--------------------------------
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;
