Examples with ImmutableIntBag org.eclipse.collections.api.bag.primitive.ImmutableIntBag used on opensource projects

Example 1 with ImmutableIntBag

use of org.eclipse.collections.api.bag.primitive.ImmutableIntBag in project eclipse-collections by eclipse.

the class ImmutableBagTestCase method collectInt.

@Override
@Test
public void collectInt() {
    super.collectInt();
    ImmutableIntBag result = this.newBag().collectInt(Integer::parseInt);
    Assert.assertEquals(this.numKeys(), result.sizeDistinct());
    for (int i = 1; i <= this.numKeys(); i++) {
        Assert.assertEquals(i, result.occurrencesOf(i));
    }
}

Example 2 with ImmutableIntBag
