Kotlin call function only if all arguments are not null

Question

Is there a way in kotlin to prevent function call if all (or some) arguments are null? For example Having function:

fun test(a: Int, b: Int) { /* function bo         


        

Answer 1

NO! is the answer to your question(as far as I know)

Your best bet(assuming the function is not exposed) is what you said.

a?.let { b?.let { test(a, b) } }

If the function is exposed, and might be called without these checks, then you need to put the checks inside your function.

fun test(a: Int?, b: Int?) {
    if (listOf(a, b).filterNotNull().size < 2) return

    println("Function was called")
}
