The switch 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 method.
Noncompliant code example
With the default threshold of 5:
switch (myVariable) {
case 0: // Noncompliant - 6 lines till next case or default case
trace("");
trace("");
trace("");
trace("");
break;
case 1:
...
}
Compliant solution
switch (myVariable) {
case 0:
printSomething()
break;
case 1:
...
}
...
private function printSomething() {
trace("");
trace("");
trace("");
trace("");
}
