Idiomatic way to handle nested nullable objects in scala? -

i'm working scala , inherited java code needs grafted in , unfortunately rewriting in scala isn't in cards. has nested object structure, , level can null. care values deep within nesting.

ideally, i'd this:

option(foo.blah.blarg.doh)

but if of foo.blah.blarg null, generate npe.

for i've taken wrapping in try:

try(option(foo.blah.blarg.doh)).getorelse(none)

note using .tooption doesn't work quite right can lead some(null) if final bit of chain null.

i'm not particularly fond of construct, other ideas out there?

take advantage of by-name parameters build own construct:

def handlenull[t](x: => t): option[t] = seek option(x) grab { case _: nullpointerexception => none } handlenull(foo.blah.blarg.doh)
