List (Vavr 0.10.4 API)

Type Parameters:

T - Component type of the List

All Superinterfaces:

Foldable<T>, Function<Integer,T>, Function1<Integer,T>, Iterable<T>, LinearSeq<T>, PartialFunction<Integer,T>, Seq<T>, Serializable, Traversable<T>, Value<T>

All Known Implementing Classes:

List.Cons, List.Nil
```
public interface List<T>
extends LinearSeq<T>
```
An immutable List is an eager sequence of elements. Its immutability makes it suitable for concurrent programming.
A List is composed of a head element and a tail List.
There are two implementations of the List interface:
- List.Nil, which represents the empty List.
- List.Cons, which represents a List containing one or more elements.
A List is a Stack in the sense that it stores elements allowing a last-in-first-out (LIFO) retrieval.
Stack API:
Methods to obtain a List:
```
 
 // factory methods
 List.empty() // = List.of() = Nil.instance()
 List.of(x) // = new Cons<>(x, Nil.instance())
 List.of(Object...) // e.g. List.of(1, 2, 3)
 List.ofAll(Iterable) // e.g. List.ofAll(Stream.of(1, 2, 3)) = 1, 2, 3
 List.ofAll(<primitive array>) // e.g. List.of(new int[] {1, 2, 3}) = 1, 2, 3

 // int sequences
 List.range(0, 3) // = 0, 1, 2
 List.rangeClosed(0, 3) // = 0, 1, 2, 3
 
 
```
Note: A List is primarily a Seq and extends Stack for technical reasons (so Stack does not need to wrap List).
If operating on a List, please prefer
- prepend(Object) over push(Object)
- prependAll(Iterable) over pushAll(Iterable)
- tail() over pop()
- tailOption() over popOption()
Factory method applications:
```
 
 List<Integer> s1 = List.of(1);
 List<Integer> s2 = List.of(1, 2, 3);
 // = List.of(new Integer[] {1, 2, 3});

 List<int[]> s3 = List.ofAll(1, 2, 3);
 List<List<Integer>> s4 = List.ofAll(List.of(1, 2, 3));

 List<Integer> s5 = List.ofAll(1, 2, 3);
 List<Integer> s6 = List.ofAll(List.of(1, 2, 3));

 // cuckoo's egg
 List<Integer[]> s7 = List.<Integer[]> of(new Integer[] {1, 2, 3});
 
 
```
Example: Converting a String to digits
```
 
 // = List(1, 2, 3)
 List.of("123".toCharArray()).map(c -> Character.digit(c, 10))
 
 
```

```
@GwtIncompatible
default List<T> asJava()
```
 Description copied from interface: Seq
 Creates an immutable List view on top of this Seq, i.e. calling mutators will result in UnsupportedOperationException at runtime.
 The difference to conversion methods toJava*() is that
 - A view is created in O(1) (constant time) whereas conversion takes O(n) (linear time), with n = collection size.
 - The operations on a view have the same performance characteristics than the underlying persistent Vavr collection whereas the performance characteristics of a converted collection are those of the Java standard collections.
 Please note that our immutable java.util.List view throws UnsupportedOperationException before checking method arguments. Java does handle this case inconsistently.

 Returns:
 
 A new immutable Collection view on this Traversable.
