> Key: FLINK-13820
> URL: https://issues.apache.org/jira/browse/FLINK-13820
> Project: Flink
> Issue Type: Sub-task

> Breaking the line of too long statements (line longness is yet to be fully
> defined) to improve code readability in case of
> * Long function argument lists (declaration or call): void func(type1 arg1,
> type2 arg2, ...)
> * Long sequence of chained calls:
> list.stream().map(...).reduce(...).collect(...)...
> Rules:
> * Break the list of arguments/calls if the line exceeds limit or earlier if
> you believe that the breaking would improve the code readability
> * If you break the line then each argument/call should have a separate line,
> including the first one
> * Each new line argument/call should have one extra indentation relative to
> the line of the parent function name or called entity
> * The opening parenthesis always stays on the line of the parent function
> name
> * The possible thrown exception list is never broken and stays on the same
> last line
> * The dot of a chained call is always on the line of that chained call
> proceeding the call at the beginning
> Examples of breaking:
> * Function arguments
> {code:java}
> public void func(
> int arg1,
> int arg2,
> ...) throws E1, E2, E3 {
>
> }{code}
> * Chained method calls:
> {code:java}
> values
> .stream()
> .map(...)
> .collect(...);{code}
