Summary: Breaking long function argument lists and chained method calls
Key: FLINK-13820
URL:
https://issues.apache.org/jira/browse/FLINK-13820 Project: Flink
Issue Type: Sub-task
Components: Documentation, Project Website
Reporter: Andrey Zagrebin
Assignee: Andrey Zagrebin
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}
