[C++] [Python] MakeDense and MakeSparse in UnionArray should accept a vector of Field

    XMLWordPrintableJSON

    Details

      Description

      Currently MakeDense and MakeUnion of UnionArray couldn't create a UnionArray with user-specified field names.  This is bugs of these functions.

      To fix them, optional arguments of std::vector<Field> should be added.

      GLib and Python bindings should be fixed, together.
