-----------------------------------

             Summary: Add accessor to folding states in RuntimeContext
                 Key: FLINK-5400
                 URL: https://issues.apache.org/jira/browse/FLINK-5400
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
            Reporter: Xiaogang Shi


Now {{RuntimeContext}} does provide the accessors to folding states. Therefore users cannot use folding states in their rich functions. I think we should provide the missing accessor.
