ELVIS operator

[jjude]

How can i change these ELVIS operator?

val tag = intent.getParcelableExtra<Tag>(NfcAdapter.EXTRA_TAG)
if (tag == null) return

val ndef = Ndef.get(tag)
if(ndef == null) return

val raws = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES)
if(raws == null) return

Elvis has left the building?

Elvis is in fact alive and well. Here's the code equivalent

val l = b?.length ?: -1

Notice the Elvis quiff?

Although in answer to the OP, the Elvis operator isn't really applicable to your code, as all you're doing is checking for null. Besides, Kotlin has a handy automatic null safety check operator.

Android Studio encourages me to move if to Elvis method
but i don't need to care about it
