             Summary: Correct comments in ListState class
                 Key: FLINK-13057
                 URL: https://issues.apache.org/jira/browse/FLINK-13057
             Project: Flink
          Issue Type: Bug
          Components: Runtime / State Backends
            Reporter: Hequn Cheng
            Assignee: Hequn Cheng


ListState can be a keyed state or an operator state, but the comment in ListState said it can only be a keyed state：
{code:java}
The state is only accessible by functions applied on a {@code KeyedStream}. 
{code}
We can change the comment from
{code:java}
* <p>The state is only accessible by functions applied on a {@code KeyedStream}. The key is
* automatically supplied by the system, so the function always sees the value mapped to the
* key of the current element. That way, the system can handle stream and state partitioning
* consistently together.{code}
to

Appreciate any suggestions.
