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).
FunctionObject | : type of the function object to be referenced. |
Result | : the return type of the nullary function. |
