Hi Can someone please explain me this code ?

fun aFun() : ObjectA?{
val (side,line) = when(someData){
      is TypeA -> thread.position?.let { diffData.linesMapper.findFileLocation(it) } ?: return null
      is TypeB -> ... ?: return null
}

return ObjectA(side,line)

when ObjectA constructor is expecting null safe type of side and line. in case of is TypeA happen and it return null what will be the values in side and line ? tnx

the

return null

lines return from the entire method, not just the

when

expression

tnx!!!
