Methods in org.organicdesign.fp that return Option

Modifier and Type	Method and Description
static <T> Option<T>	Option.none() Calling this instead of referring to NONE directly can make the type infrencer happy.

<U> Option<U>	Option.None.then(Function1<T,Option<U>> f) If this is Some, Apply the given function, else return None.
<U> Option<U>	Option.Some.then(Function1<T,Option<U>> f) If this is Some, Apply the given function, else return None.
