Example 36 with IntegerSum

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

the class UnifiedMapWithHashingStrategyTest method batchForEachEntry_chains.

    // Testing 1 batch with chains
    Sum sum2 = new IntegerSum(0);
    // testing getBatchCount returns 1
    int batchCount = collisions.getBatchCount(100000);
    for (int i = 0; i < batchCount; ++i) {
        collisions.batchForEach(new EntrySumProcedure(sum2), i, batchCount);
    }
    Assert.assertEquals(1, batchCount);
    Assert.assertEquals(78, sum2.getValue());
    // Testing 3 batches with chains and uneven last batch
    Sum sum3 = new IntegerSum(0);
