Examples with Sum org.eclipse.collections.impl.math.Sum used on opensource projects

Example 86 with Sum

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

the class UnifiedMapTest method batchIterable_forEachEmptyBatchIterable.

private void batchIterable_forEachEmptyBatchIterable(BatchIterable<Integer> batchIterable) {
    // Test forEach on empty set, it should simply do nothing and not throw any exceptions
    Sum sum = new IntegerSum(0);
    batchIterable.batchForEach(new SumProcedure<>(sum), 0, batchIterable.getBatchCount(1));
    Assert.assertEquals(0, sum.getValue());
}

Example 87 with Sum

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

the class ImmutableUnifiedMapTest method batchForEach.

@Test
public void batchForEach() {
    Sum sum = new IntegerSum(0);
    BatchIterable<String> integerBatchIterable = (BatchIterable<String>) this.classUnderTest();
    integerBatchIterable.batchForEach(each -> sum.add(Integer.valueOf(each)), 0, 1);
    Assert.assertEquals(10, sum.getValue());
}

Example 88 with Sum

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