anyone know a quick way to bind guava Optional<X> to gson?

[Adrian Cole]

Hey, guys.

There are cases where we know that some things are going to be
Nullable. Since few read annotations personally, seems ideal to just
swap out @Nullable for Optional<X> (at least in fields). Does anyone
have an idea how to write a gson type adapter for this?

Are we happy with the fact that replacing the annotation with Optional
means that code will break because the fields now have new types?

via Jesse, who probably bounced:

"It should be relatively easy to write a TypeAdapterFactory[1] that
does it. You'll need to unpack the optional and delegate to the type
adapter of the adapted value."

also inline :)

well, I'm talking about new code :)
