[jira] [Created] (ARROW-6288) [Java] Implement TypeEqualsVisitor comparing vector type equals considering names and metadata

Ji Liu created ARROW-6288:
-----------------------------

             Summary: [Java] Implement TypeEqualsVisitor comparing vector type equals considering names and metadata
                 Key: ARROW-6288
                 URL: https://issues.apache.org/jira/browse/ARROW-6288
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Java
            Reporter: Ji Liu
            Assignee: Ji Liu


Currently when we compare range/vector equals, we first compare vector {{Field}} by its equals method, in this case, it’s hard to specify whether compare names or metadata.

Implement a {{TypeEqualsVisitor}} will make type comparisons more flexible like cpp implementation dose [https://github.com/apache/arrow/blob/master/cpp/src/arrow/compare.cc#L712]
