Why is this an issue?
A long parameter list can indicate that a new structure should be created to wrap the numerous parameters or that the function is doing too many
things.
Noncompliant code example
With a maximum number of 4 parameters:
fun foo(p1: String, p2: String, p3: String, p4: String, p5: String) { // Noncompliant
// ...
}
Compliant solution
fun foo(p1: String, p2: String, p3: String, p4: String) {
// ...
}
Exceptions
Methods annotated with Spring’s @RequestMapping (and related shortcut annotations, like @GetRequest) or
@JsonCreator may have a lot of parameters, encapsulation being possible. Such methods are therefore ignored.
