ASF GitHub Bot updated ARROW-6558: ---------------------------------- Labels: pull-request-available (was: ) > [C++] Refactor Iterator to a type erased handle > ----------------------------------------------- > > Key: ARROW-6558 > URL: https://issues.apache.org/jira/browse/ARROW-6558 > Project: Apache Arrow > Issue Type: Improvement > Components: C++ > Reporter: Benjamin Kietzman > Assignee: Benjamin Kietzman > Priority: Major > Labels: pull-request-available > > Since {{Iterator<T>}} is used as a base class for exported classes and is > instantiated in both arrow.dll and arrow_dataset.dll we get multiple > definition errors. The solution taken by MSVC's stl implementation in the > similar case of {{std::function}} is type erasure. Since it's not a base > class MSVC doesn't force public visibility of its members. -- This message was sent by Atlassian Jira (v8.3.2#803003)
