-----------------------------------
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.
