Examples with Multimap org.eclipse.collections.api.multimap.Multimap used on opensource projects

Example 1 with Multimap

use of org.eclipse.collections.api.multimap.Multimap in project eclipse-collections by eclipse.

the class StackIterableTestCase method groupByEach.

@Override
@Test
public void groupByEach() {
    StackIterable<Integer> stack = this.newStackFromTopToBottom(1, 2, 3);
    MutableMultimap<Integer, Integer> expected = FastListMultimap.newMultimap();
    stack.forEach(Procedures.cast(value -> expected.putAll(-value, Interval.fromTo(value, stack.size()))));
    Multimap<Integer, Integer> actual = stack.groupByEach(new NegativeIntervalFunction());
    Assert.assertEquals(expected, actual);
    Multimap<Integer, Integer> actualWithTarget = stack.groupByEach(new NegativeIntervalFunction(), FastListMultimap.newMultimap());
    Assert.assertEquals(expected, actualWithTarget);
}

Example 2 with Multimap
