Detailed Description

template<class ValueType>
class dash::UniversalMember< ValueType >

Utility class template to capture values from both moved temporaries (rvalues) and named references to avoid temporary copies.

Usage example

// Class using dash::UniversalMember 
template <class T>
class MyClass {
  dash::UniversalMember<T> _value;
public:
  constexpr explicit MyClass(T && value)
  : _value(std::forward<T>(value))
  { }

  constexpr explicit MyClass(const T & value)
  : _value(value)
  { }

        T & value()       { return _value; }
  const T & value() const { return _value; }
};

// Value type definition and passing values to a class using
// dash::UniversalMember
template <
  class T,
  class ValueT = typename std::remove_const<
                   typename std::remove_reference<T>::type
                 >::type
>
MyClass<ValueT>
make_my_class(T && val) {
  return MyClass<ValueT>(std::forward<T>(val));
}
