Dhruv Vats edited comment on ARROW-13663 at 12/13/21, 5:11 PM: --------------------------------------------------------------- Because the {{RecordBatchReader}} is an abstract class, is there a straightforward way to define STL like iterators for it? I tried using {{{}shared_ptr as given in Iterator<T>{}}}, but can't use them as the class is abstract. Does something like {{shared_from_this()}} have to be used?
