[jira] [Created] (FLINK-3978) Add contains methods to RuntimeContext

Greg Hogan created FLINK-3978:
---------------------------------

             Summary: Add contains methods to RuntimeContext
                 Key: FLINK-3978
                 URL: https://issues.apache.org/jira/browse/FLINK-3978
             Project: Flink
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.1.0
            Reporter: Greg Hogan
            Assignee: Greg Hogan
            Priority: Minor


The javadocs for `RuntimeContext` state that `getAccumulator` "throws an exception if the accumulator does not exist or if the accumulator exists, but with different type", although `AbstractRuntimeUDFContext` does not throw an exception but will return null.

The javadocs for `getBroadcastVariable` do not mention throwing an exception. Currently the only way to handle a broadcast variable that that may or may not exist is to catch and ignore the exception. Adding a  `containsBroadcastVariable` method to `RuntimeContext` would make this explicit. Likewise, `containsAccumulator`.
