Query Batch: Concrete Syntax
time to read 3 min | 417 words

Thanks for all the feedback about this feature, I have implemented it and you can find the code here.  Instead of explaining, I am going to let the test speak for themselves. Consider this a first iteration, and I am now accepting patches for this. :-)

 

[Test]
public void CanUseCriteriaBatch()
{
    ICollection<SMS> loadedMSGs = null;
    new CriteriaBatch(session)
        .Add(DetachedCriteria.For<SMS>(), Order.Asc("id"))
        .OnRead<SMS>(delegate(ICollection<SMS> msgs) { loadedMSGs = msgs; })
        .Execute();
    Assert.IsNotNull(loadedMSGs);
}

[Test]
public void CanUseCriteriaBatchForUniqueResult()
{
    ICollection<SMS> loadedMSGs = null;
    SMS loadedMsg = null;
    new CriteriaBatch(session)
        .Add(DetachedCriteria.For<SMS>(), Order.Asc("id"))
            .OnRead<SMS>(delegate(ICollection<SMS> msgs) { loadedMSGs = msgs; })
        .Add(DetachedCriteria.For<SMS>())
            .Paging(0, 1)
            .OnRead<SMS>(delegate(SMS msg) { loadedMsg = msg; })
        .Execute();
    Assert.IsNotNull(loadedMSGs);
    Assert.IsNotNull(loadedMsg);
}

[Test]
public void CanUseCriteriaBatchWithAutomaticCountQuery()
{
    ICollection<SMS> loadedMSGs = null;
    int msg_count = 0;
    SMS loadedMsg = null;
    new CriteriaBatch(session)
     .Add(DetachedCriteria.For<SMS>(), Order.Asc("id"))
         .OnRead<SMS>(delegate(ICollection<SMS> msgs, int count) { loadedMSGs = msgs;
                                                                     msg_count = count;})
     .Add(DetachedCriteria.For<SMS>())
         .Paging(0, 1)
          .OnRead<SMS>(delegate(SMS msg) { loadedMsg = msg; })
    .Execute();
    Assert.IsNotNull(loadedMSGs);
    Assert.AreEqual(1, msg_count);
    Assert.IsNotNull(loadedMsg);
