Example 41 with Sum

use of org.eclipse.collections.impl.math.Sum in project eclipse-collections by eclipse.

the class UnifiedMapTest method batchIterable_forEachEntry_emptySet.

@Test
public void batchIterable_forEachEntry_emptySet() {
    // Test forEach on empty set, it should simply do nothing and not throw any exceptions
    Sum sum = new IntegerSum(0);
    BatchIterable<Map.Entry<Integer, Integer>> empty = (BatchIterable<Map.Entry<Integer, Integer>>) UnifiedMap.newMap().entrySet();
    empty.forEach(new EntrySumProcedure(sum));
    Assert.assertEquals(0, sum.getValue());
}

Example 42 with Sum

use of org.eclipse.collections.impl.math.Sum in project eclipse-collections by eclipse.

the class UnifiedMapTest method batchForEachEntry.

@Test
public void batchForEachEntry() {
    // Testing batch size of 1 to 16 with no chains
    BatchIterable<Map.Entry<Integer, Integer>> entries = (BatchIterable<Map.Entry<Integer, Integer>>) UnifiedMap.newWithKeysValues(1, 1, 2, 2, 3, 3, 4, 4).entrySet();
    for (int sectionCount = 1; sectionCount <= 16; ++sectionCount) {
        Sum sum = new IntegerSum(0);
        for (int sectionIndex = 0; sectionIndex < sectionCount; ++sectionIndex) {

    for (int i = 0; i < 5; ++i) {
        collisions.batchForEach(new EntrySumProcedure(sum3), i, 5);
    }
    Assert.assertEquals(78, sum3.getValue());
