public class AutomaticLatch
extends AbstractLatch
```
An automatic latch has the same semantic as the ReusableLatch However this class has a replaceable callback that could be called when the number of elements reach zero. With that you can either block to wait completion, or to send a callback to be used when it reaches 0.
