Uses of Predicate in java8.util

Methods in java8.util with parameters of type Predicate

Modifier and Type	Method and Description
Optional<T>	Optional.filter(Predicate<? super T> predicate) If a value is present, and the value matches the given predicate, returns an Optional describing the value, otherwise returns an empty Optional.

Uses of Predicate in java8.util.function

Methods in java8.util.function that return Predicate

Modifier and Type	Method and Description
static <T> Predicate<T>	Predicates.and(Predicate<? super T> this_, Predicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical AND of the this_ predicate and another.

static <T> Predicate<T>	Predicates.or(Predicate<? super T> this_, Predicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical OR of the this_ predicate and another.

Uses of Predicate in java8.util.stream

Methods in java8.util.stream with parameters of type Predicate

Modifier and Type	Method and Description
boolean	Stream.allMatch(Predicate<? super T> predicate) Returns whether all elements of this stream match the provided predicate.
boolean	Stream.anyMatch(Predicate<? super T> predicate) Returns whether any elements of this stream match the provided predicate.
Stream<T>	Stream.dropWhile(Predicate<? super T> predicate) Returns, if this stream is ordered, a stream consisting of the remaining elements of this stream after dropping the longest prefix of elements that match the given predicate.
static <T> Stream<T>	RefStreams.dropWhile(Stream<? extends T> stream, Predicate<? super T> predicate) Returns, if the passed stream is ordered, a stream consisting of the remaining elements of the passed stream after dropping the longest prefix of elements that match the given predicate.
Stream<T>	Stream.filter(Predicate<? super T> predicate) Returns a stream consisting of the elements of this stream that match the given predicate.
boolean	Stream.noneMatch(Predicate<? super T> predicate) Returns whether no elements of this stream match the provided predicate.
static <T> Collector<T,?,Map<Boolean,List<T>>>	Collectors.partitioningBy(Predicate<? super T> predicate) Returns a Collector which partitions the input elements according to a Predicate, and organizes them into a Map<Boolean, List<T>>.
static <T,D,A> Collector<T,?,Map<Boolean,D>>	Collectors.partitioningBy(Predicate<? super T> predicate, Collector<? super T,A,D> downstream) Returns a Collector which partitions the input elements according to a Predicate, reduces the values in each partition according to another Collector, and organizes them into a Map<Boolean, D> whose values are the result of the downstream reduction.
Stream<T>	Stream.takeWhile(Predicate<? super T> predicate) Returns, if this stream is ordered, a stream consisting of the longest prefix of elements taken from this stream that match the given predicate.
static <T> Stream<T>	RefStreams.takeWhile(Stream<? extends T> stream, Predicate<? super T> predicate) Returns, if the passed stream is ordered, a stream consisting of the longest prefix of elements taken from the passed stream that match the given predicate.
