```
public LongStreamEx unordered()
```
    Description copied from interface: java.util.stream.BaseStream
    
    Returns an equivalent stream that is unordered. May return itself, either because the stream was already unordered, or because the underlying stream state was modified to be unordered.

  - onClose
```
public LongStreamEx onClose(Runnable closeHandler)
```
    Description copied from interface: java.util.stream.BaseStream
    
    Returns an equivalent stream with an additional close handler. Close handlers are run when the BaseStream.close() method is called on the stream, and are executed in the order they were added. All close handlers are run, even if earlier close handlers throw exceptions. If any close handler throws an exception, the first exception thrown will be relayed to the caller of close(), with any remaining exceptions added to that exception as suppressed exceptions (unless one of the remaining exceptions is the same exception as the first exception, since an exception cannot suppress itself.) May return itself.
    This is an intermediate operation.

```
public LongStreamEx peek(LongConsumer action)
```
    Description copied from interface: java.util.stream.LongStream
    
    Returns a stream consisting of the elements of this stream, additionally performing the provided action on each element as elements are consumed from the resulting stream.
    This is an intermediate operation.
    For parallel stream pipelines, the action may be called at whatever time and in whatever thread the element is made available by the upstream operation. If the action modifies shared state, it is responsible for providing the required synchronization.
    
    Specified by:
    
    peek in interface LongStream
    
    Parameters:
    
    action - a non-interfering action to perform on the elements as they are consumed from the stream
    
    Returns:
    
    the new stream
  - peekFirst
```
public LongStreamEx peekFirst(LongConsumer action)
```
    Returns a stream consisting of the elements of this stream, additionally performing the provided action on the first stream element when it's consumed from the resulting stream.
    This is an intermediate operation.
    The action is called at most once. For parallel stream pipelines, it's not guaranteed in which thread it will be executed, so if it modifies shared state, it is responsible for providing the required synchronization.
    Note that the action might not be called at all if the first element is not consumed from the input (for example, if there's short-circuiting operation downstream which stopped the stream before the first element).
    This method exists mainly to support debugging.
    
    Parameters:
    
    action - a non-interfering action to perform on the first stream element as it is consumed from the stream
    
    Returns:
    
    the new stream
    
    Since:
    
    0.6.0
  - peekLast
```
public LongStreamEx peekLast(LongConsumer action)
```
    Returns a stream consisting of the elements of this stream, additionally performing the provided action on the last stream element when it's consumed from the resulting stream.
    This is an intermediate operation.
    The action is called at most once. For parallel stream pipelines, it's not guaranteed in which thread it will be executed, so if it modifies shared state, it is responsible for providing the required synchronization.
    Note that the action might not be called at all if the last element is not consumed from the input (for example, if there's short-circuiting operation downstream).
    This method exists mainly to support debugging.
    
    Parameters:
    
    action - a non-interfering action to perform on the first stream element as it is consumed from the stream
    
    Returns:
    
    the new stream

  - limit
```
public LongStreamEx limit(long maxSize)
```
    Description copied from interface: java.util.stream.LongStream
    
    Returns a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length.
    This is a short-circuiting stateful intermediate operation.
    
    Specified by:
    
    limit in interface LongStream
    
    Parameters:
    
    maxSize - the number of elements the stream should be limited to
    
    Returns:
    
    the new stream
  - skip
```
public LongStreamEx skip(long n)
```
    Description copied from interface: java.util.stream.LongStream
    
    Returns a stream consisting of the remaining elements of this stream after discarding the first n elements of the stream. If this stream contains fewer than n elements then an empty stream will be returned.
    This is a stateful intermediate operation.
    
