Example 21 with Sum

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

the class IterateTest method injectIntoWithHashSet.

@Test
public void injectIntoWithHashSet() {
    Sum result = new IntegerSum(0);
    Integer parameter = 2;
    MutableSet<Integer> integers = Interval.toSet(1, 5);
    this.basicTestDoubleSum(result, integers, parameter);
}

Example 22 with Sum

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

the class IterateTest method basicTestDoubleSum.

    Function3<Sum, Integer, Integer, Sum> function = (sum, element, withValue) -> sum.add(element.intValue() * withValue.intValue());
    Sum sumOfDoubledValues = Iterate.injectIntoWith(newResult, newIntegers, function, newParameter);
    Assert.assertEquals(30, sumOfDoubledValues.getValue().intValue());
}
