      public MutableList<T> asSynchronized()
      Description copied from interface: MutableCollection
      Returns a synchronized wrapper backed by this collection. This is the equivalent of using Collections.synchronizedCollection(this) only with a return type that supports the full iteration protocols available on MutableCollection.

        MutableCollection synchedCollection = collection.asSynchronized();
     ...
  synchedCollection.forEach(each -> ... );
  synchedCollection.select(each -> ... );
  synchedCollection.collect(each -> ... );
      If you want to iterate using an imperative style, you must protect external iterators using a synchronized block. This includes explicit iterators as well as JDK 5 style for loops.

      Description copied from interface: RichIterable
      Returns the first element of an iterable. In the case of a List it is the element at the first index. In the case of any other Collection, it is the first element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.

      The order of Sets are not guaranteed (except for TreeSets and other Ordered Set implementations), so if you use this method, the first element could be any element from the Set.

    • getLast

      public T getLast()
      Description copied from interface: RichIterable
      Returns the last element of an iterable. In the case of a List it is the element at the last index. In the case of any other Collection, it is the last element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.

    • groupBy

      public <V> FastListMultimap<V,T> groupBy(Function<? super T,? extends V> function)
      Description copied from interface: MutableCollection
      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();
         }
     });
      Co-variant example for MutableCollection: 
       MutableMultimap<String, Person> peopleByLastName =
     people.groupBy(Person::getLastName);
