Example 16 with Longs

use of java8.lang.Longs in project streamsupport by stefan-zobel.

the class ThreadLocalRandomTest method testUnsizedLongsCountSeq.

/**
 * A sequential unsized stream of longs generates at least 100 values
 */
public void testUnsizedLongsCountSeq() {
    LongAdder counter = new LongAdder();
    ThreadLocalRandom r = ThreadLocalRandom.current();
    long size = 100;
    r.longs().limit(size).forEach(x -> {
        counter.increment();
    });
    assertEquals(counter.sum(), size);
}

Example 17 with Longs

use of java8.lang.Longs in project streamsupport by stefan-zobel.

the class SplittableRandomTest method testUnsizedLongsCount.

/**
 * A parallel unsized stream of longs generates at least 100 values
 */
public void testUnsizedLongsCount() {
    LongAdder counter = new LongAdder();
    SplittableRandom r = new SplittableRandom();
    long size = 100;
    r.longs().limit(size).parallel().forEach(x -> counter.increment());
    assertEquals(size, counter.sum());
}

Example 18 with Longs

use of java8.lang.Longs in project streamsupport by stefan-zobel.

the class LongAccumulatorTest method testAccumulateAndGet.

/**
 * accumulate accumulates given value to current, and get returns current value
 */
public void testAccumulateAndGet() {
    LongAccumulator acc = new LongAccumulator(Longs::max, 0L);
    acc.accumulate(2);
    assertEquals(2, acc.get());
    acc.accumulate(-4);
    assertEquals(2, acc.get());

    assertEquals(4, acc.get());
}

Example 19 with Longs

use of java8.lang.Longs in project streamsupport by stefan-zobel.

the class LongAccumulatorTest method testToString.

/**
 * toString returns current value.
 */
public void testToString() {
    LongAccumulator acc = new LongAccumulator(Longs::max, 0L);
    assertEquals("0", acc.toString());
    acc.accumulate(1);
    assertEquals(Long.toString(1), acc.toString());
}

Example 20 with Longs

use of java8.lang.Longs in project streamsupport by stefan-zobel.

the class LongAccumulatorTest method testReset.

/**
 * reset() causes subsequent get() to return zero
 */
public void testReset() {
    LongAccumulator acc = new LongAccumulator(Longs::max, 0L);
    acc.accumulate(2);
    assertEquals(2, acc.get());
