示例1: ConcatTest
import java.util.Collection; //導入方法依賴的package包/類
public ConcatTest(String scenario, Collection<Integer> c1, Collection<Integer> c2, Collection<Integer> expected) {
this.scenario = scenario;
this.c1 = c1;
this.c2 = c2;
this.expected = expected;
// verify prerequisite
Stream<Integer> s1s = c1.stream();
Stream<Integer> s2s = c2.stream();
Stream<Integer> s1p = c1.parallelStream();
Stream<Integer> s2p = c2.parallelStream();
assertTrue(s1p.isParallel());
assertTrue(s2p.isParallel());
assertFalse(s1s.isParallel());
assertFalse(s2s.isParallel());
assertTrue(s1s.spliterator().hasCharacteristics(Spliterator.ORDERED));
assertTrue(s1p.spliterator().hasCharacteristics(Spliterator.ORDERED));
assertTrue(s2s.spliterator().hasCharacteristics(Spliterator.ORDERED));
assertTrue(s2p.spliterator().hasCharacteristics(Spliterator.ORDERED));

示例2: streamOf
import java.util.Collection; //導入方法依賴的package包/類
private static <T extends QualifiedContent> Stream<T> streamOf(
Collection<TransformInput> inputs,
Function<TransformInput, Collection<T>> mapping) {
Collection<T> list = inputs.stream()
.map(mapping)
.flatMap(Collection::stream)
.collect(Collectors.toList());
if (list.size() >= Runtime.getRuntime().availableProcessors())
return list.parallelStream();
