Interface Summary

Interface	Description
Option<T>	Indicates presence or absence of a value (null is a valid, present value) or end-of-stream.
Or<G,B>	`Or` represents the presence of a successful outcome, or an error.

Class Summary

Class	Description
FunctionUtils	A dumping ground for utility functions that aren't useful enough to belong in StaticImports.
FunctionUtils.UnmodifiableCollection<T>	Wraps a collection.
FunctionUtils.UnmodifiableIterator<E>	Wraps an iterator.
FunctionUtils.UnmodifiableList<T>	Wraps a list.
FunctionUtils.UnmodifiableListIterator<T>	Wraps a list iterator.
FunctionUtils.UnmodifiableMap<K,V>	Wraps a map.
FunctionUtils.UnmodifiableSet<T>	Wraps a set.
FunctionUtils.UnmodifiableSortedIterator<E>	Wraps an ordered iterator.
FunctionUtils.UnmodifiableSortedMap<K,V>	Wraps a sorted map.
FunctionUtils.UnmodifiableSortedSet<T>	Wraps a sorted set.
LazyRef<T>	Lazily initialize a value (and free the initialization resources) on the first call to get().
Option.None<T>	Represents the absence of a value
Option.Some<T>	Represents the presence of a value, even if that value is null.
Or.Bad<G,B>	Represents the presence of a Bad value (and absence of a Good).
Or.Good<G,B>	Represents the presence of a Good value (and absence of a Bad).
StaticImports	A mini data definition language composed of vec(), tup(), map(), set(), plus xform() which makes java.util collections transformable.

Package org.organicdesign.fp Description

A data definition language, and other tools for writing functional Java. Also, there are experimental features you may find useful:

• An Equator and ComparisonContext which work like `java.util.Comparator`, but for hash-based collections.
• Memoization for functions
