      • asSynchronized

        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. 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.

      • newEmpty

        @Deprecated
        public MutableList<T> newEmpty()
        Deprecated.
        use FastList.newList() instead (inlineable)
        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.

      • each

        public void each​(Procedure<? super T> procedure)
        Description copied from interface: RichIterable
        The procedure is executed for each element in the iterable.

        Example using a Java 8 lambda expression:

         people.each(person -> LOGGER.info(person.getName()));
         

        Example using an anonymous inner class:

         people.each(new Procedure<Person>()
         {
             public void value(Person person)
             {
                 LOGGER.info(person.getName());
             }
         });
         
        This method is a variant of InternalIterable.forEach(Procedure) that has a signature conflict with Iterable.forEach(java.util.function.Consumer).

      • reverseForEach

        public void reverseForEach​(Procedure<? super T> procedure)
        Description copied from interface: ReversibleIterable
        Evaluates the procedure for each element of the list iterating in reverse order.

        public void reverseForEachWithIndex​(ObjectIntProcedure<? super T> procedure)
        Description copied from interface: ReversibleIterable
        Evaluates the procedure for each element and it's index in reverse order.
        e.g.
         people.reverseForEachWithIndex((person, index) ->
                 LOGGER.info("Index: " + index + " person: " + person.getName()));

      • forEachWithIndex

        public void forEachWithIndex​(ObjectIntProcedure<? super T> objectIntProcedure)
        Description copied from interface: InternalIterable
        Iterates over the iterable passing each element and the current relative int index to the specified instance of ObjectIntProcedure.

        Example using a Java 8 lambda:

         people.forEachWithIndex((Person person, int index) -> LOGGER.info("Index: " + index + " person: " + person.getName()));
         

        Example using an anonymous inner class:

         people.forEachWithIndex(new ObjectIntProcedure<Person>()
         {
             public void value(Person person, int index)
             {

        Description copied from interface: OrderedIterable
        Iterates over the section of the iterable covered by the specified inclusive indexes. The indexes are both inclusive.
        e.g.
         OrderedIterable<People> people = FastList.newListWith(ted, mary, bob, sally)
         people.forEachWithIndex(0, 1, new ObjectIntProcedure<Person>()
         {

             {
                  LOGGER.info(person.getName());

      • detect

        public T detect​(Predicate<? super T> predicate)
        Description copied from interface: RichIterable
        Returns the first element of the iterable for which the predicate evaluates to true or null in the case where no element returns true. This method is commonly called find.

      • count

        public int count​(Predicate<? super T> predicate)

        Description copied from interface: OrderedIterable
        Returns true if both OrderedIterables have the same length and predicate returns true for all corresponding elements e1 of this OrderedIterable and e2 of other. The predicate is evaluated for each element at the same position of each OrderedIterable in a forward iteration order. This is a short circuit pattern.

      • anySatisfy

        public boolean anySatisfy​(Predicate<? super T> predicate)

        Description copied from interface: RichIterable
        Returns the final result of evaluating function using each element of the iterable and the previous evaluation result as the parameters. The injected value is used for the first parameter of the first evaluation, and the current item in the iterable is used as the second parameter. This method is commonly called fold or sometimes reduce.

      • with

        public ListAdapter<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 ListAdapter<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.

        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.
