org.organicdesign.fp.function.Fn1

Packages that use Fn1

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.function	Exception-friendly functional interfaces named by the number of arguments: Fn0, Fn1, Fn2....
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).
