adapt

public static <E> MutableList<E> adapt(List<E> list)

toImmutable

public ImmutableList<T> toImmutable()

Description copied from interface: MutableCollection

Converts this MutableCollection to an ImmutableCollection.

Specified by:

toImmutable in interface ListIterable<T>

Specified by:

toImmutable in interface MutableCollection<T>

Specified by:

toImmutable in interface MutableList<T>

asUnmodifiable

public MutableList<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.

Specified by:

asUnmodifiable in interface MutableCollection<T>

Specified by:

asUnmodifiable in interface MutableList<T>

Returns:

an unmodifiable view of this collection.

See Also:

• Collections.unmodifiableCollection(Collection)

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.

Specified by:

asSynchronized in interface MutableCollection<T>

Specified by:

asSynchronized in interface MutableList<T>

Returns:

a synchronized view of this collection.

newEmpty

@Deprecated
public MutableList<T> newEmpty()

Deprecated.

use FastList.newList() instead (inlineable)

Description copied from interface: MutableCollection

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()));

This method is a variant of InternalIterable.forEach(Procedure) that has a signature conflict with Iterable.forEach(java.util.function.Consumer).

Specified by:

each in interface RichIterable<T>

Overrides:

e.g.
people.reverseForEach(person -> LOGGER.info(person.getName()));

Specified by:

reverseForEach in interface ReversibleIterable<T>

reverseForEachWithIndex

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()));

Specified by:

reverseForEachWithIndex in interface ReversibleIterable<T>

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)
    {
        LOGGER.info("Index: " + index + " person: " + person.getName());
    }
});

Specified by:

Specified by:

forEachWithIndex in interface OrderedIterable<T>

Overrides:

forEachWithIndex in class AbstractCollectionAdapter<T>

forEachWithIndex

public void forEachWithIndex(int fromIndex,
 int toIndex,
 ObjectIntProcedure<? super T> objectIntProcedure)

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, (person, index) -> LOGGER.info(person.getName()));

This code would output ted and mary's names.

public <S> boolean corresponds(OrderedIterable<S> other,
 Predicate2<? super T, ? super S> 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.

Specified by:

corresponds in interface OrderedIterable<T>

anySatisfy

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

Description copied from interface: RichIterable

with

public RandomAccessListAdapter<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.

with

public RandomAccessListAdapter<T> with(T... elements)

without

public RandomAccessListAdapter<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 RandomAccessListAdapter<T> withAll(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 RandomAccessListAdapter<T> withoutAll(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.

Description copied from interface: MutableCollection

Filters a collection into a PartitionIterable based on the evaluation of the predicate.

Example using a Java 8 lambda expression:

PartitionIterable<Person> newYorkersAndNonNewYorkers =
    people.partitionWith((Person person, String state) -> person.getAddress().getState().getName().equals(state), "New York");

Co-variant example for MutableCollection:

PartitionMutableCollection<Person> newYorkersAndNonNewYorkers =

flatCollect

public <V> MutableList<V> flatCollect(Function<? super T, ? extends 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);

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);

MutableMultimap<String, Person> peopleByLastName =
    people.groupBy(Person::getLastName);
