[jira] [Created] (BEAM-1918) a BasicDoFn with abstract methods

Xu Mingmin created BEAM-1918:
--------------------------------

             Summary: a BasicDoFn with abstract methods
                 Key: BEAM-1918
                 URL: https://issues.apache.org/jira/browse/BEAM-1918
             Project: Beam
          Issue Type: Wish
          Components: sdk-java-core
            Reporter: Xu Mingmin
            Assignee: Davor Bonaci


{{DoFn}} use annotations to define the methods, which is not quite straight-forward. A {{BasicDoFn}} with default methods, or define as abstract, can benefit developers:
1. direct view of method descriptor;
2. avoid incorrect methods during run-time;
