      • FlatCollectLongToObjectIterable

        public FlatCollectLongToObjectIterable​(LongIterable iterable,

    • Method Detail

      • each

        public void each​(Procedure<? super V> 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()));
        This method is a variant of InternalIterable.forEach(Procedure) that has a signature conflict with Iterable.forEach(java.util.function.Consumer).
        See Also:
        InternalIterable.forEach(Procedure), Iterable.forEach(java.util.function.Consumer)

      • forEachWithIndex

        public void forEachWithIndex​(ObjectIntProcedure<? super V> 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 interface InternalIterable<V>
        Overrides:
        forEachWithIndex in class AbstractRichIterable<V>

      • forEachWith

        public <P> void forEachWith​(Procedure2<? super V,​? 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);
        Specified by:

      • iterator

        public java.util.Iterator<V> iterator()

      • detect

        public V detect​(Predicate<? super V> 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"));
        Specified by:
        detect in interface RichIterable<V>
        Overrides:
        detect in class AbstractRichIterable<V>

      • detectOptional

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

        Specified by:
        detectOptional in interface RichIterable<V>
        Overrides:
        detectOptional in class AbstractRichIterable<V>

      • anySatisfy

        public boolean anySatisfy​(Predicate<? super V> 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 interface RichIterable<V>
        Overrides:
        anySatisfy in class AbstractRichIterable<V>

      • anySatisfyWith

        public <P> boolean anySatisfyWith​(Predicate2<? super V,​? super P> predicate,
                                  P parameter)
        Description copied from interface: RichIterable
        Returns true if the predicate evaluates to true for any element of the collection, or return false. Returns false if the collection is empty.
        Specified by:
        anySatisfyWith in interface RichIterable<V>
        Overrides:
        anySatisfyWith in class AbstractRichIterable<V>

      • noneSatisfyWith

        public <P> boolean noneSatisfyWith​(Predicate2<? super V,​? super P> predicate,

        Description copied from interface: RichIterable
        Returns true if the predicate evaluates to false for every element of the collection, or return false. Returns true if the collection is empty.
        Specified by:
