public interface Stream<T>
extends LinearSeq<T>

An immutable Stream is lazy sequence of elements which may be infinitely long. Its immutability makes it suitable for concurrent programming.

A Stream is composed of a head element and a lazy evaluated tail Stream.

There are two implementations of the Stream interface:

Stream.Empty, which represents the empty Stream.
Stream.Cons, which represents a Stream containing one or more elements.

Methods to obtain a Stream:

 
 // factory methods
 Stream.empty()                  // = Stream.of() = Empty.instance()
 Stream.of(x)                    // = new Cons<>(x, Empty.instance())
 Stream.of(Object...)            // e.g. Stream.of(1, 2, 3)
 Stream.ofAll(Iterable)          // e.g. Stream.ofAll(List.of(1, 2, 3)) = 1, 2, 3
 Stream.ofAll(<primitive array>) // e.g. List.ofAll(1, 2, 3) = 1, 2, 3

 // int sequences
 Stream.from(0)                  // = 0, 1, 2, 3, ...
 Stream.range(0, 3)              // = 0, 1, 2
 Stream.rangeClosed(0, 3)        // = 0, 1, 2, 3

 // generators
 Stream.cons(Object, Supplier)   // e.g. Stream.cons(current, () -> next(current));
 Stream.continually(Supplier)    // e.g. Stream.continually(Math::random);
 Stream.iterate(Object, Function)// e.g. Stream.iterate(1, i -> i * 2);

Factory method applications:

 
 Stream<Integer>       s1 = Stream.of(1);
 Stream<Integer>       s2 = Stream.of(1, 2, 3);
                       // = Stream.of(new Integer[] {1, 2, 3});

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

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

 // cuckoo's egg
 Stream<Integer[]>     s7 = Stream.<Integer[]> of(new Integer[] {1, 2, 3});

Example: Generating prime numbers

 
 // = Stream(2L, 3L, 5L, 7L, ...)
 Stream.iterate(2L, PrimeNumbers::nextPrimeFrom)

 // helpers

 static long nextPrimeFrom(long num) {
     return Stream.from(num + 1).find(PrimeNumbers::isPrime).get();
 }

 static boolean isPrime(long num) {
     return !Stream.rangeClosed(2L, (long) Math.sqrt(num)).exists(d -> num % d == 0);
 }

@GwtIncompatible
default java.util.List<T> asJava()
```
 Description copied from interface: Seq
 Returns an immutable List view of this Seq. Any attempt to modify the view (e.g., via mutator methods) will throw UnsupportedOperationException at runtime.
 This is a view, not a copy. Compared to conversion methods like toJava*():
 
 Creating the view is O(1) (constant time), whereas conversions take O(n), with n = collection size.
 
 Operations on the view have the same performance characteristics as the underlying persistent Vavr collection, while converted collections behave like standard Java collections.
 
 Note: the immutable Java list view throws UnsupportedOperationException before checking method arguments, which may differ from standard Java behavior.
 Specified by:
 
 asJava in interface Seq<T>
 
 Returns:
 
 an immutable List view of this sequence
 - asJava

 Description copied from interface: Traversable
 
 Returns a Traversable formed by pairing elements of this Traversable with elements of another Iterable. Pairing stops when either collection runs out of elements; any remaining elements in the longer collection are ignored.
 The length of the resulting Traversable is the minimum of the lengths of this Traversable and that.
 
 Specified by:
 
 zip in interface LinearSeq<T>
 
 Specified by:
 
 zip in interface Seq<T>

 Parameters:
 
 that - an Iterable providing the second element of each pair
 
 Returns:
 
 a new Traversable containing pairs of corresponding elements
 - zipWith
```
default <U,R> Stream<R> zipWith(@NonNull java.lang.Iterable<? extends U> that,
 java.util.function.BiFunction<? super T,? super U,? extends R> mapper)
```
 Description copied from interface: Traversable
 
 Returns a Traversable by combining elements of this Traversable with elements of another Iterable using a mapping function. Pairing stops when either collection runs out of elements.
 The length of the resulting Traversable is the minimum of the lengths of this Traversable and that.
 
 Specified by:
 
 zipWith in interface LinearSeq<T>
 
 Specified by:
 
 zipWith in interface Seq<T>

 Description copied from interface: Traversable
 
 Returns a Traversable formed by pairing elements of this Traversable with elements of another Iterable, filling in placeholder elements when one collection is shorter than the other.
 The length of the resulting Traversable is the maximum of the lengths of this Traversable and that.
 If this Traversable is shorter than that, thisElem is used as a filler. Conversely, if that is shorter, thatElem is used.
