Uses of Reducer in org.microbean.bean

Classes in org.microbean.bean that implement Reducer

Modifier and Type	Class	Description
final class	RankedReducer<C,T extends Ranked>	A Reducer implementation that works with Ranked objects.

Methods in org.microbean.bean that return Reducer

Modifier and Type	Method	Description
static final <C, T extends Ranked> Reducer<C,T>	RankedReducer.of()	Returns a RankedReducer implementation.
static <C, T> Reducer<C,T>	Reducer.ofFailing()	Returns a Reducer whose reduce(List, Object, BiFunction) method, for a given List of elements, returns the result of invoking its supplied failure handler.
static <C, T> Reducer<C,T>	Reducer.ofSimple()	Returns a Reducer whose reduce(List, Object, BiFunction) method, for a given List of elements, returns the List's sole element if the List has exactly one element, returns null if the List is empty, and returns the result of invoking its supplied failure handler otherwise.

Methods in org.microbean.bean with parameters of type Reducer

Modifier and Type	Method	Description
static <C, E> Reducible<C,E>	Reducible.of(Selectable<C,E> selectable, Reducer<C,E> r)	Calls the Reducible.of(Selectable, Reducer, BiFunction) method with the supplied selectable, the supplied r, and a reference to the fail(List, Object) method, and returns the result.
static <C, E> Reducible<C,E>	Reducible.of(Selectable<C,E> selectable, Reducer<C,E> r, BiFunction<? super List<? extends E>,? super C,? extends E> failureHandler)	Returns a Reducible implementation that uses the supplied Reducer for its reduction operations.
static <C, E> Reducible<C,E>	Reducible.ofCaching(Selectable<C,E> selectable, Reducer<C,E> r)	Calls the Reducible.ofCaching(Selectable, Reducer, BiFunction) method with the supplied selectable, the supplied r, the supplied failureHandler, and a reference to the fail(List, Object) method, and returns its result.
static <C, E> Reducible<C,E>	Reducible.ofCaching(Selectable<C,E> selectable, Reducer<C,E> r, BiFunction<? super List<? extends E>,? super C,? extends E> fh)	Calls the Reducible.ofCaching(Selectable, Reducer, BiFunction, BiFunction) method with the supplied selectable, the supplied r, the supplied fh, and a reference to the computeIfAbsent(Object, Function) method of a new ConcurrentHashMap, and returns its result.
static <C, E> Reducible<C,E>	Reducible.ofCaching(Selectable<C,E> selectable, Reducer<C,E> r, BiFunction<? super List<? extends E>,? super C,? extends E> fh, BiFunction<? super C,Function<C,E>,? extends E> cache)	Returns a Reducible implementation that uses the supplied Reducer for its reduction operations and the supplied computeIfAbsent BiFunction for its caching implementation.
