Returns the QName of the member at the specified index. Parameters: index  the member index Returns: the QName of the member at the specified index Exceptions: ReflectException  If the index is out of bounds Implemented in IT_Reflect::UnionImpl.

virtual const Reflection* IT_Reflect::Union::get_selected_member (   )  const throw ((ReflectException)) [pure virtual]

Returns a read-only reflection object of the selected member. Returns: a read-only Reflection of the selected member. Caller must call _remove_ref(). Exceptions: ReflectException  If no member is selected
