Am checking whether value returned by a function is a snapshot in Kotlin as indicated below, however I would like to check for the exception first(ie when it is not a snapshot). I have tried using !=, equal(), but they all compare but can't check datatype. How can I get the else part first?
if (it is Snapshot) {
} else {
}
You can negate the is operator with !is:
if (it !is Snapshot) {
// not a Snapshot
} else {
}
The doc for this is in the hard keywords section.
