> 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.
