public interface ListIterable<T>
extends ReversibleIterable<T>
An iterable whose items are ordered and may be accessed directly by index. A reverseForEach internal iterator is available iterating over the indexed iterable in reverse, starting from the end and going to the beginning. Additionally, internal iterators are available for batching style iteration which is useful for parallel processing.

  • Method Details

    • get

      T get​(int index)
      Returns the item at the specified position in this list iterable.

    • lastIndexOf

      int lastIndexOf​(Object o)
      Returns the index of the last occurrence of the specified item in this list, or -1 if this list does not contain the item.

    • getFirst

      T getFirst()
      Returns the item at index 0 of the container. If the container is empty, null is returned. If null is a valid item of the container, then a developer will need to check to see if the container is empty first.

      getFirst in interface OrderedIterable<T>
      Specified by:
      getFirst in interface RichIterable<T>

    • getLast

      T getLast()
      Returns the item at index (size() - 1) of the container. If the container is empty, null is returned. If null is a valid item of the container, then a developer will need to check to see if the container is empty first.

    • flatCollect

      <V> ListIterable<V> flatCollect​(Function<? super T,​? extends 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);

    • groupBy

      <V> ListMultimap<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();
         }
     });
