Examples with DoublePredicate java.util.function.DoublePredicate used on opensource projects

Example 1 with DoublePredicate

use of java.util.function.DoublePredicate in project gatk by broadinstitute.

the class MathUtilsUnitTest method testAllMatchDouble.

@Test
public void testAllMatchDouble() {
    for (final double[] array : testArrays) {
        final double[] copy = Arrays.copyOf(array, array.length);
        final DoublePredicate pred = x -> x > -0.5;
        Assert.assertEquals(MathUtils.allMatch(copy, pred), Arrays.stream(copy).allMatch(pred));
        //make sure original array was not affected
        Assert.assertEquals(array, copy);
    }
}

Example 2 with DoublePredicate

    DoublePredicate predicate = val -> val <= 2;
    Predicate<Double> wrapPredicate = predicate::test;
    double expectedValue = 2.0;
    thrown.expectAssertionError("[test] " + shouldNotAccept(wrapPredicate, expectedValue, PredicateDescription.GIVEN).create());
