[jira] [Comment Edited] (ARROW-13663) [C++] RecordBatchReader should support STL-like iteration

--------------------------------------------------------------

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?

> Our custom {{Iterator<T>}} has support for STL-like iteration (allowing natural for loops), but {{RecordBatchReader}} doesn't. Adding STL-like iteration would be a significant quality of life improvement for developers
