Examples with ImmutableList org.eclipse.collections.api.list.ImmutableList used on opensource projects

Example 1 with ImmutableList

use of org.eclipse.collections.api.list.ImmutableList in project eclipse-collections by eclipse.

the class AbstractImmutableListTestCase method groupByEach.

@Test
public void groupByEach() {
    ImmutableList<Integer> list = this.classUnderTest();
    MutableMultimap<Integer, Integer> expected = FastListMultimap.newMultimap();
    list.forEach(Procedures.cast(value -> expected.putAll(-value, Interval.fromTo(value, list.size()))));
    Multimap<Integer, Integer> actual = list.groupByEach(new NegativeIntervalFunction());
    Assert.assertEquals(expected, actual);
    Multimap<Integer, Integer> actualWithTarget = list.groupByEach(new NegativeIntervalFunction(), FastListMultimap.newMultimap());
    Assert.assertEquals(expected, actualWithTarget);
}

Example 2 with ImmutableList

use of org.eclipse.collections.api.list.ImmutableList in project eclipse-collections by eclipse.

the class MutableListTestCase method MutableList_shuffleThis.

@Test
default void MutableList_shuffleThis() {
    Integer[] integers = Interval.oneTo(50).toArray();
    MutableList<Integer> mutableList1 = this.newWith(integers);
    MutableList<Integer> mutableList2 = this.newWith(integers);
    Collections.shuffle(mutableList1, new Random(10));
    assertEquals(mutableList1, mutableList2.shuffleThis(new Random(10)));
    MutableList<Integer> list = this.newWith(1, 2, 3);
    UnifiedSet<ImmutableList<Integer>> objects = UnifiedSet.newSet();
    while (objects.size() < 6) {
        objects.add(list.shuffleThis().toImmutable());
    }
    Interval interval = Interval.oneTo(1000);
    MutableList<Integer> bigList = this.newWith(interval.toArray());
    MutableList<Integer> shuffledBigList = bigList.shuffleThis(new Random(8));
    MutableList<Integer> integers1 = this.newWith(interval.toArray());
    assertEquals(integers1.shuffleThis(new Random(8)), bigList);
    assertSame(bigList, shuffledBigList);
    assertSame(bigList, bigList.shuffleThis());
    assertSame(bigList, bigList.shuffleThis(new Random(8)));
    assertEquals(interval.toBag(), bigList.toBag());
}
