    MapIterable<String, String> map = this.newMapWithKeysValues("One", "1", "Two", "2", "Three", "3");
    IntIterable actual = map.collectInt(Integer::parseInt);
    Assert.assertEquals(IntHashBag.newBagWith(1, 2, 3), actual.toBag());
}

Example 7 with IntIterable

use of org.eclipse.collections.api.IntIterable in project eclipse-collections by eclipse.

the class AbstractRichIterableTestCase method collectIntWithTarget.

@Test
public void collectIntWithTarget() {
    MutableIntCollection target = new IntArrayList();
    IntIterable result = this.newWith(1, 2, 3, 4).collectInt(PrimitiveFunctions.unboxIntegerToInt(), target);
    Assert.assertSame("Target list sent as parameter not returned", target, result);
    Assert.assertEquals(IntHashBag.newBagWith(1, 2, 3, 4), result.toBag());
}

Example 8 with IntIterable

use of org.eclipse.collections.api.IntIterable in project eclipse-collections by eclipse.

the class CodePointListTest method anySatisfy.

@Override
@Test
public void anySatisfy() {
    Assert.assertTrue(this.newWith(1, 2).anySatisfy(IntPredicates.greaterThan(0)));
    Assert.assertFalse(this.newWith(1, 2).anySatisfy(IntPredicates.equal(0)));
    Assert.assertTrue(this.newWith(31, 32).anySatisfy(IntPredicates.greaterThan(0)));
    Assert.assertTrue(this.newWith(2, 31, 32).anySatisfy(IntPredicates.greaterThan(0)));
    Assert.assertFalse(this.newWith(1, 31, 32).anySatisfy(IntPredicates.equal(0)));
    Assert.assertTrue(this.newWith(32).anySatisfy(IntPredicates.greaterThan(0)));
    IntIterable iterable = this.newWith(0, 1, 2);
    Assert.assertTrue(iterable.anySatisfy(value -> value < 3));
    Assert.assertFalse(iterable.anySatisfy(IntPredicates.greaterThan(3)));
    IntIterable iterable1 = this.classUnderTest();
    int size = iterable1.size();
    Assert.assertEquals(size > 3, iterable1.anySatisfy(IntPredicates.greaterThan(3)));
    Assert.assertEquals(size != 0, iterable1.anySatisfy(IntPredicates.lessThan(3)));
}

Example 9 with IntIterable

use of org.eclipse.collections.api.IntIterable in project eclipse-collections by eclipse.

the class CodePointAdapter method chunk.

@Override
public RichIterable<IntIterable> chunk(int size) {
    if (size <= 0) {
        throw new IllegalArgumentException("Size for groups must be positive but was: " + size);
    }

    if (this.notEmpty()) {
        if (this.size() <= size) {
            result.add(IntLists.immutable.withAll(this));
        } else {
            IntIterator iterator = this.intIterator();
            while (iterator.hasNext()) {
                MutableIntList batch = IntLists.mutable.empty();
                for (int i = 0; i < size && iterator.hasNext(); i++) {
                    batch.add(iterator.next());
                }
                result.add(CodePointList.from(batch));
