Class Documentation
-
template<typename FunctionObject, typename Result = void>
class NullaryFunctionReference : public ecl::NullaryFunction<void> Creates a nullary function from a reference wrapper.
Takes a reference wrapper containing a nullary function (strictly by definition) object reference and creates a NullaryFunction descendant. This is useful in utilising the inheritance from NullaryFunction (needed for slots and similar classes).

- Template Parameters:
FunctionObject – : type of the function object to be referenced.
Result – : the return type of the nullary function.
