with
public static <T> CompositeIterable<T> with(java.lang.Iterable<T>... iterables)
-
each
public void each(Procedure<? super E> procedure)
Description copied from interface:RichIterable
The procedure is executed for each element in the iterable.Example using a Java 8 lambda expression:
people.each(person -> LOGGER.info(person.getName()));
Example using an anonymous inner class:
people.each(new Procedure<Person>() { public void value(Person person) { LOGGER.info(person.getName()); } });
This method is a variant ofInternalIterable.forEach(Procedure)
that has a signature conflict withIterable.forEach(java.util.function.Consumer)
.- See Also:
InternalIterable.forEach(Procedure)
,Iterable.forEach(java.util.function.Consumer)
-
forEachWithIndex
public void forEachWithIndex(ObjectIntProcedure<? super E> objectIntProcedure)
Description copied from interface:InternalIterable
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()); } });
- Specified by:
forEachWithIndex
in interfaceInternalIterable<E>
- Overrides:
forEachWithIndex
in classAbstractRichIterable<E>
-
forEachWith
public <P> void forEachWith(Procedure2<? super E,? super P> procedure, P parameter)
Description copied from interface:InternalIterable
The procedure2 is evaluated for each element in the iterable with the specified parameter provided as the second argument.Example using a Java 8 lambda:
people.forEachWith((Person person, Person other) -> { if (person.isRelatedTo(other)) { LOGGER.info(person.getName()); } }, fred);
Example using an anonymous inner class:
people.forEachWith(new Procedure2<Person, Person>() { public void value(Person person, Person other) { if (person.isRelatedTo(other)) { LOGGER.info(person.getName()); } } }, fred);

-
anySatisfy
public boolean anySatisfy(Predicate<? super E> predicate)
Description copied from interface:RichIterable
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.- Specified by:
anySatisfy
in interfaceRichIterable<E>
- Overrides:
anySatisfy
in classAbstractRichIterable<E>
-
allSatisfy
public boolean allSatisfy(Predicate<? super E> predicate)
Description copied from interface:RichIterable
Returns true if the predicate evaluates to true for every element of the iterable or if the iterable is empty. Otherwise, returns false.- Specified by:

in interfaceRichIterable<E>
- Overrides:
allSatisfy
in classAbstractRichIterable<E>
-
noneSatisfy
public boolean noneSatisfy(Predicate<? super E> predicate)
Description copied from interface:RichIterable
Returns true if the predicate evaluates to false for every element of the iterable or if the iterable is empty. Otherwise, returns false.- Specified by:

in interfaceRichIterable<E>
- Overrides:
noneSatisfy
in classAbstractRichIterable<E>
-
detect
public E detect(Predicate<? super E> predicate)
Description copied from interface:RichIterable
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"));
Example using an anonymous inner class:
Person person = people.detect(new Predicate<Person>() { public boolean accept(Person person) { return person.getFirstName().equals("John") && person.getLastName().equals("Smith"); } });

detectOptional
public java.util.Optional<E> detectOptional(Predicate<? super E> predicate)
Description copied from interface:RichIterable

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