Example 56 with IntegerSum

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

the class ImmutableUnifiedMapWithHashingStrategyTest 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 57 with IntegerSum

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

the class UnifiedMapWithHashingStrategyTest method batchForEachChains.

private void batchForEachChains(BatchIterable<Integer> batchIterable, int expectedValue) {
    // Testing 1 batch with chains
    Sum sum = new IntegerSum(0);
    // testing getBatchCount returns 1
    int numBatches = batchIterable.getBatchCount(100000);
    for (int i = 0; i < numBatches; ++i) {
        batchIterable.batchForEach(new SumProcedure<>(sum), i, numBatches);
    }
    Assert.assertEquals(1, numBatches);
    Assert.assertEquals(expectedValue, sum.getValue());
    // Testing 3 batches with chains and uneven last batch
    Sum sum2 = new IntegerSum(0);
    for (int i = 0; i < 5; ++i) {
        batchIterable.batchForEach(new SumProcedure<>(sum2), i, 5);
    }
    Assert.assertEquals(expectedValue, sum2.getValue());
}

Example 58 with IntegerSum

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