All Known Implementing Classes:

DelegatingStream

public interface BaseStream<T,S extends BaseStream<T,S>>

Base interface for stream types such as Stream, IntStream, etc. Contains methods common to all stream types.

Method Summary

Modifier and Type	Method and Description
boolean	isParallel() Returns whether this stream, when executed, would execute in parallel (assuming no further modification of the stream, such as appending further intermediate operations or changing its parallelism).
Iterator<T>	iterator() Returns an iterator for the elements of this stream.
S	parallel() Returns an equivalent stream that is parallel.
S	sequential() Returns an equivalent stream that is sequential.
Spliterator<T>	spliterator() Returns a spliterator for the elements of this stream.
S	unordered() Returns an equivalent stream that is unordered.

Method Detail

iterator

Iterator<T> iterator()

Returns an iterator for the elements of this stream.

This is a terminal operation.

Returns:

the element iterator for this stream

spliterator

Spliterator<T> spliterator()

Returns a spliterator for the elements of this stream.

This is a terminal operation.

Returns:

the element spliterator for this stream

isParallel

boolean isParallel()

Returns whether this stream, when executed, would execute in parallel (assuming no further modification of the stream, such as appending further intermediate operations or changing its parallelism). Calling this method after invoking an intermediate or terminal stream operation method may yield unpredictable results.

Returns:

true if this stream would execute in parallel if executed without further modification otherwise false

sequential

S sequential()

Returns an equivalent stream that is sequential. May return itself, either because the stream was already sequential, or because the underlying stream state was modified to be sequential.

This is an intermediate operation.

Returns:

a sequential stream

parallel

S parallel()

Returns an equivalent stream that is parallel. May return itself, either because the stream was already parallel, or because the underlying stream state was modified to be parallel.

This is an intermediate operation.

Returns:

a parallel stream

unordered

S unordered()

Returns an equivalent stream that is unordered. May return itself if the stream was already unordered.

This is an intermediate operation.

Returns:

an unordered stream
