示例1: LimitSizeTo
public void LimitSizeTo()
{
var subject = new Subject<Person>();
var scheduler = new TestScheduler();
var results = subject.ToObservableChangeSet<Person>(limitSizeTo: 100,scheduler: scheduler).AsAggregator();
var items = Enumerable.Range(1, 200).Select(i => new Person("p" + i.ToString("000"), i)).ToArray();
foreach (var person in items)
{
subject.OnNext(person);
}
scheduler.AdvanceBy(100000);
Assert.AreEqual(300, results.Messages.Count, "Should be 300 messages");
Assert.AreEqual(200, results.Messages.Sum(x => x.Adds), "Should be 200 adds");
Assert.AreEqual(100, results.Messages.Sum(x => x.Removes), "Should be 100 removes");
Assert.AreEqual(100, results.Data.Count, "Should be 1 item in the cache");
var expected = items.Skip(100).ToArray().OrderBy(p => p.Name).ToArray();
var actual = results.Data.Items.OrderBy(p => p.Name).ToArray();
CollectionAssert.AreEqual(expected, actual,"Only second hundred should be in the cache");
