Examples with Longs java8.lang.Longs used on opensource projects

Example 1 with Longs

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

the class LongAccumulatorTest method testDoubleValue.

/**
 * doubleValue returns current value.
 */
public void testDoubleValue() {
    LongAccumulator acc = new LongAccumulator(Longs::max, 0L);
    assertEquals(0.0, acc.doubleValue());
    acc.accumulate(1);
    assertEquals(1.0, acc.doubleValue());
}

Example 2 with Longs

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

the class SplittableRandomTest method testUnsizedLongsCountSeq.

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

Example 3 with Longs

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

the class SplittableRandomTest method testLongsCount.

/**
 * A parallel sized stream of longs generates the given number of values
 */
public void testLongsCount() {
    LongAdder counter = new LongAdder();
    SplittableRandom r = new SplittableRandom();
    long size = 0;
    for (int reps = 0; reps < REPS; ++reps) {
        counter.reset();
        r.longs(size).parallel().forEach(x -> counter.increment());
        assertEquals(size, counter.sum());
        size += 524959;
    }
}

    assertEquals(0, acc.intValue());
    acc.accumulate(1);
    assertEquals(1, acc.intValue());
}
