    • flatCollect

      public <V> UnifiedSet<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);

      Parameters:

      Returns:
      a new flattened collection produced by applying the given function

    • collectWith

      public <P, A> UnifiedSet<A> collectWith(Function2<? super T,? super P,? extends A> 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)
         {
             return each + parameter;
         }

    • collectIf

      public <V> UnifiedSet<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 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:

    • asSynchronized

      public MutableSet<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.

     ...
  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.

    • chunk

      public RichIterable<RichIterable<T>> chunk(int size)
      Description copied from interface: RichIterable
      Partitions elements in fixed size chunks.
      Specified by:
      chunk in interface RichIterable<T>
      Overrides:
      chunk in class AbstractMutableCollection<T>
      Parameters:
      size - the number of elements per chunk
      Returns:
      A RichIterable containing RichIterables of size size, except the last will be truncated if the elements don't divide evenly.

    • union

      public MutableSet<T> union(SetIterable<? extends T> set)
      Description copied from interface: SetIterable
      Returns the set of all objects that are a member of this or set or both. The union of [1, 2, 3] and [2, 3, 4] is the set [1, 2, 3, 4]. If equal elements appear in both sets, then the output will contain the copy from this.

    • intersect

      public MutableSet<T> intersect(SetIterable<? extends T> set)
      Description copied from interface: SetIterable
      Returns the set of all objects that are members of both this and set. The intersection of [1, 2, 3] and [2, 3, 4] is the set [2, 3]. The output will contain instances from this, not set.

    • difference

      public MutableSet<T> difference(SetIterable<? extends T> subtrahendSet)
      Description copied from interface: SetIterable
      Returns the set of all members of this that are not members of subtrahendSet. The difference of [1, 2, 3] and [2, 3, 4] is [1].

    • symmetricDifference

      public MutableSet<T> symmetricDifference(SetIterable<? extends T> setB)
      Description copied from interface: SetIterable
      Returns the set of all objects that are a member of exactly one of this and setB (elements which are in one of the sets, but not in both). For instance, for the sets [1, 2, 3] and [2, 3, 4], the symmetric difference set is [1, 4] . It is the set difference of the union and the intersection.

    • isSubsetOf

      public boolean isSubsetOf(SetIterable<? extends T> candidateSuperset)
      Description copied from interface: SetIterable
      Returns true if all the members of this are also members of candidateSuperset. For example, [1, 2] is a subset of [1, 2, 3], but [1, 4] is not.
