=== Noncompliant code example
|

|

[source,kotlin]

when(param) { // missing else
|
|
1 -> doSomething()
|
|
2 -> doSomethingElse()

=== Compliant solution
|
|
|
|
[source,kotlin]
|
|
----
|
|
when(param) {
|
|
1 -> doSomething()
|
|
2 -> doSomethingElse()
|
|
else -> error("myMessage")
|
|
}
|
|
----
|
|
|
|
=== Exceptions
|
|
|
|
If the ``++when++`` clause is used as an expression, Kotlin compiler already enforces that all possible cases are covered with branch conditions. So no issue will be raised in this case.
|
|
|
|
|
|
Example:
|
|
|
|
----
|
|
enum class Day {
|
|
SUNDAY, MONDAY
|
|
}
|
|
...
|
|
val myVal = when(day) {
|
|
MyEnum.SUNDAY -> 1
|
|
MyEnum.MONDAY -> 2
|
|
}
