[jira] [Created] (ARROW-6250) [Java] Implement ApproxEqualsVisitor comparing approx for floating point

Ji Liu created ARROW-6250:
-----------------------------

             Summary: [Java] Implement ApproxEqualsVisitor comparing approx for floating point
                 Key: ARROW-6250
                 URL: https://issues.apache.org/jira/browse/ARROW-6250
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Java
            Reporter: Ji Liu
            Assignee: Ji Liu


Currently we already implemented {{RangeEqualsVisitor/VectorEqualsVisitor}} for comparing range/vector.

And ARROW-6211 is created to make {{ValueVector}} work with generic visitor.

We should also implement {{ApproxEqualsVisitor}} to compare floating point just like cpp does
