Examples with MutableDoubleList org.eclipse.collections.api.list.primitive.MutableDoubleList used on opensource projects

Example 1 with MutableDoubleList

use of org.eclipse.collections.api.list.primitive.MutableDoubleList in project eclipse-collections by eclipse.

the class ArrayListIterateTest method collectDoubleOverOptimizeLimit.

@Test
public void collectDoubleOverOptimizeLimit() {
    ArrayList<Integer> list = new ArrayList<>(Interval.zeroTo(OVER_OPTIMIZED_LIMIT));
    MutableDoubleList actual = ArrayListIterate.collectDouble(list, PrimitiveFunctions.unboxIntegerToDouble());
    DoubleArrayList expected = new DoubleArrayList(list.size());
    for (int i = 0; i <= OVER_OPTIMIZED_LIMIT; i++) {
        expected.add((double) i);
    }
    Assert.assertEquals(expected, actual);
}

Example 2 with MutableDoubleList

use of org.eclipse.collections.api.list.primitive.MutableDoubleList in project eclipse-collections by eclipse.

the class ArrayListIterateTest method collectDoubleWithTargetOverOptimizeLimit.

@Test
public void collectDoubleWithTargetOverOptimizeLimit() {
    ArrayList<Integer> list = new ArrayList<>(Interval.zeroTo(OVER_OPTIMIZED_LIMIT));
    MutableDoubleList target = new DoubleArrayList();
    MutableDoubleList actual = ArrayListIterate.collectDouble(list, PrimitiveFunctions.unboxIntegerToDouble(), target);
    DoubleArrayList expected = new DoubleArrayList(list.size());
    for (int i = 0; i <= OVER_OPTIMIZED_LIMIT; i++) {
        expected.add((double) i);
    }
    Assert.assertEquals(expected, actual);
