Kouhei Sutou created ARROW-5355: ----------------------------------- Summary: [C++] DictionaryBuilder provides information to determine array builder type at run-time Key: ARROW-5355 URL: https://issues.apache.org/jira/browse/ARROW-5355 Project: Apache Arrow Issue Type: Improvement Components: C++ Reporter: Kouhei Sutou
This is needed for Arrow GLib. In Arrow GLib, we need to determine how to wrap Arrow C++ `ArrayBuilder` at run-time. `ArrayBuilder` may be passed as a generic `ArrayBuilder` instead of concrete `DictionaryBuilder`. (e.g. `RecordBatchBuilder::GetField()`) See also: https://github.com/apache/arrow/pull/4316#issuecomment-492995395 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