    Specified by:
    
    skip in interface LongStream
    
    Parameters:
    
    n - the number of leading elements to skip
    
    Returns:
    
    the new stream
  - skipOrdered
```
public LongStreamEx skipOrdered(long n)
```
    Returns a stream consisting of the remaining elements of this stream after discarding the first n elements of the stream. If this stream contains fewer than n elements then an empty stream will be returned.
    This is a stateful quasi-intermediate operation. Unlike skip(long) it skips the first elements even if the stream is unordered. The main purpose of this method is to workaround the problem of skipping the first elements from non-sized source with further parallel processing and unordered terminal operation (such as forEach(LongConsumer)). This problem was fixed in OracleJDK 8u60.
    Also it behaves much better with infinite streams processed in parallel. For example, LongStreamEx.iterate(0L, i->i+1).skip(1).limit(100).parallel().toArray() will likely to fail with OutOfMemoryError, but will work nicely if skip is replaced with skipOrdered.
    For sequential streams this method behaves exactly like skip(long).
    
    Parameters:
    
    n - the number of leading elements to skip
    
    Returns:
    
    the new stream
    
    Throws:
    
    IllegalArgumentException - if n is negative

```
public void forEach(LongConsumer action)
```
    Description copied from interface: java.util.stream.LongStream
    
    Performs an action for each element of this stream.
    This is a terminal operation.
    For parallel stream pipelines, this operation does not guarantee to respect the encounter order of the stream, as doing so would sacrifice the benefit of parallelism. For any given element, the action may be performed at whatever time and in whatever thread the library chooses. If the action accesses shared state, it is responsible for providing the required synchronization.
    
    Specified by:
    
    forEach in interface LongStream
    
    Parameters:
    
    action - a non-interfering action to perform on the elements

```
public void forEachOrdered(LongConsumer action)
```
    Description copied from interface: java.util.stream.LongStream

  - reduce
```
public long reduce(long identity,
                   LongBinaryOperator op)
```
    Description copied from interface: java.util.stream.LongStream
    Performs a reduction on the elements of this stream, using the provided identity value and an associative accumulation function, and returns the reduced value. This is equivalent to:
```
     long result = identity;
     for (long element : this stream)
         result = accumulator.applyAsLong(result, element)
     return result;
 
```
    but is not constrained to execute sequentially.
    The identity value must be an identity for the accumulator function. This means that for all x, accumulator.apply(identity, x) is equal to x. The accumulator function must be an associative function.
    This is a terminal operation.
    Specified by:
    
    reduce in interface LongStream
    
    Parameters:
    
    identity - the identity value for the accumulating function

```
public OptionalLong reduce(LongBinaryOperator op)
```
    Description copied from interface: java.util.stream.LongStream
    Performs a reduction on the elements of this stream, using an associative accumulation function, and returns an OptionalLong describing the reduced value, if any. This is equivalent to:
```
     boolean foundAny = false;
     long result = null;
     for (long element : this stream) {
         if (!foundAny) {
             foundAny = true;
             result = element;
         }
         else
             result = accumulator.applyAsLong(result, element);
     }
     return foundAny ? OptionalLong.of(result) : OptionalLong.empty();

    Parameters:

  - foldLeft
```
public OptionalLong foldLeft(LongBinaryOperator accumulator)
```
    Folds the elements of this stream using the provided accumulation function, going left to right. This is equivalent to:
```
 
     boolean foundAny = false;
     long result = 0;
     for (long element : this stream) {
         if (!foundAny) {
             foundAny = true;
             result = element;
         }
         else
             result = accumulator.apply(result, element);
     }
     return foundAny ? OptionalLong.of(result) : OptionalLong.empty();
 
 
```
    This is a terminal operation.
    This method cannot take all the advantages of parallel streams as it must process elements strictly left to right. If your accumulator function is associative, consider using reduce(LongBinaryOperator) method.
    For parallel stream it's not guaranteed that accumulator will always be executed in the same thread.
    Parameters:
    
    accumulator - a non-interfering , stateless function for incorporating an additional element into a result

                     BiConsumer<R,R> combiner)
```
    Performs a mutable reduction operation on the elements of this stream. A mutable reduction is one in which the reduced value is a mutable result container, such as an ArrayList, and elements are incorporated by updating the state of the result rather than by replacing the result. This produces a result equivalent to:
```
     R result = supplier.get();
     for (long element : this stream)
         accumulator.accept(result, element);
     return result;
 
```
    Like LongStream.reduce(long, LongBinaryOperator), collect operations can be parallelized without requiring additional synchronization.

