How I can detect new object creation

[Ruslan Magzyumov]

I have class, for example "ClassA". It have 2 parametrs in constructor. 

open class CalssA(

    val string: String? = null,
    val value: Integer? = null
) {

    .....

}

How it possible to detect creating new object then val string is null?

val first = ClassA(value = 1)  -> detected

val second = ClassA(string = "str", value = 1) -> not detected

You'll want to visit all constructor calls (override getApplicableConstructorTypes() and visitConstructor(...) in your detector), and then inspect the constructor call's valueArguments. Then you could for example just make sure valueArguments.size == 2 and that each one is not a ULiteralExpression null.
