org.organicdesign.fp.xform.Transformable

Packages that use Transformable

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.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 Transformable in org.organicdesign.fp.collections

Subinterfaces of Transformable in org.organicdesign.fp.collections

Modifier and Type	Interface and Description
interface	BaseList<E> Adds copy-on-write, "fluent interface" methods to UnmodList.
interface	BaseMap<K,V> Adds copy-on-write, "fluent interface" methods to UnmodMap.
interface	BaseSet<E> Adds copy-on-write, "fluent interface" methods to UnmodSet.
interface	BaseUnsortedMap<K,V> Adds BaseUnsortedMap.equator() to BaseMap which is an unsorted-only operation.
interface	ImList<E> Immutable copy-on-write list
interface	ImMap<K,V> An immutable map with no guarantees about its ordering.
interface	ImSet<E> An immutable set with no guarantees about its ordering
interface	ImSortedMap<K,V> An immutable sorted map.
interface	ImSortedSet<E> An immutable sorted set interface
interface	MutableList<E> A mutate-in-place interface using the same copy-on-write methods as BaseList and ImList so that you can treat mutable and immutable lists the same.
interface	MutableUnsortedMap<K,V> Interface for mutable (hash) map builder.
interface	MutableUnsortedSet<E> Interface for mutable (hash) set builder.
interface	UnmodCollection<E> Don't implement this interface directly if you don't have to.
interface	UnmodIterable<T> An unmodifiable Iterable, without any guarantee about order.
interface	UnmodList<E> Formalizes the return type of Collections.unmodifiableList(List), deprecating mutator methods and implementing them to throw exceptions.
interface	UnmodMap<K,V> An unmodifiable map.
interface	UnmodSet<E> An unmodifiable set
interface	UnmodSortedCollection<E>
interface	UnmodSortedIterable<T> An unmodifiable Iterable, with guaranteed order.
interface	UnmodSortedMap<K,V> An unmodifiable SortedMap.
interface	UnmodSortedSet<E> An unmodifiable SortedSet.

Classes in org.organicdesign.fp.collections that implement Transformable

Modifier and Type	Class and Description
class	PersistentHashMap<K,V> Rich Hickey's immutable rendition of Phil Bagwell's Hash Array Mapped Trie.
static class	PersistentHashMap.MutableHashMap<K,V>
class	PersistentHashSet<E> A wrapper that turns a PersistentTreeMap into a set.
static class	PersistentHashSet.MutableHashSet<E>
class	PersistentTreeMap<K,V> Persistent Red Black Tree.
class	PersistentTreeSet<E> A wrapper that turns a PersistentTreeMap into a set.
class	PersistentVector<E> This started out as Rich Hickey's PersistentVector class from Clojure in late 2014.
static class	PersistentVector.MutableVector<F>
class	RangeOfInt An efficient (in both time and memory) implementation of List.
class	RrbTree<E> This is based on the paper, "RRB-Trees: Efficient Immutable Vectors" by Phil Bagwell and Tiark Rompf, with the following differences:
static class	RrbTree.ImRrbt<E> Immutable version of an RrbTree
static class	RrbTree.MutableRrbt<E> Mutable version of an RrbTree
static class	UnmodIterable.AbstractUnmodIterable<T> Implements equals and hashCode() methods compatible with all java.util collections (this algorithm is not order-dependent) and toString which takes the name of the sub-class.
static class	UnmodList.AbstractUnmodList<E> Implements equals and hashCode() methods compatible with java.util.List (which ignores order) to make defining unmod lists easier.
static class	UnmodMap.AbstractUnmodMap<K,V> Implements equals and hashCode() methods compatible with java.util.Map (which ignores order) to make defining unmod Maps easier.
static class	UnmodSet.AbstractUnmodSet<T> Implements equals and hashCode() methods compatible with java.util.Set (which ignores order) to make defining unmod sets easier, especially for implementing Map.keySet() and such.

Uses of Transformable in org.organicdesign.fp.xform

Classes in org.organicdesign.fp.xform that implement Transformable

Modifier and Type	Class and Description
class	Xform<A> An immutable description of operations to be performed (a transformation, transform, or x-form).

Methods in org.organicdesign.fp.xform that return Transformable

Modifier and Type	Method and Description
Transformable<T>	Transformable.concat(Iterable<? extends T> list) Add items to the end of this Transformable (precat() adds to the beginning)
Transformable<T>	Transformable.drop(long numItems) Ignore the first n items and return only those that come after.
Transformable<T>	Transformable.filter(Fn1<? super T,Boolean> predicate) Return only the items for which the given predicate returns true.
<U> Transformable<U>	Transformable.flatMap(Fn1<? super T,Iterable<U>> f) Transform each item into zero or more new items using the given function.
<U> Transformable<U>	Transformable.map(Fn1<? super T,? extends U> func) Transform each item into exactly one new item using the given function.
Transformable<T>	Transformable.precat(Iterable<? extends T> list) Add items to the beginning of this Transformable ("precat" is a PREpending version of conCAT).
Transformable<T>	Transformable.take(long numItems) Return only the first n items.
Transformable<T>	Transformable.takeWhile(Fn1<? super T,Boolean> predicate) Return items from the beginning until the given predicate returns false.
