[jira] [Created] (ARROW-5508) [C++] Create reusable Iterator interface

Wes McKinney created ARROW-5508:
-----------------------------------

             Summary: [C++] Create reusable Iterator<T> interface 
                 Key: ARROW-5508
                 URL: https://issues.apache.org/jira/browse/ARROW-5508
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney
            Assignee: Wes McKinney
             Fix For: 0.14.0


We have various iterator-like classes. I envision a reusable interface like

{code}
template <typename T>
class Iterator {
 public:
  virtual ~Iterator() = default;
  virtual Status Next(T* out) = 0;
}
{code}
