示例1: testRandomStream
import java.util.stream.IntStream; //导入方法依赖的package包/类
@Test
public void testRandomStream() {
final int size = 1024 * 1024;
final int[] seeds = {
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41,
43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97};
final byte[] bytes = new byte[size];
for (int seed : seeds) {
final Random random = new Random(seed);
random.nextBytes(bytes);
final BitSet bitSet = BitSet.valueOf(bytes);
final int cardinality = bitSet.cardinality();
final IntStream stream = bitSet.stream();
final int[] array = stream.toArray();
assertEquals(array.length, cardinality);
int nextSetBit = -1;
for (int i=0; i < cardinality; i++) {
nextSetBit = bitSet.nextSetBit(nextSetBit + 1);
assertEquals(array[i], nextSetBit);
}
}
}
示例2: copyOf
import java.util.stream.IntStream; //导入方法依赖的package包/类
/** Returns an immutable array containing all the values from {@code stream}, in order. */
public static ImmutableIntArray copyOf(IntStream stream) {
// Note this uses very different growth behavior from copyOf(Iterable) and the builder.
int[] array = stream.toArray();
return (array.length == 0) ? EMPTY : new ImmutableIntArray(array);
