Packages that use Option

Package	Description
org.organicdesign.fp.collections	Type-safe versions of immutable collections (mostly from Clojure), plus unmodifiable and immutable collection interfaces that fit these collections into the java.util interfaces.
org.organicdesign.fp.oneOf	This package contains Option which has Some() and None() which is useful for indicating "Not-Found" or "End-of-stream/file".
org.organicdesign.fp.xform	Immutable descriptions of data transformations (Transformable), and a highly efficient single-pass, short-circuiting implementation that carries out those transforms in a single pass (Xform).

Uses of Option in org.organicdesign.fp.collections

Methods in org.organicdesign.fp.collections that return Option

Modifier and Type	Method and Description
Option<UnmodMap.UnEntry<K,V>>	ImSortedMap.entry(K key)
Option<UnmodMap.UnEntry<K,V>>	PersistentTreeMap.entry(K key) Returns an Option of the key/value pair matching the given key, or Option.none() if the key is not found.
Option<UnmodMap.UnEntry<K,V>>	PersistentHashMap.entry(K key)
Option<UnmodMap.UnEntry<K,V>>	PersistentHashMap.MutableHashMap.entry(K key)
Option<UnmodMap.UnEntry<K,V>>	BaseMap.entry(K key) Returns an option of the key/value pair associated with this key
default Option<T>	UnmodIterable.head() The first item in this iterable.
Option<UnmodMap.UnEntry<K,V>>	PersistentTreeMap.head() The first item in this iterable.
Option<E>	PersistentTreeSet.head() The first item in this iterable.
default Option<E>	BaseList.head() The first item in this iterable.

Uses of Option in org.organicdesign.fp.oneOf

Classes in org.organicdesign.fp.oneOf that implement Option

Modifier and Type	Class and Description
class	None<T> Represents the absence of a value
static class	Option.Some<T> Represents the presence of a value, even if that value is null.

Methods in org.organicdesign.fp.oneOf 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.
static <T> Option<T>	Option.of(T t) Deprecated.
static <T> Option<T>	Option.some(T t) Public static factory method for constructing the Some Option.
static <T> Option<T>	Option.someOrNullNoneOf(T t) Construct an option, but if t is null, make it None instead of Some.
<U> Option<U>	Option.then(Fn1<T,Option<U>> f) If this is Some, Apply the given function, else return None.
<U> Option<U>	Option.Some.then(Fn1<T,Option<U>> f) If this is Some, Apply the given function, else return None.
<U> Option<U>	None.then(Fn1<T,Option<U>> f) If this is Some, Apply the given function, else return None.
