        public <P,​V> ImmutableStack<V> collectWith​(Function2<? super T,​? super P,​? extends V> function,
                                                         P parameter)
        Description copied from interface: RichIterable
        Same as RichIterable.collect(Function) with a Function2 and specified parameter which is passed to the block.

        Example using a Java 8 lambda expression:

         RichIterable<Integer> integers =
             Lists.mutable.with(1, 2, 3).collectWith((each, parameter) -> each + parameter, Integer.valueOf(1));
         

        Example using an anonymous inner class:

         Function2<Integer, Integer, Integer> addParameterFunction =
             new Function2<Integer, Integer, Integer>()
             {
                 public Integer value(Integer each, Integer parameter)

        Returns:

      • collectIf

        public <V> ImmutableStack<V> collectIf​(Predicate<? super T> predicate,
                                               Function<? super T,​? extends V> function)
        Description copied from interface: RichIterable
        Returns a new collection with the results of applying the specified function on each element of the source collection, but only for those elements which return true upon evaluation of the predicate. This is the optimized equivalent of calling iterable.select(predicate).collect(function).

        Example using a Java 8 lambda and method reference:

         RichIterable<String> strings = Lists.mutable.with(1, 2, 3).collectIf(e -> e != null, Object::toString);
         

        Example using Predicates factory:

         RichIterable<String> strings = Lists.mutable.with(1, 2, 3).collectIf(Predicates.notNull(), Functions.getToString());

      • flatCollect

        public <V> ImmutableStack<V> flatCollect​(Function<? super T,​? extends java.lang.Iterable<V>> function)
        Description copied from interface: RichIterable
        flatCollect is a special case of RichIterable.collect(Function). With collect, when the Function returns a collection, the result is a collection of collections. flatCollect outputs a single "flattened" collection instead. This method is commonly called flatMap.

        Consider the following example where we have a Person class, and each Person has a list of Address objects. Take the following Function:

         Function<Person, List<Address>> addressFunction = Person::getAddresses;
         RichIterable<Person> people = ...;
         
        Using collect returns a collection of collections of addresses.
         RichIterable<List<Address>> addresses = people.collect(addressFunction);
         
        Using flatCollect returns a single flattened list of addresses.
         RichIterable<Address> addresses = people.flatCollect(addressFunction);

        a new flattened collection produced by applying the given function
      • groupBy

        public <V> ImmutableListMultimap<V,​T> groupBy​(Function<? super T,​? extends V> function)
        Description copied from interface: RichIterable
        For each element of the iterable, the function is evaluated and the results of these evaluations are collected into a new multimap, where the transformed value is the key and the original values are added to the same (or similar) species of collection as the source iterable.

        Example using a Java 8 method reference:

         Multimap<String, Person> peopleByLastName =
             people.groupBy(Person::getLastName);
         

        Example using an anonymous inner class:

         Multimap<String, Person> peopleByLastName =
             people.groupBy(new Function<Person, String>()
             {
                 public String valueOf(Person person)
                 {
                     return person.getLastName();
                 }
             });

      • zip

        Description copied from interface: OrderedIterable
        Returns a OrderedIterable formed from this OrderedIterable and another Iterable by combining corresponding elements in pairs. The second Iterable should also be ordered. If one of the two Iterables is longer than the other, its remaining elements are ignored.

        Specified by:
        chunk in interface RichIterable<T>
        Parameters:
        size - the number of elements per chunk
        Returns:

      • each

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

             }
         });

        Description copied from interface: OrderedIterable
        Returns true if both OrderedIterables have the same length and predicate returns true for all corresponding elements e1 of this OrderedIterable and e2 of other.
