BryanCutler commented on issue #972: ARROW-1361: [Java] Adding methods to get
type param values in NullableValueVector
URL: https://github.com/apache/arrow/pull/972#issuecomment-362665086
Yeah I've been meaning to look into this. It seems like not so much a
requirement for me any more but I can still do it if you think it's a
useful addition?

> [Java] Add minor type param accessors to NullableValueVectors

> A {{NullableValueVector}} creates private copies of each param in the minor
> type, but does not have any way public api to access them. So if given a
> {{NullableValueVector}} you would have to use the {{Field}} and cast to the
> correct type. For example, with a {{NullableTimeStampMicroTZVector}} and
> trying to get the timezone:
> {noformat}
> if field.getType.isInstanceOf[ArrowType.Timestamp] &&
> field.getType.asInstanceOf[ArrowType.Timestamp].getTimezone
> {noformat}
> It would be more convenient to have direct accessors for these type params.
> Also, it is possible to do some minor refactoring because
> {{NullableValueVectors}} does not use these type params, so there is no need
> to store them. They already exist in the inner vector object and the Field
> type.
