How to access data in the RecordBatch (c++)?

["Arkadiy Vertleyb (BLOOMBERG/ 120 PARK)" <av...@bloomberg.net>]

Hi, 

All I was able to figure out so far was - column() returns Array and then GetScalar() returns Scalar.  Which can be converted to a string.  

Is this the right way?  Anything else can be done to a Scalar?  Can I get the binary data?  Or converted to a type of my choice?

Thanks,
Arkadiy

HI Arkadiy,
It really depends on what you want to do with the data.  Subclasses of
Array have accessors for primitive objects as well (e.g. BaseBinary for
Utf/binary data [1]) can access string_view objects
