delegate< TReturn(TArgs...)>::call_or ( TAlternative && alternative, TCallArgs &&... args ) const

inline

Execute the delegate if valid or call alternative. Run time alternative.
