ASF GitHub Bot updated ARROW-17480: ----------------------------------- Labels: Java pull-request-available (was: Java) > [Java] add setNull() to FieldVector interface > --------------------------------------------- > > Key: ARROW-17480 > URL: https://issues.apache.org/jira/browse/ARROW-17480 > Project: Apache Arrow > Issue Type: Improvement > Components: Java > Affects Versions: 9.0.0 > Reporter: Larry White > Assignee: Larry White > Priority: Major > Labels: Java, pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > Only three FieldVector types do not implement setNull(): UnionVector, > DenseUnionVector and NullVector, preventing it from being addable to the > ValueVector interface and thus requiring a cast when used. > For all three vector types it could be added as a no-op. For NullVector, all > values are already null. For the other two, null values are not supported at > the top level, but only in the individual child vectors. A no-op > implementation is not only consistent with the existing writeNull() > operations in the Union and DenseUnion Writer classes, but it is consistent > with isNull(), which always returns false. > An implementation is also needed in the abstract ExtensionTypeVector, which > can delegate to the underlying vector object. > See also a similar issue opened for FieldWriter (ARROW-2538), which may be > closable given the current code base. -- This message was sent by Atlassian Jira (v8.20.10#820010)
