java.util.function.Predicate

Packages that use Predicate

Package	Description
java.util	Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
java.util.concurrent	Utility classes commonly useful in concurrent programming.
java.util.function	Functional interfaces provide target types for lambda expressions and method references.
java.util.regex	Classes for matching character sequences against patterns specified by regular expressions.
java.util.stream	Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.

Uses of Predicate in java.util

Methods in java.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, return an Optional describing the value, otherwise return an empty Optional.
default boolean	Collection.removeIf(Predicate<? super E> filter) Removes all of the elements of this collection that satisfy the given predicate.
boolean	ArrayList.removeIf(Predicate<? super E> filter)

Uses of Predicate in java.util.function

Methods in java.util.function that return Predicate

Modifier and Type	Method and Description
default Predicate<T>	Predicate.and(Predicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
static <T> Predicate<T>	Predicate.isEqual(Object targetRef) Returns a predicate that tests if two arguments are equal according to Objects.equals(Object, Object).
default Predicate<T>	Predicate.negate() Returns a predicate that represents the logical negation of this predicate.
default Predicate<T>	Predicate.or(Predicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.

Methods in java.util.function with parameters of type Predicate

Modifier and Type	Method and Description
default Predicate<T>	Predicate.and(Predicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
default Predicate<T>	Predicate.or(Predicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.

Uses of Predicate in java.util.regex

Methods in java.util.regex that return Predicate

Modifier and Type	Method and Description
Predicate<String>	Pattern.asPredicate() Creates a predicate which can be used to match a string.

Uses of Predicate in java.util.stream

Methods in java.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.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.