    Returns a stream consisting of all elements from this stream starting from the first element which does not match the given predicate. If the predicate is true for all stream elements, an empty stream is returned.
    This is a stateful operation. It can be either intermediate or quasi-intermediate. When using with JDK 1.9 or higher it calls the corresponding JDK 1.9 implementation. When using with JDK 1.8 it uses own implementation.

```
public LongStreamEx prefix(LongBinaryOperator op)
```
    Returns a stream containing cumulative results of applying the accumulation function going left to right.
    This is a stateful quasi-intermediate operation.
    This operation resembles scanLeft(LongBinaryOperator), but unlike scanLeft this operation is intermediate and accumulation function must be associative.
    This method cannot take all the advantages of parallel streams as it must process elements strictly left to right. Using an unordered source or removing the ordering constraint with unordered() may improve the parallel processing speed.
    
    Parameters:
    
    op - an associative , non-interfering , stateless function for computing the next element based on the previous one
    
    Returns:

  - chain
```
public <U> U chain(Function<? super LongStreamEx,U> mapper)
```
    Applies the supplied function to this stream and returns the result of the function.
    This method can be used to add more functionality in the fluent style. For example, consider user-defined static method batches(stream, n) which breaks the stream into batches of given length. Normally you would write batches(StreamEx.of(input).map(...), 10).filter(...). Using the chain() method you can write in more fluent manner: StreamEx.of(input).map(...).chain(s -> batches(s, 10)).filter(...).
    You could even go further and define a method which returns a function like <T> UnaryOperator<StreamEx<T>> batches(int n) and use it like this: StreamEx.of(input).map(...).chain(batches(10)).filter(...).
    
    Type Parameters:
    
    U - the type of the function result.
    
    Parameters:

```
public static LongStreamEx iterate(long seed,
                                   LongUnaryOperator f)
```
    Returns an infinite sequential ordered LongStreamEx produced by iterative application of a function f to an initial element seed, producing a stream consisting of seed, f(seed), f(f(seed)), etc.
    The first element (position 0) in the LongStreamEx will be the provided seed. For n > 0, the element at position n, will be the result of applying the function f to the element at position n - 1.
    
    Specified by:
    
    iterate in interface LongStream
    
    Parameters:
    
    seed - the initial element
    
    f - a function to be applied to to the previous element to produce a new element
    
    Returns:

                                   LongUnaryOperator f)
```
    Returns a sequential ordered LongStreamEx produced by iterative application of a function to an initial element, conditioned on satisfying the supplied predicate. The stream terminates as soon as the predicate function returns false.
    LongStreamEx.iterate should produce the same sequence of elements as produced by the corresponding for-loop:
```
     for (long index=seed; predicate.test(index); index = f.apply(index)) { 
         ... 
     }
 
```
    The resulting sequence may be empty if the predicate does not hold on the seed value. Otherwise the first element will be the supplied seed value, the next element (if present) will be the result of applying the function f to the seed value, and so on iteratively until the predicate indicates that the stream should terminate.
    Parameters:
    
    seed - the initial element
    
    predicate - a predicate to apply to elements to determine when the stream must terminate.
    
    f - a function to be applied to the previous element to produce a new element

  - produce
```
public static LongStreamEx produce(Predicate<LongConsumer> producer)
```
    Return an ordered stream produced by consecutive calls of the supplied producer until it returns false.
    The producer function may call the passed consumer any number of times and return true if the producer should be called again or false otherwise. It's guaranteed that the producer will not be called anymore, once it returns false.
    This method is particularly useful when producer changes the mutable object which should be left in known state after the full stream consumption. Note however that if a short-circuiting operation is used, then the final state of the mutable object cannot be guaranteed.
    
    Parameters:
    
    producer - a predicate which calls the passed consumer to emit stream element(s) and returns true if it producer should be applied again.
    
    Returns:
    
    the new stream
