      • with

        public MutableBag<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.

      • without

        public MutableBag<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. 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.without("1");
         list = list.without("2");
         return list;
         
        In the case of FixedSizeCollection a new instance of MutableCollection will be returned by without, 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 remove on itself.

      • withAll

        public MutableBag<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. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling addAll on itself.

      • withoutAll

        public MutableBag<T> withoutAll​(java.lang.Iterable<? extends T> elements)
        Description copied from interface: MutableCollection
        This method allows mutable and fixed size collections the ability to remove multiple 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 removeAll. 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.withoutAll(FastList.newListWith("1", "2"));
         
        In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withoutAll, 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 removeAll on itself.

      • asSynchronized

        public MutableBag<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.

        Specified by:
        asSynchronized in interface MutableBag<T>
        Specified by:
        asSynchronized in interface MutableCollection<T>

      • asUnmodifiable

        public MutableBag<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.

        Description copied from interface: MutableBagIterable
        Add number of occurrences for an item. If the item does not exist, then the item is added to the bag.

        For Example:

         MutableBagIterable<String> names = Bags.mutable.of("A", "B", "B");
         Assert.assertEquals(4, names.addOccurrences("A", 3));

      • collect

        public <V> MutableBag<V> collect​(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. This method is also commonly called transform or map.

        Example using a Java 8 lambda expression:

         RichIterable<String> names =
             people.collect(person -> person.getFirstName() + " " + person.getLastName());

      • flatCollect

        public <V> MutableBag<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);

      • topOccurrences

        public MutableList<ObjectIntPair<T>> topOccurrences​(int count)
        Description copied from interface: Bag

      • collectIf

        public <V> MutableBag<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());

      • groupBy

        public <V> MutableBagMultimap<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);

      • newEmpty

        public MutableBag<T> newEmpty()
        Description copied from interface: MutableCollection
        Creates a new empty mutable version of the same collection type. For example, if this instance is a FastList, this method will return a new empty FastList. If the class of this instance is immutable or fixed size (i.e. SingletonList) then a mutable alternative to the class will be provided.

      • reject

        public MutableBag<T> reject​(Predicate<? super T> predicate)
        Description copied from interface: RichIterable
        Returns all elements of the source collection that return false when evaluating of the predicate. This method is also sometimes called filterNot and is the equivalent of calling iterable.select(Predicates.not(predicate)).

        Example using a Java 8 lambda expression:

         RichIterable<Person> rejected =
             people.reject(person -> person.person.getLastName().equals("Smith"));

      • toStringOfItemToCount

        public java.lang.String toStringOfItemToCount()
        Description copied from interface: Bag
        Returns a string representation of this bag. The string representation consists of a list of element-count mappings.
