             Summary: [Java] Add minor type param accessors to NullableValueVectors
                 Key: ARROW-1361
                 URL: https://issues.apache.org/jira/browse/ARROW-1361
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java - Vectors
            Reporter: Bryan Cutler
            Assignee: Bryan Cutler


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.
