[C++] DictionaryBuilder provides information to determine array builder type at run-time

Open asfimport opened this issue 6 years ago • 1 comments

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())
