Example 1 with MutableDoubleCollection

use of org.eclipse.collections.api.collection.primitive.MutableDoubleCollection in project eclipse-collections by eclipse.

the class AbstractLazyIterableTestCase method collectDoubleWithTarget.

@Test
public void collectDoubleWithTarget() {
    MutableDoubleCollection target = new DoubleArrayList();
    MutableDoubleCollection result = this.lazyIterable.collectDouble(PrimitiveFunctions.unboxIntegerToDouble(), target);
    Assert.assertEquals(DoubleArrayList.newListWith(1.0d, 2.0d, 3.0d, 4.0d, 5.0d, 6.0d, 7.0d), result.toList());
    Assert.assertSame("Target list sent as parameter not returned", target, result);
}

Example 2 with MutableDoubleCollection

use of org.eclipse.collections.api.collection.primitive.MutableDoubleCollection in project eclipse-collections by eclipse.
