The when statement should be used only to clearly define some new branches in the control flow. As soon as a case clause contains too
many statements this highly decreases the readability of the overall control flow statement. In such case, the content of the case clause should be
extracted into a dedicated function.
Noncompliant code example
With the threshold set at 5:
when (myVariable) {
0 -> {// Noncompliant: 6 lines till next case
methodCall1("");
methodCall2("");
methodCall3("");
methodCall4("");
}
1 -> {
...
}
}
Compliant solution
when (myVariable) {
0 -> doSomething()
1 -> {
...
}
}
...
fun doSomething() {
methodCall1("");
methodCall2("");
methodCall3("");
methodCall4("");
}
