Packages that use Function1

Package	Description
org.organicdesign.fp	A data definition language, and other tools for writing functional Java.
org.organicdesign.fp.collections	Type-safe versions of the immutable Clojure collections, plus unmodifiable and immutable collection interfaces that extend the java.util collections, deprecating the mutate-in-place methods (Unmod____) and adding methods that return a new, immutable, modified version of the collection (Im____).
org.organicdesign.fp.either	This approximates union of two types for Java - for when something (e.g.
org.organicdesign.fp.function	Exception-friendly functional interfaces named by the number of arguments: Function0, Function1, Function2....
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).
