      • UnmodifiableMutableSet

        UnmodifiableMutableSet​(MutableSet<? extends T> mutableSet)
    • Method Detail

      • of

        public static <E,​S extends java.util.Set<E>> UnmodifiableMutableSet<E> of​(S set)
        This method will take a MutableSet and wrap it directly in a UnmodifiableMutableSet. It will take any other non-Eclipse-Collections set and first adapt it will a SetAdapter, and then return a UnmodifiableMutableSet that wraps the adapter.
      • getMutableSet

        protected MutableSet<T> getMutableSet()
      • asUnmodifiable

        public MutableSet<T> asUnmodifiable()
        Description copied from interface: MutableCollection
        Returns an unmodifiable view of this collection. This is the equivalent of using Collections.unmodifiableCollection(this) with a return type that supports the full iteration protocols available on MutableCollection. Methods which would mutate the underlying collection will throw UnsupportedOperationExceptions.

        asUnmodifiable in interface MutableCollection<T>
        Specified by:
        asUnmodifiable in interface MutableSet<T>
        Overrides:
        asUnmodifiable in class AbstractUnmodifiableMutableCollection<T>
        Returns:
        an unmodifiable view of this collection.
        See Also:
        Collections.unmodifiableCollection(Collection)
      • 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. The preferred way of iterating over a synchronized collection is to use the internal iteration methods which are properly synchronized internally.
          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.

      • flatCollect

        public <V> MutableSet<V> flatCollect​(Function<? super T,​? extends java.lang.Iterable<V>> function)
        Description copied from interface: MutableCollection
        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);
         
        Co-variant example for MutableCollection:
         Function<Person, List<Address>> addressFunction = Person::getAddresses;
         MutableCollection<Person> people = ...;
         MutableCollection<List<Address>> addresses = people.collect(addressFunction);
         MutableCollection<Address> addresses = people.flatCollect(addressFunction);

        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;
                 }
             };
         RichIterable<Integer> integers =
             Lists.mutable.with(1, 2, 3).collectWith(addParameterFunction, Integer.valueOf(1));
         
        Co-variant example for MutableCollection:
         MutableCollection<Integer> integers =
             Lists.mutable.with(1, 2, 3).collectWith((each, parameter) -> each + parameter, Integer.valueOf(1));

      • groupBy

        public <V> MutableSetMultimap<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:

        that - The RichIterable providing the second half of each result pair
        Returns:
        A new RichIterable containing pairs consisting of corresponding elements of this RichIterable and that. The length of the returned RichIterable is the minimum of the lengths of this RichIterable and that.
      • 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.

      • with

        public MutableSet<T> with​(T element)
        Description copied from interface: MutableCollection
        This method allows mutable and fixed size collections the ability to add elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new element to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:
         MutableCollection<String> list = list.with("1");
         list = list.with("2");
         return list;
         
        In the case of FixedSizeCollection a new instance of MutableCollection will be returned by with, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling add on itself.

        public MutableSet<T> without​(T element)
        Description copied from interface: MutableCollection
        This method allows mutable and fixed size collections the ability to remove elements from their existing elements. In order to support fixed size a new instance of a collection would have to be returned containing the elements that would be left from the original collection after calling remove.

      • withAll

        public MutableSet<T> withAll​(java.lang.Iterable<? extends T> elements)
        Description copied from interface: MutableCollection
        This method allows mutable and fixed size collections the ability to add multiple elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new elements to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:
         MutableCollection<String> list = list.withAll(FastList.newListWith("1", "2"));
         
        In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withAll, and any variables that previously referenced the original collection will need to be redirected to reference the new instance.
