org.organicdesign.fp.function.Fn2

Packages that use Fn2

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.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 Fn2 in org.organicdesign.fp.collections

Methods in org.organicdesign.fp.collections with parameters of type Fn2

Modifier and Type	Method and Description
default <B> B	UnmodIterable.fold(B ident, Fn2<? super B,? super T,B> reducer) Apply the function to each item, accumulating the result in u.
default <G,B> Or<G,B>	UnmodIterable.foldUntil(G accum, Fn2<? super G,? super T,B> terminator, Fn2<? super G,? super T,G> reducer) Normally you want to terminate by doing a take(), drop(), or takeWhile() before you get to the fold, but if you need to terminate based on the complete result so far, you can provide your own termination condition to this version of fold().
default <G,B> Or<G,B>	UnmodIterable.foldUntil(G accum, Fn2<? super G,? super T,B> terminator, Fn2<? super G,? super T,G> reducer) Normally you want to terminate by doing a take(), drop(), or takeWhile() before you get to the fold, but if you need to terminate based on the complete result so far, you can provide your own termination condition to this version of fold().
static <T> void	UnmodList.permutations(List<T> items, Fn2<? super T,? super T,?> f) Apply the given function against all unique pairings of items in the list.

Classes in org.organicdesign.fp.function that implement Fn2

Modifier and Type	Class and Description
static class	Fn2.Singletons

Methods in org.organicdesign.fp.function that return Fn2

Modifier and Type	Method and Description
static <A1,B1> Fn2<A1,? super B1,A1>	Fn2.first() Returns a static function that always returns the first argument it is given.
static <A,B,Z> Fn2<A,B,Z>	Fn2.memoize(Fn2<A,B,Z> f) Use only on pure functions with no side effects.
static <A1,B1> Fn2<A1,? super B1,B1>	Fn2.second() Returns a static function that always returns the second argument it is given.

Methods in org.organicdesign.fp.function with parameters of type Fn2

Modifier and Type	Method and Description
static <A,B,Z> Fn2<A,B,Z>	Fn2.memoize(Fn2<A,B,Z> f) Use only on pure functions with no side effects.

Uses of Fn2 in org.organicdesign.fp.xform

Methods in org.organicdesign.fp.xform with parameters of type Fn2

Modifier and Type	Method and Description
<B> B	Xform.fold(B ident, Fn2<? super B,? super A,B> reducer) Provides a way to collect the results of the transformation.
<U> U	Transformable.fold(U accum, Fn2<? super U,? super T,U> reducer) Apply the function to each item, accumulating the result in u.
<G,B> Or<G,B>	Xform.foldUntil(G accum, Fn2<? super G,? super A,B> terminator, Fn2<? super G,? super A,G> reducer) Thit implementation should be correct, but could be slow in the case where previous operations are slow and the terminateWhen operation is fast and terminates early.
<G,B> Or<G,B>	Xform.foldUntil(G accum, Fn2<? super G,? super A,B> terminator, Fn2<? super G,? super A,G> reducer) Thit implementation should be correct, but could be slow in the case where previous operations are slow and the terminateWhen operation is fast and terminates early.
<G,B> Or<G,B>	Transformable.foldUntil(G accum, Fn2<? super G,? super T,B> terminator, Fn2<? super G,? super T,G> reducer) Normally you want to terminate by doing a take(), drop(), or takeWhile() before you get to the fold, but if you need to terminate based on the complete result so far, you can provide your own termination condition to this version of fold().
<G,B> Or<G,B>	Transformable.foldUntil(G accum, Fn2<? super G,? super T,B> terminator, Fn2<? super G,? super T,G> reducer) Normally you want to terminate by doing a take(), drop(), or takeWhile() before you get to the fold, but if you need to terminate based on the complete result so far, you can provide your own termination condition to this version of fold().
