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

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

inline explicit UnaryFunctionReference(const ReferenceWrapper<FunctionObject> &wrapper)
