Method Summary

Modifier and TypeMethod and Description
public boolean
allSatisfy(Predicate<? super T> predicate)

Overrides org.eclipse.collections.impl.AbstractRichIterable.allSatisfy.

Implements org.eclipse.collections.api.RichIterable.allSatisfy.

Returns true if the predicate evaluates to true for every element of the iterable or if the iterable is empty.

public boolean
anySatisfy(Predicate<? super T> predicate)

Overrides org.eclipse.collections.impl.AbstractRichIterable.anySatisfy.

Implements org.eclipse.collections.api.RichIterable.anySatisfy.

Returns true if the predicate evaluates to true for any element of the iterable.

public T
detect(Predicate<? super T> predicate)

Overrides org.eclipse.collections.impl.AbstractRichIterable.detect.

Implements org.eclipse.collections.api.RichIterable.detect.

Returns the first element of the iterable for which the predicate evaluates to true or null in the case where no element returns true.

public Optional<T>
detectOptional(Predicate<? super T> predicate)

Overrides org.eclipse.collections.impl.AbstractRichIterable.detectOptional.

Implements org.eclipse.collections.api.RichIterable.detectOptional.

Returns the first element of the iterable for which the predicate evaluates to true as an Optional.

public LazyIterable<T>
distinct()

Overrides org.eclipse.collections.impl.lazy.AbstractLazyIterable.distinct.

Implements org.eclipse.collections.api.LazyIterable.distinct.

Creates a deferred distinct iterable to get distinct elements from the current iterable.

public void
each(Procedure<? super T> procedure)

Implements org.eclipse.collections.api.RichIterable.each.

The procedure is executed for each element in the iterable.

public void
forEachWithIndex(ObjectIntProcedure<? super T> objectIntProcedure)

Overrides org.eclipse.collections.impl.AbstractRichIterable.forEachWithIndex.

Implements org.eclipse.collections.api.InternalIterable.forEachWithIndex.

Iterates over the iterable passing each element and the current relative int index to the specified instance of ObjectIntProcedure.

public Iterator<T>
iterator()

Implements java.lang.Iterable.iterator.

Returns an iterator over elements of type T.

public boolean
noneSatisfy(Predicate<? super T> predicate)

Overrides org.eclipse.collections.impl.AbstractRichIterable.noneSatisfy.

Implements org.eclipse.collections.api.RichIterable.noneSatisfy.

Returns true if the predicate evaluates to false for every element of the iterable or if the iterable is empty.

public boolean allSatisfy(Predicate<? super T> predicate)

Overrides org.eclipse.collections.impl.AbstractRichIterable.allSatisfy.

Implements org.eclipse.collections.api.RichIterable.allSatisfy.

Doc from org.eclipse.collections.api.RichIterable.allSatisfy.

Returns true if the predicate evaluates to true for every element of the iterable or if the iterable is empty. Otherwise, returns false.

Overrides org.eclipse.collections.impl.AbstractRichIterable.anySatisfy.

Implements org.eclipse.collections.api.RichIterable.anySatisfy.

Doc from org.eclipse.collections.api.RichIterable.anySatisfy.

Returns true if the predicate evaluates to true for any element of the iterable. Returns false if the iterable is empty, or if no element returned true when evaluating the predicate.

public T detect(Predicate<? super T> predicate)

Overrides org.eclipse.collections.impl.AbstractRichIterable.detect.

Implements org.eclipse.collections.api.RichIterable.detect.

Doc from org.eclipse.collections.api.RichIterable.detect.

Returns the first element of the iterable for which the predicate evaluates to true or null in the case where no element returns true. This method is commonly called find.

Example using a Java 8 lambda expression: 

Person person =
    people.detect(person -> person.getFirstName().equals("John") && person.getLastName().equals("Smith"));

Implements org.eclipse.collections.api.RichIterable.detectOptional.

Doc from org.eclipse.collections.api.RichIterable.detectOptional.

Returns the first element of the iterable for which the predicate evaluates to true as an Optional. This method is commonly called find.

Example using a Java 8 lambda expression: 

Person person =
    people.detectOptional(person -> person.getFirstName().equals("John") && person.getLastName().equals("Smith"));

public LazyIterable<T> distinct()

Overrides org.eclipse.collections.impl.lazy.AbstractLazyIterable.distinct.

public void each(Procedure<? super T> procedure)

Implements org.eclipse.collections.api.RichIterable.each.

Doc from org.eclipse.collections.api.RichIterable.each.

The procedure is executed for each element in the iterable.

Example using a Java 8 lambda expression: 

people.each(person -> LOGGER.info(person.getName()));
This method is a variant of InternalIterable#forEach(Procedure) that has a signature conflict with Iterable#forEach(java.util.function.Consumer).

public void forEachWithIndex(ObjectIntProcedure<? super T> objectIntProcedure)

Overrides org.eclipse.collections.impl.AbstractRichIterable.forEachWithIndex.

Implements org.eclipse.collections.api.InternalIterable.forEachWithIndex.

Doc from org.eclipse.collections.api.InternalIterable.forEachWithIndex.

Iterates over the iterable passing each element and the current relative int index to the specified instance of ObjectIntProcedure.

Example using a Java 8 lambda: 

people.forEachWithIndex((Person person, int index) -> LOGGER.info("Index: " + index + " person: " + person.getName()));

Example using an anonymous inner class: 

people.forEachWithIndex(new ObjectIntProcedure<Person>()
{
    public void value(Person person, int index)
    {
        LOGGER.info("Index: " + index + " person: " + person.getName());
